Study of Battery Sizing for Solar Power Plant

Abstract

Photovoltaic is one of the products of renewable energy-based electrical energy generation technology, without using fossil fuels, even without mechanical movements in the energy conversion process. Photovoltaic depends only on photons from solar rays. The sensitivity is relatively high against the sun's irradiance, so because of that, both the output voltage and current become unstable. However, the instability of photovoltaic in producing electricity needs to be fixed by adding power storage component, such as batteries. The purpose of this paper is to design an optimal system to measure the size of the battery in Solar Power Plant. The best sizing battery is 80MW with 194 cells.
