摘要

In order to solve the problem of peak shaving capacity in power system caused by high permeability of renewable energy, this paper proposed a cascaded hydropower "Virtual pumped storage power station" scheduling method. The "Virtual pumped storage power station" model of cascade hydropower stations is established by studying the coupling relationship between each cascaded hydropower stations, simulating the operation of pumped storage power stations from both hydraulic and electrical aspects. Under the constraints of cascaded hydropower stations, the objective function of peak shaving power of "virtual pumped power station" is constructed and figured out. The simulation results prove that the cascaded hydropower scheduling from this method is able to significantly improve flexibility and economy of cascaded hydropower, and taps the peak shaving potential of cascaded hydropower sufficiently.
