This paper develops a three-step process to assess the resource-adequacy contribution of energy storage that provides frequency regulation. First, we use discretized stochastic dynamic optimization to derive decision policies that tradeoff between different energy-storage applications.
Does BES provide emergency frequency regulation in energy storage planning?
(1) Compared to traditional energy storage planning methods focusing solely on peak shaving and frequency regulation, this paper considers the emergency frequency regulation capability of BES during planning, ensuring frequency security in the event of N- k faults.
Can large-scale battery energy storage systems participate in system frequency regulation?
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.
Does battery energy storage participate in system frequency regulation?
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.
Are battery frequency regulation strategies effective?
The results of the study show that the proposed battery frequency regulation control strategies can quickly respond to system frequency changes at the beginning of grid system frequency fluctuations, which improves the stability of the new power system frequency including battery energy storage.
