Abstract :This paper presents a method based on meta-heuristic to solve Dynamic Economic Dispatch insert ignore into journalissuearticles values(DED); problem in a power system. In this paper, Crow Search Algorithm insert ignore into journalissuearticles values(CSA);, which is one of the heuristic methods is proposed to solve the DED problem in a power system. In this study, line losses, generation limit values of generators, generation-consumption balance, valve-point effect and ramp rate limits of generator are included as constraints. The proposed algorithm was implemented on two different test cases. Finally, the CSA results were compared with the results of well-known heuristics in the literature such as Particle Swarm Optimization insert ignore into journalissuearticles values(PSO);, Genetic Algorithm insert ignore into journalissuearticles values(GA);, Symbiotic Organism Search insert ignore into journalissuearticles values(SOS); algorithm, Artificial Bee Colony insert ignore into journalissuearticles values(ABC); algorithm, Simulated Annealing insert ignore into journalissuearticles values(SA);, Imperial Competitive Algorithm insert ignore into journalissuearticles values(ICA);, Modified Ant Colony Optimization insert ignore into journalissuearticles values(MACO); algorithm. The results show that the proposed algorithm has a better operating cost. With the results of the algorithm proposed in the test system 1, a profit of $2,056,5931 per day and $751,751,4815 per year is obtained. It is seen that with the results of the algorithm proposed in the test system 2, a daily profit of $12,279,7328 and a yearly profit of $4,482,102,472 are obtained. Test systems are operated by using less fuel with the results of the proposed algorithm and thus the harmful gas emissions released by thermal production units to the environment are also reduced.
