“…At present, most of the research on the PSU participating in system frequency regulation uses PSU as an auxiliary means and does not play a role in a large amount of energy storage. The literature [13] proposed a method for pumped storage units to participate in the system automatic power generation control and frequency regulation operation, which realized the step change of output power by changing the operation state of pumped storage units to realize the pumped storage units auxiliary thermal power units to participate in the system frequency control, but did not explain the advantages and economic benefits of pumped storage units auxiliary thermal power units to participate in the system frequency control. The literature [14][15][16] established a simulation model of the combined wind-fire-storage multi-source system in Simulink, and verified that the pumped storage unit-assisted thermal unit, which can smoothly regulate the fluctuation of wind power and stochastic power output, has a better effect on frequency control for the dynamic situation of load change.…”

Facing the challenges of grid stability brought by the large-scale access of new energy to the grid, as one of the important means of frequency regulation of the grid, the doubly-fed pumped-storage units (DFPSU) have great practical significance in the study of the joint frequency regulation strategy with the thermal power unit (TPU). In order to reduce the frequency regulation pressure on the grid caused by the large-scale entry of new energy sources, this paper proposes a joint frequency regulation strategy for the TPU and DFPSU. Based on establishing the optimal scheduling model of the system, taking into account the minimum total operating cost and the optimal time as goals, the chaotic particle swarm optimization (CPSO) is proposed to solve the model. Finally, through MATLAB simulation, the relevant examples are studied and analyzed, and the simulation results verify that the joint frequency regulation strategy in this paper can effectively improve the frequency regulation performance of the unit and the operation economy is good.
