Battery energy storage system in peak shaving application

Abstract

This paper focuses on the performance of battery energy storage system (BESS) in peak shaving application. BESS technologies have a great potential in supplying the power especially during on-peak period, thus reducing the peak generation. This technique is very important especially for commercial and industrial sectors since they have to pay to a utility company some additional costs of 30% of their peak demand due to the usage of expensive open-cycle gas power plants. This paper also discusses the effectiveness of using a lithium-ion battery in reducing the power generation during peak demand. This kind of battery is chosen due to its high efficiency in charging and discharging as well as its high energy density. The performance of the proposed battery is analysed using Matlab/Simulink simulation. The result shows that the lithium-ion battery is very effective in supplying demand during on-peak period.
