Operation Method of Energy Storage System Replacing Governor for Frequency Regulation of Synchronous Generator without Reserve

This paper proposes an operation methodology for interfacing synchronous generator and energy storage system (ESS) by replacing conventional governor. research introduces management scheme with droop control method frequency regulation in coordination generator. For regulation, can take advantage of the ESS instead governor, its relatively fast characteristics, leading to less frequent deviation verification, we simulate a network reduction model from real Korean data, based on case studies using PSCAD/EMTDC software.
