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.
The fuzzy theory approach was used to study the frequency regulation strategy of battery energy storage in the literature , and an economic efficiency model for frequency regulation of battery energy storage was also established. Literature proposes a method for fast frequency regulation of battery based on the amplitude phase-locked loop.
The comprehensive efficiency evaluation system of energy storage by evaluating and weighing methods is established. The multi-level power distribution strategy based on comprehensive efficiencies of energy storage is proposed. With the rapid expansion of new energy, there is an urgent need to enhance the frequency stability of the power system.
With the gradual increase of energy storage equipment in the power grid, the situation of system frequency drop will become more and more serious. In this case, energy storage equipment integrated into the grid also needs to play the role of assisting conventional thermal power units to participate in the system frequency regulation.
After receiving the FR power distributed by the power grid, the ES station redistributes it to each ES unit based on comprehensive efficiencies (Strategy I) or capacities of the ES unit (Strategy II). Table 3 represents the evaluation indicators of each ES unit in a two-hour dispatch period with different strategies.
