Corresponding to today's accelerating socioeconomic complexities and environmental perturbs, extensive sustainability, improved power standards, higher efficiencies, autonomous energy, reviewing optional renewable energy resources, and power flow stability has become a contemporary subject of interest. The energy stability is achieved despite power system complexity that consists of various loads and distributed energy resources (DERs), together with renewable energy system (RES), the electrical energy storage system (EESS), etc. A microgrid mostly consists of various energy systems that contribute immensely towards the power grid and carry out an expected outcome. More importantly, it enhances the energy costs and performance of the system's operation. A microgrid can operate in isolation mode or integrated into the main grid with considerable distinct distribution energy resources. The microgrid set up in both aspects is convenient for alleviating energy strain on the power grid, minimizing greenhouse gases originating from traditional energy generation, and improving power quality. A synopsis of an energy management system for a microgrid, especially DERs, is detailed to depict the implementation methods that aim to conduct an electrical system's energy flow exceptionally. The electrical design of the microgrid studied is identified to compare distinct alternative energy systems amid those aforementioned. The paper will examine the microgrid's performance at various climate and load conditions, observing the effects of power fluctuations on the energy storage system. This will be achieved using ETAP software. The simulation's basis is on the actual energy storage system and the photovoltaic production description within a day.
