Frequency Control with Dead Band Characteristic of Battery Energy Storage System for Power System Including Large Amount of Wind Power Generation

Abstract

This paper proposes a frequency control of a battery energy storage system applied for frequency deviation suppression in power system including a large amount of wind power generation. The power system of 5,000MW capacity with governor free control and load frequency control is assumed for the study, and wind power generation of 500MW capacity is assumed. The battery energy storage system is assumed to be added for the frequency control in the power system. Suitable frequency control functions of the battery energy storage system and suitable capacity of the battery energy storage system which coordinate with conventional frequency controllers in the power system are reported.
