An approach to the optimal operation of the microgrid with renewable energy sources and energy storage systems

This paper proposes a model for analyzing the production and storage of electricity in the microgrid. The purpose of the model is the analysis of electricity production and storage in the microgrid with the goal of satisfying load demand at minimal production costs and CO₂ emissions. Apart from the description of the model itself, the paper presents the results of the simulation of the production and storage of electricity in the microgrid which is a part of a distribution network. The microgrid uses a photovoltaic plant, a wind turbine, a small pumped hydro and diesel and gas generators for power generation, and battery energy storage systems and the reservoir of a small pumped hydro as energy storages.
