In the end, a control framework for large-scale battery energy storage systems jointly with thermal power units to participate in system frequency regulation is constructed, and the proposed frequency regulation strategy is studied and analyzed in the EPRI-36 node model.
Since the battery energy storage does not participate in the system frequency regulation directly, the task of frequency regulation of conventional thermal power units is aggravated, which weakens the ability of system frequency regulation.

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 .
In Ref., an operational cost model for a hybrid energy storage system considering the decay of lithium batteries during their life cycles was proposed to primarily minimize the operational cost and ES capacity, which enables the best matching of the ES and wind power systems.
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.
The FR cost of a regional grid is composed of the TPU costs F1 and the ES station costs F2. The TPU output and the ES station output are decision variables. For the TPU, the FR leads to power deviation from the optimal operating point, which in turn leads to increased wear and tear.
