The objective of rotor kinetic energy regulations is to add a frequency control interface to the active power control system of a wind farm, which also provides fast frequency regulations power by delivering the rotor's kinetic energy to maintain the system's frequency constant.
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 ].
The coal-based system is restricted in its capacity to give the frequency control due to the limitation of the power ramp rate. Therefore, this advanced energy storage system is suited to high-frequency operation.
The speed regulation of the governor is around 5% from zero to full load. Energy storage systems supply power to the load when there is a shortage of power supply from the grid and effectively maintain the stability of the power system because of its fast response.
The energy storage system generating-side contribution is to enhance the wind plant's grid-friendly order to transport wind power in ways that can be operated such as traditional power stations. It must also be operated to make the best use of the restricted transmission rate. 3.2.2. ESS to assist system frequency regulation
