As a new type of flexible regulatory resource with a bidirectional regulation function [ 3, 4 ], energy storage (ES) has attracted more attention in participation in automatic generation control (AGC). It also has become essential to the future frequency regulation auxiliary service market [ 5 ].
Frequency regulation in power system In power systems, frequency is the continuously changing variable which is influenced by the power generation and demand. A generation deficit results in frequency reduction while surplus generation causes an increase in the frequency.
The conventional synchronous machine based power plants provide FR from the generation side. While the RESs and energy storage can be deployed for FR on generation or transmission side.
