Abstract
Given the prohibited operating zones, losses, and valve point effects in power systems, energy optimization analysis in such systems includes numerous nonconvex and nonsmooth parameters, such as economic dispatch problems. In addition, in this paper, to include all possible scenarios in economic dispatch problems, multifuel generators, and transmission losses are considered. However, these features make economic dispatch problems more complex from a nonconvexity standpoint. In order to solve economic dispatch problems as an important consideration in power systems, this paper presents a modified robust, and effective optimization algorithm. Here, some modifications are carried out to tackle such a sophisticated problem and find the best solution, considering multiple fuels, valve point effect, largescale systems, prohibited operating zones, and transmission losses. Moreover, a few complicated power systems including 6, 13, and 40 generators which are fed by one type of fuel, 10 generators with multiple fuels, and two largescale cases comprised of 80 and 120 generators are analyzed by the proposed optimization algorithm. The effectiveness of the proposed method, in terms of accuracy, robustness, and convergence speed is evaluated, as well. Furthermore, this paper explores the integration of cloud storage and internet of things (IoT) to augment the adaptability of monitoring capabilities of the proposed method in handling nonconvex energy resource management and allocation problems across various generator quantities and constraints. The results show the capability of the proposed algorithm for solving nonconvex energy resource management and allocation problems irrespective of the number of generators and constraints. Based on the obtained results, the proposed method provides good results for both small and large systems. The proposed method, for example, always yields the best results for the system of 6 power plants with and without losses, which are $15,276.894 and $15,443.7967. Moreover, the improvements made in the proposed method have allowed the economic dispatch problem regarding multifuel power plants to be solved not only with optimal results ($623.83) but also in less than 35 iterations. Lastly, the difference between the bestobtained results ($121,412) and the worstobtained results ($121,316.1992) for the system of 40 power plants is only about $4 which is quite acceptable.
Introduction
Over the past decade, energy resource management and allocation have become key challenges for modern societies [1, 2]. The Economic Dispatch (ED) problem is one of the most crucial optimization issues in the operation and energy resource management and allocation of power systems. In this problem, considering the demanded load and transmission network losses, the output of each generator is determined to minimize fuel costs. Additionally, the output of each unit must satisfy power generation constraints [3]. This means that all information regarding the demanded load and each generator is gathered in one place and analyzed centrally. This aligns perfectly with the concept of cloud storage. Furthermore, to address the need for efficient information exchange, our approach involves a bidirectional flow of information. The cloudbased central system sends and receives all relevant data, while each unit receives and transmits information. This exchange is designed to be fast, secure, and intelligent, incorporating principles of IoT networks, which plays a significant role in our proposed methodology (see Fig. 1).
The mathematical methods, such as the lambda iteration method [5], gradient method [6], Newton method [7], linear programming [8], quadratic programming [9], and Lagrangian multiplier method [10], can be used to solve the economic dispatch problems with smooth and monotonic cost function [11]. In [12], dynamic economic dispatch problems have been solved by Lagrangian relaxation, while the Lagrangian multipliers have been updated through the quasinewton process. The mathematical methods can find the best global solution in less number of iterations and hence converge faster [13]. However, in practical scenarios, the fuel cost function curves are nonconvex and discontinue induced by valve point effect, losses, the impact of multiple fuels, and prohibited operating zones [14], which can hinder the applicability of these methods. To model the, a sinusoidal term is added to the traditional quadratic cost function of the economic dispatch problems [15], which brings about additional complexity. Moreover, as the number of decision variables increases, the mathematical complexity increases, and the problem becomes less tractable.
In order to address these issues, some metaheuristics methods, such as fuzzy adaptive particle swarm optimization [16], hybrid genetic algorithm [17], and improved fast evolutionary programming [18] have been utilized. The nonsmooth economic dispatch problems have been solved utilizing the fuzzy adaptive particle swarm optimization method in [16], while the NelderMead process, like a local search algorithm, searches around the achieved solution in each iteration, which brings about more robustness [16]. In [17] the genetic algorithm, as the main optimization method, is used to tackle the economic dispatch problem with a nonsmooth cost function. Sequential quadratic programming tunes the genetic algorithm in each trial run while the maximum entropy principle approximates the cost function to improve the process [17]. Authors in [18] have used improved fast evolutionary programming to solve the nonconvex economic dispatch problem. Although these algorithms found the optimum solution, they need parameter tuning during the optimization process, which hinders their applicability of them. In addition, none of these algorithms considers the effect of multifuel generators and prohibited operating zones in solving the economic dispatch problem.
Several works have either considered the prohibited operating zones or multifuel generators separately. The multi Tabu search algorithm equipped with salient mechanisms, genetic algorithm, and evolutionary strategy optimization algorithms proposed in [19,20,21] have solved the economic dispatch problem by considering only prohibited operating zones constraint. However, multiple fuel assumption, which makes the economic dispatch problems even more complex, is not considered in their framework. The optimal solution to the economic dispatch problem in the presence of valve point effects and multifuel generators is achieved by an improved genetic algorithmmultiplier updating method [22]. In fact, this method finds the optimal solution while it handles the equality and inequality constraint. However, the prohibited operating zones constraint, which is an important limiting factor in realworld scenarios, is not considered. In fact, generating power in these prohibited intervals may damage the generators. Therefore, a powerful and holistic method of solving nonconvex and nonsmooth economic dispatch problems with sophisticated constraints of having various combinations of generated power, considering the valve point effects, prohibited operating zones, and transmission loss is yet to be investigated.
Gap analysis
As it is obvious, providing a robust framework that can be utilized to solve complex economic dispatch problems in small and largescale systems is vital. Moreover, this framework should be easy implementing with an acceptable convergence speed. Hence, in this paper we seek to cover these challenges in solving economic dispatch problems.
One of the new methods of finding the global solution to such problems is to use the JAYA algorithm [23]. In this algorithm, the particle must move toward the best solution and avoid the worst one, in each iteration, to find the optimal solution. However, the JAYA algorithm is still not capable of providing the optimal solution in certain cases, which are shown in the results section of the presented paper, in detail. In fact, there are realworld scenarios where JAYA needs to be modified to provide the optimal solution.
In this paper, a newly modified optimization algorithm called modified JAYA is proposed to solve nonconvex and nonsmooth economic dispatch problems in small, medium, and largescale systems where prohibited zones, losses, the impact of multiple fuels, and valve point effect are considered. Moreover, all possible moving states to get away/move towards the worst/best solution are considered. In addition, by adaptively selecting the population size through a mutation operator, the convergence rate and the effectiveness of the algorithm are improved. Furthermore, a new and proper process satisfies the exact demanded load, as the most important goal in energy resource management and allocation.
Research questions

Is the proposed method effective in extracting the optimal solutions in small and largescale systems?

Is the convergence speed suitable for finding optimal results in the proposed method?

Is the proposed method effective in fulfilling the equal constraint, which is the provision of the demanded electrical power?

How effective is the proposed method in the ED problem with multifuel power plants?
The rest of this paper is organized as follows. Section 2 illustrates the modeling of nonconvex economic dispatch problems. Moreover, the role of multifuel generators and network losses is discussed. The proposed algorithm formulation is presented in Sect. 3. Section 4 presents the application of the modified JAYA algorithm in economic dispatch problems. Section 5 describes the test systems and simulation results. Finally, Sect. 6 draws conclusions.
Nonconvex economic dispatch problem formulation
In order to better describe the advantages of the modified JAYA algorithm (MJAYA) algorithm, economic dispatch (ED) problems with convex and nonconvex fitness functions are initially presented in subsections 2.1 and 2.2, respectively. In addition, the ED problem constraints, including power balance constraint, prohibited operating zones (POZs) Constraint, and output power constraint are introduced in subsection 2.3.
The ED problem with convex fitness function
The ED problems aim to minimize the total energy cost while all constraints are satisfied. Using a seconddegree polynomial equation, the ED problem, aiming to minimize the cost of the generated power, is formulated by [24],
where vector \(X\) is the decision variables. As stated before, ED problems with multifuel generators are also investigated in this paper. As a result, such ED problems are represented by Eq. (2).
where, \(\{ a_{i1} ,...,a_{iz} \} ,\{ b_{i1} ,...,b_{iz} \} ,\{ c_{i1} ,....c_{iz} \}\) being the cost coefficients of \(i^{th}\) generator with a fuel type of \(1,2,....,z\).
The ED problem with nonconvex fitness function
When valves are opened to increase electrical power, it introduces mechanical losses which in turn brings about nonconvexity and nonsmoothness to the ED model. In order to take the network losses as well as POZs into account, we include them as constraints in the optimization problem. In addition, the valve point effect (VPE) effect is modeled by adding a sinusoidal term to the cost function [25]. The developed ED problem with the VPE effect is formulated in (3). Figure 2 represents the nonconvex cost function with four VPEs.
Constraints
Power balance constraint
Supplying demanded load is one of the most important goals in energy resource management and allocation [26] and ED problems. In literature, this constraint is called the power balance constraint and is expressed as
where P_{D} denotes the total demanded load. Moreover, P_{L} is the total transmission network losses and can be approximated by
Prohibited operating zones constraint
In practical situations, all units should not generate output power during POZ intervals. In fact, generating power in POZs may damage generators. The cost function with two POZs is shown in Fig. 3.
To apply this constraint, the output power between POZ intervals is fixed to the near boundary of the POZ interval. The detailed expression of the POZ constraint is given by
Output power constraint
The output power of each generator is bounded to certain values as in (7).
Modified JAYA algorithm
In order to effectively introduce the MJAYA algorithm and showcase its advantages, we first provide a brief overview of the conventional JAYA algorithm.
Original JAYA Algorithm
JAYA is a Sanskrit word meaning victorious [23]. In JAYA, as a new and simple algorithm, the particles move towards the best solution and retreat from the worst one in each iteration, until the optimal solution is eventually achieved [22, 26]. The main advantages of this algorithm are simple implementation, low computational complexity, and the ability to work without control parameters [23]. This algorithm changes the position of candidate solutions by
where \(X_{s,t,best}\) and \(X_{s,t,worst}\) are the best and worst solutions of \(H\left( X \right)\) in the \(k^{th}\) iteration, respectively.
Modified JAYA algorithm
As mentioned previously, power balance constraints, increasing the dimension of power network decision variables, and other critical complications, hinder the JAYA algorithm in performance and quality. Therefore, in order to circumvent the aforementioned drawbacks, three changes need to be applied to the conventional JAYA algorithm. The proposed modifications are presented in the following subsections.
Increment of the algorithm ability
Unlike the JAYA algorithm, the proposed algorithm checks all possible moving states for i^{th} solution \(\left({X}_{i,k}^{new}\right)\) according to (9),
In addition, an augmented matrix is produced as follows
Consequently, the cost vector of the achieved solution in the k^{th} iteration is calculated.
Then, the corresponding \(\tilde{X}_{i,k}^{new}\) to the least cost is chosen as the i^{th} solution. The corresponding pseudocode for MJAYA algorithm is provided in Algorithm 1, lines 3, 14 and 15.
Increment of convergence speed
One of the important factors determining the convergence speed of algorithms is the number of swarm populations. An algorithm may not find the optimum solution if a very small population size is chosen. In addition, increasing the size of the population prolongs the execution time. In fact, there is a tradeoff between the accuracy of the optimal solution and the speed of the convergence. Therefore, it is recommended to select the population size, adaptively. We can start with small swarm sizes, due to the inherent diversity of the population in the initial stage. After a few iterations, the resemblance among the swarms will increases and we can add new swarms at any iteration. This can guarantee that the algorithm never remains in local minima. To increase the effectiveness and reduce the execution time of the MJAYA algorithm, the population size can be determined using (12). The corresponding pseudocode is provided in Algorithm 1 lines 17 and 18.
In Eq. 12, the lowest and highest population sizes are \(N_{\min }\) and \(N_{\max }\), respectively. In addition, \(N\) represents the size of the population that is adopted in each iteration.
Increment of algorithm effectiveness
The mutation operator is another important strategy to skip local minima. The mutation operator changes the position of the candidate solutions and almost boosts the population search in the whole space of the problem. Like population size, it is better to apply less mutation in the beginning and more at the end of the optimization procedure to achieve better performance and higher convergence speed. Therefore, three mutated solutions for the i^{th} solution are provided in (13).
where \(b_{1} \ne b_{2} \ne b_{3} \ne b_{4} \ne b_{5}\) are random constants and unequal to \(b_{i}\). Additionally, \(X\) represents the decision variable, here the generation output. \(rand\,\) is also denoting a random amount. The cost functions of the mutated and the i^{th} solutions are evaluated and the one with the lowest value is substituted for the i^{th} solution according to the pseudocode in Algorithm 1, lines 4–15,
Application of the MJAYA algorithm in solving economic dispatch problem
In this section, the application of the proposed method to solve the ED problem, an important problem in energy optimization, is described in detailed steps.

Step 1: Define input parameters
The generator data, fuel cost coefficients, POZs intervals of each unit, the amount of demanded load, and loss coefficients are defined.

Step 2: Initialize the population
A random population is initialized using (14) and (15).
where \(P_{gi}\) denotes the i^{th} candidate solution vector for the generated power. Additionally, for each generator, \(P_{gi\min }\) and \(P_{gi\max }\) represent the minimum and maximum boundaries of generation.

Step 3: Satisfy the power balance constraint
In order to satisfy the active power and load balance requirements, the power balance constraint must be met [27]. In Fig. 4, a flowchart is portrayed where this constraint is satisfied eventually.

Step 4: Evaluate the fitness function
We integrate the constraints into the cost function using the method of Lagrangian multipliers. Therefore, using Lagrangian duality, the dual problem of the original optimization problem (2) can be given by.
where, \(\lambda_{i}\) and \(\mu_{j}\) are Lagrangian multipliers. In addition, \(h_{i} (X)\) and \(g_{j} (X)\) are equality and inequality constraints, respectively. Note that, in (16), there are m equality and p inequality constraints integrated into the cost function.
In ED problems, the generated power can be controlled manually through a variable. Hence, if the suggested solution by MJAYA is not between the minimum/maximum values, the output power is set to the minimum/maximum boundary. In addition, considering the fact that the equality constraint has already been satisfied through step 3, the cost function is obtained as

Step 5: Obtain the worst and best solutions
In this step, the solution with minimum/maximum cost is selected as the best/worst solution.

Step 6: Apply the MJAYA to the particles according to the pseudocode represented in Algorithm 1

Step 7: Satisfy the Equality constraint as in Step 3

Step8: Evaluate the fitness function for new solutions

Step 9: Update the best and worst solutions
In each iteration, the bestobtained solution is considered the global optimal solution.

Step 10: iteration = iteration + 1.
If the convergence condition or maximum iteration is reached, then the process is terminated; otherwise, the algorithm returns to step 6.

Step 11: Print the best cost for the best power output for each generator
Simulation results
In this section, we study the effectiveness of the MJAYA algorithm by evaluating the energy optimization problem in the ED problem, for five different cases. For a quick reference, these cases are given in Table 1. Moreover, a PC with the following specification is utilized.
RAM: 8 GB, CPU: 2.6 GHz.
Case I: 6 generators with and without loss
This system contains six generators without a valve point effect. The demanded load is 1263 MW and the loss coefficients of this system are presented in (18). In addition, the POZs information is presented in Table 2. The obtained optimum solutions by MJAYA, JAYA, TLBO, PSO, GA, DE, and TS algorithms for the system with and without losses are presented and compared in Tables 3 and 4, respectively.
As mentioned previously, the most important goal in ED problems is supplying demanded load while the power network loss is considered. The exact value of losses must be calculated by solving power flow equations. However, in ED problems, this is estimated by (5). It is obvious that the generated power variation changes the net loss. Hence, it is important to find a proper output in the way that the power balance constraint is met while the cost function is minimized. As it can be seen in Table 3, the MJAYA algorithm outperforms the conventional JAYA and the other methods. The reason is mainly due to the modifications applied to the JAYA algorithm. In fact, the proposed MJAYA algorithm performs better, in not getting stuck in local minima, compared to JAYA.
Moreover, Table 4 represents a comparison between MJAYA, JAYA, GA, TS, and DE algorithms in 6 generators system considering losses. It has been shown that the performance of MJAYA is better than the other algorithms. It should be noted that computational time to extract results for JAYA algorithm is 1.35 s, while it is 0.96 s for the proposed modified JAYA algorithm.
Case II: 10 multifuel generators with 2700 MW load demand
The ED problem with multifuel generators is analyzed in the proposed method. In this case, the cost coefficients of generators are changed due to the utilization of different sorts of fuels such as coal, natural gas, and oil. It is necessary to select the appropriate fuel type to have an economically efficient cost.
The current system contains 10 generators and the demanded load is 2700 MW. The first generator is fed by two types of fuels while the others are fed by three types of fuels [22]. Table 5 provides the results of the MJAYA and JAYA algorithms in this case and the results are compared to the proposed methods in [22], as well.
It can be seen in Table 5 that JAYA and MJAYA’s results are reasonable. However, MJAYA yields the optimal solution which depicts the effectiveness and advantages of MJAYA modifications. In addition, the convergence curves for both methods are shown in Fig. 5 to illustrate the enhancement of MJAYA compared to JAYA. As we can see, MJAYA converges faster and smoother compared to the conventional JAYA.
Furthermore, MJAYA obtains the optimum cost function by about 40 iterations; while JAYA achieves a suboptimal solution in higher iteration (i.e., 120 iterations). Therefore, the proposed modifications in MJAYA are effective to increase the speed and accuracy of the algorithm. It should be noted that computational time to extract results for JAYA algorithm is 3.85 s, while it is 2.74 s for the proposed modified JAYA algorithm.
Case III: 13 generators with 1800 MW and 2520 MW load demands
There are thirteen generators in this case, while VPE is taken into account. The generators data for this system is given in [29]. This system has many local minima and some of the algorithms are stuck in one of these points [16 17, 18, 30]. To examine the performance of the proposed method, it is applied to this system with two different demanded load amounts, namely 1800 MW and 2520 MW. Moreover, Tables 6 and 7 present a comparison of MJAYA’s results and some wellknown methods, respectively.
It has been shown in Tables 6 and 7 that the worst cost obtained by the proposed algorithm is lower than the best solution obtained by the other algorithms. In addition, the obtained worst, mean and best costs by MJAYA are close to each other. In other words, the variance of the costs is low, meaning that the proposed algorithm is proper enough to be utilized in energy optimization. It should be noted that computational time to extract results for the MJAYA algorithm are 3.56 and 2.49 s, respectively.
Case IV: 40 generators with 10500 MW load demand
This system contains 40 generators considering VPEs. The total demanded load is 10,500 MW and the data for this system is given in [18]. This system includes more elements of creating nonconvexity in the problem, meaning that there are more local minima compared to the previous case studies. This case is of great importance and very close to practical energy resource management and allocation scenarios. MJAYA algorithm is applied to this case to compute the optimum solution. Results are shown and compared to the wellknown algorithms suggested by [16, 17], in Table 8.
As shown in Table 8, the best value obtained by MJAYA is better than the obtained values by other methods, meaning that MJAYA outperforms the other algorithms in such cases. Furthermore, Fig. 6 shows the convergence curve of JAYA and MJAYA algorithms for 10 independent runs. It should be noted that computational time to extract results for JAYA algorithm is 52 s, while it is 46.9 s for the proposed modified JAYA algorithm.
Robustness is another important feature that an algorithm must possess. In fact, an algorithm is robust if the bestobtained solutions in each trial run are close to each other. As shown in Fig. 6, the best costs achieved by MJAYA in trial runs are almost the same, meaning that the MJAYA algorithm is robust enough to handle complex energy optimization problems.
In order to check the effectiveness of the MJAYA algorithm in considering the output power constraint in the ED problem, Case IV is selected. Figure 7 shows the output power, minimum, and maximum generation limit of each unit in this case.
Case V: 80 and 120 generation units
Most of the existing algorithms for solving ED problems in large dimension problems are either unable to achieve the optimum solution or do not converge to the optimal solution with a reasonable number of iterations. To this end, the performance of the MJAYA algorithm in larger systems containing 80 and 120 generators is tested. The data of the generators and demanded load are double and triple the data of the 40 generators system (Case IV), respectively. The obtained results by MJAYA methods are shown in Table 9. It is seen that the proposed MJAYA algorithm does not suffer from enlarging the dimension.
The MJAYA algorithm benefits from three modifications which are mentioned in section III. In order to demonstrate the effect of each modification, Table 10 provides a comparison between them in the case when the number of generators is 80. In the first state, JAYA is implemented without any modification (JAYA1). The second stage is the first modification which is applied to JAYA (JAYA2). The mutation operator is implemented in the third state (JAYA3) while all modifications are applied to JAYA (MJAYA) in the last state.
As presented in Table 10, each of the obtained solutions in each state is reasonable. However, MJAYA’s result is better than other states. The convergence characteristics of each state and also MJAYA for case V are shown in Fig. 8.
It is evident from Fig. 8 that by utilizing all modifications the optimal solution can be achieved in fewer iterations.
Discussion
According to the introduction section, solving complex optimization problems is a fundamental challenge for the JAYA algorithm. As a result, various papers seek to improve the performance and efficiency of the JAYA algorithm. The majority of papers recommend combining this algorithm with other optimization methods, or processes [32,33,34,35] that increase local search capability. In general, combining two methods causes complexity and often requires parameter setting. Despite obtaining the optimal results, this solution typically slows convergence, increases complexity, and increases calculation time. Thus, in this paper, we aim to improve the algorithm capability, convergence speed, and efficiency of the JAYA algorithm through some simple but straightforward modification process (see Sect. 3). In the proposed modification, no control parameters are required for the improvement, and the solution is faster than the combined algorithms [6,7,8,9,10,11,12,13,14,15,16,17,18,19,20]. It is also important to note that these modifications can be used for any other optimization algorithm and increase its efficiency. This is why the proposed method is new, and the results also prove it.
Future trend
The modified optimization algorithm proposed in this paper can be applied in a wide range of applications requiring highperformance computational intelligence techniques. The applications cover a wide range of realworld uses, including healthcare systems, industrial platforms, and smart cities. With this optimizer, it is possible to implement applications through IoT, edge/fog, and cloud architectures [36,37,38,39,40,41,42,43,44,45]. The proposed algorithm can be also used in other areas of computational sciences such as remote sensing systems and control systems, where there is an advanced problem of weight optimization [46,47,48,49].
Conclusion
The ED problem is one of the important problems in the energy optimization area which tries to supply the net demanded load with minimum fuel cost. In this paper, we considered some complicated and practical constraints such as VPEs, POZs, and multifuel generators. These constraints make ED problems more complex from a nonconvexity and nonsmoothness point of view. Hence, a new modified JAYA algorithm was introduced in this paper to handle such a complicated problem. Roughly speaking, the effectiveness and ability of MJAYA were increased by considering all moving possible states and adding a mutation operator. In addition, the convergence speed of the proposed algorithm was enhanced by adaptively utilizing population size. The MJAYA’s results were compared with some wellknown metaheuristic algorithms in ED problems. The simulation results showed that the proposed MJAYA algorithm has a better performance in terms of accuracy and robustness of convergence as well as the capability of finding the optimal solution. The performance and effectiveness of this method were also demonstrated in different case studies of ED problems. It was shown that the proposed algorithm can be used to solve any constrained and unconstrained energy optimization problems.
Numerical results showed that the proposed algorithm has advantages such as simplicity, robustness, ability to work without control parameters, and capability in dealing with constraints irrespective of their difficulties.
