The application of energy storage in power grid frequency regulation services is close to commercial operation . In recent years, electrochemical energy storage has developed quickly and its scale has grown rapidly , . Battery energy storage is widely used in power generation, transmission, distribution and utilization of power system .
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.
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.
In recent years, the use of large-scale energy storage power supply to participate in power grid frequency regulation has been widely concerned. The charge and discharge cycle of frequency regulation is in the order of seconds to minutes. The state of charge of each battery pack in BESS is affected by the manufacturing process.
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.
