Economic Dispatch in Renewable Energy Based Microgrid Using Manta Ray Foraging Optimization

In this paper, the renewable based microgrid (MG) has planned to meet the electric power demand. The operating cost of distributed generator (DG) are mostly depend on their types, thus load dispatch has performed to evaluate the operating cost of different DG operating under their respective limits. For optimization, Manta ray foraging optimization (MRFO) has used to determine the best solution to minimize the total operating cost. The MRFO is a new metaheuristic approach inspired by the behavior and foraging techniques of manta ray, to search for their food in the ocean. The effectiveness of the MRFO has demonstrated through its comparison with the other existing techniques reported in different literature. Further, the impact on cost reduction with the integration of solar and energy storage system, are also analyzed at different electric power demand.
