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.
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 .
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.
