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 hybrid energy storage system combined with coal fired thermal power plant in order to support frequency regulation project integrates the advantages of “fast charging and discharging” of flywheel battery and “robustness” of lithium battery, which not only expands the total system capacity, but also improves the battery durability.
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 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.
The energy storage system generating-side contribution is to enhance the wind plant's grid-friendly order to transport wind power in ways that can be operated such as traditional power stations. It must also be operated to make the best use of the restricted transmission rate. 3.2.2. ESS to assist system frequency regulation
The coupling coordinated frequency regulation control strategy of thermal power unit-flywheel energy storage system is designed to give full play to the advantages of flywheel energy storage system, improve the frequency regulation effect and effectively slow down the action of thermal power unit.
