Concerning dual-carbon applications, establishing a new energy-dominated power system to achieve carbon peaking and carbon neutrality objectives is imperative. Pumped storage units excel in this context, owing to their unique advantages. During the load-shedding process of the pump turbine, the intricate flow patterns and cavitation phenomena substantially influence the …
The transition processes of PSGS refers to twenty-four switching operations (Fig. 1), therein, condenser mode to generating, as one of the typical transition process, is attracting more concerns in scholars and industrials than other transition process.This is mainly because PSGS utilizes the condenser mode to regulate voltage, balance active & reactive power, …
The pumped storage system need to regulate its load dramatically and may conduct bidirectional operation, which brings challenges to pumped storage systems in transient operation [24, 25]. How to improve the transient performance of pumped storage systems especially during large fluctuation process urgently needs to be researched. Therefore ...
