Optimization Method of Cascade Hydro-Solar Hybrid Power Generation considering Pumped Storage Power Station and DC Transmission

Cascade hydro-solar hybrid power generation is a hot spot in recent research, a cascade hydro-solar hybrid power generation model considering pumped storage power station and DC external transmission is constructed, with the target of greatest power generation, the operation characteristics of cascade hydropower station, pumped storage power station and DC link are analyzed, and the systemic new energy utilization capacity is fully explored. Finally, through the study of the case, it is shown that the pumped storage station improves the regulation capacity of the system and promotes the consumption of new energy. Furthermore, the influence of the maximum adjustable power of DC link on the system is studied, and the optimal adjustable number is given based on the case, which verifies the feasibility and rationality of the model.
