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.
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 .
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.
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.
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.
Aiming at the problems of low climbing rate and slow frequency response of thermal power units, this paper proposes a method and idea of using large-scale energy storage battery to respond to the frequency change of grid system and constructs a control strategy and scheme for energy storage to coordinate thermal power frequency regulation.
