Micro-Grid Dynamic Economic Dispatch with Renewable Energy Resources Using Equilibrium Optimizer

Micro-grid is a small power system that consists of one or more generation sources managed by customers to satisfy their load demands for having the more economic and reliable state. Micro-grids may include conventional and renewable resources. Thus, the Economic Dispatch (ED) is utilized as an important tool for scheduling these resources to minimize the generation cost. In this paper, the economic dispatch of a Microgrid (MG) is solved using one of the newest algorithms called Equilibrium Optimizer (EO). The aim of ED is assigning the optimal scheduling of the distributed generators in 24-h-ahead of a MG which includes two wind turbines, three fuel-cell units and two diesel generators. The simulation results reveal to that the EO is an efficient technique for solving the dynamic economic dispatch of the MG. Moreover, the proposed algorithm is superior compared with the other reported algorithm in terms of generation cost minimization.
