In terms of developments in China, 19 members of the National Power Safety Production Committee operated a total of 472 electrochemical storage stations as of the end of 2022, with a total stored energy of 14.1GWh, a year-on-year increase of 127%.
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 .
With the rapid expansion of new energy, there is an urgent need to enhance the frequency stability of the power system. The energy storage (ES) stations make it possible effectively. However, the frequency regulation (FR) demand distribution ignores the influence caused by various resources with different characteristics in traditional strategies.
According to CNESA data, the capacity of independent energy storage stations planned or under construction in China in the first half of 2022 was 45.3GW, accounting for over 80% of all new energy storage projects planned or under construction.
