Analysis of the Parallel & Standalone Operation of PVES and BESS for Microgrid Applications with Varying Climatic Condition

Abstract

In today's time, fuel price and shortage of conventional sources like coal are the biggest concern worldwide. Henceforth, world is moving towards adapting green energy i.e. renewable energy for the production of the electricity. Renewable sources are available in nature. One can harness in the forms of the solar energy, the wind energy, the tidal energy, the biomass energy, the geothermal energy etc. These sources are environment friendly and clean to use to produce electricity. One issue which has to be addressed while using these sources is that they are weather and location dependent. So reliability on these sources alone is less which leads to combining other source, be it conventional or other renewable sources. This combination of two or more sources to generate power is called hybrid system and in this paper, we are considering PVES (Photo-Voltaic Energy System) as main source and BESS (Battery Energy Storage System) for storage purpose. The simulations studies and analysis for the parallel & standalone Operation of PVES and BESS is performed and proposed in this paper. The system is used for the DC microgrid applications. The MATLAB simulation analysis is done by varying climatic conditions i.e. change in insolation and change in temperature.
