Application of Energy Storage for Automatic Load and Frequency Control

Abstract

The study is devoted to the issue of creating an effective automatic load and frequency control system using modern electric energy storage systems based on high-capacity batteries. As part of the study, different types of regulators are considered. The authors proposed an approach to the implementation of a control system using battery energy storage systems. Comparative calculations of different control systems are performed and the advantage of the proposed approach is demonstrated. The study was carried out by numerical simulation of an automatic load and frequency control system with emergency disturbance. The efficiency of regulation was determined on the basis of the analysis of the accepted indicators of the regulation quality, namely, the maximum frequency deviation and the duration of the transient process. It was found that the use of high-speed battery energy storage systems in the automatic load and frequency control system shows the best performance in frequency stabilization, satisfying the regulatory requirements established in the power system.
