Optimal sizing of distributed energy resources in microgrid considering wind energy uncertainty with respect to reliability

In this paper, optimal sizing of Distributed Energy Resources (DERs) in Microgrid (MG) is proposed. MG includes photovoltaic (PV)/wind hybrid system with storage energy system that contains electrolyzer, hydrogen tank, fuel cell and battery. Wind power uncertainty is proposed and reliability index is considered as a constraint. Particles Swarm Optimization (PSO) Algorithm is used to obtain global optimal solutions. A study case is chosen and the best combination of DERs is obtained.
