Battery Energy Storage System Impact Over Load Frequency Control In Microgrids

Abstract

In the last few years, the price of battery energy storage (BES) technology (e.g. Lithium-Ion) has fallen tremendously and the cost of generating electricity from renewable energy sources has also decreased, and the trend is increasing. Therefore, the challenge to integrate the low-cost renewable electricity and low-cost storage to compete with conventional electricity generated from fossil fuels is the focus in recent research where BES is the key solution for this challenge. In this paper, the integration of BES into an isolated microgrid (MG) is investigated. This paper study the impact of a BES system on the frequency deviation as one of the critical applications to maintain grid stability considering the main characteristics of the BES and under different disturbances scenarios in an islanded MG. Overall, this paper introduces an open modular framework for future work on the performance of BES technologies from the technical aspect of different grid applications.
