Operation Analysis and Optimization Suggestions of User-Side Battery Energy Storage Systems

Abstract

In recent years, with the development of battery energy storage technology and the support of policy, the construction scale of user-side battery energy storage system is increasing rapidly, and its operation performance has become more and more valued. In-depth quantitative analysis and evaluation is of great significance to provide reliable guarantee for high efficiency, safety and reliability operation of energy storage system. Based on the principles of scientificity, comprehensiveness and operability, the operation evaluation indexes are proposed including charge-discharge performance, energy efficiency, safety, reliability and economic performance. The operation performance of an example battery energy storage system for peak-load shifting is quantitatively analyzed and evaluated, based on the operation data and field test data. And the optimization suggestions are given for the problems existing in the operation of the system. The results show that the proposed operation evaluation indexes and methods can realize the quantitative evaluation of user-side battery energy storage systems on the charge-discharge performance, energy efficiency, safety, reliability and economic performance, which are helpful for the operation and maintenance of user-side battery energy storage systems.
