Dynamic Modeling and Eigen Analysis of Adjustable-Speed Pumped Storage Unit in Pumping Mode Under Power Regulation
The main merit of grid-connected adjustable-speed pumped storage unit (ASPSU) is the capability to control the pumping power flexibly, which contributes to active power balance in power system operation.Physics-based dynamic modeling of ASPSU in pumping mode under power regulation is the foundation of the quantitative analysis on its transient perf
