Trade-off analysis of autonomous microgrid sizing with PV, diesel, and battery storage

Abstract

This paper introduces a trade-off analysis on the sizing of microgrid equipment aimed at autonomous application in remote regions. The microgrid includes a diesel engine, solar photovoltaic (PV) panels, and a battery storage. The performance of the microgrid is measured by environmental impact (CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> emission), and frequency stability. The sizing of the battery storage is analyzed when the load is supplied mainly by the diesel engine. From the simulation analysis, it was shown that there exists a certain front of trade-off between the battery size and other performance indices due mainly to the dynamic performance of the battery storage and to the variation of PV output under different weather conditions.
