Study and control of a pumped storage hydropower system dedicated to renewable energy resources

Abstract

The pumped storage hydropower systems are benefits for grid reliability and integration of variable renewable energy, in this context this paper presents the study and control strategy of a pumped storage hydropower (PSH) system based on permanent magnet synchronous machine (PMSM) associated to the renewable energy source. The dynamic behavior of a pump-turbine, including the PMSM with high number of poles, the AC/DC converter and the control of this system, is studied. Also, a control method of the PSH system, which consists of the reversible pump-turbine unit entrained by the PMSM, supplied of the variable power renewable energy source through a power electronic converter. Simulation results obtained on the basis of the dynamic models of the pump-turbine are given, for different operating points, to demonstrate the performance of the proposed system.
