Currently, there have been some studies on the capacity allocation of various types of energy storage in power grid frequency regulation and energy storage. Chen, Sun, Ma, et al. in the literature have proposed a two-layer optimization strategy for battery energy storage systems to regulate the primary frequency of the power grid.
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.
To leverage the efficacy of different types of energy storage in improving the frequency of the power grid in the frequency regulation of the power system, we scrutinized the capacity allocation of hybrid energy storage power stations when participating in the frequency regulation of the power grid.
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.
When the frequency fluctuates, energy storage stations can swiftly respond to the frequency changes in the power system, offering agile regulation capabilities and maintaining system stability . Thus, the participation of energy storage stations is also crucial for ensuring the safety and stability of operations in the power system .
