Multi-Scale Optimal Dispatch of Power System with Pumped Storage Units Considering New Energy Uncertainty

The uneven power output and geographically dislocated distribution due to the endowment of scenic resources are the most important problems facing the solution of new energy consumption at present. In order to improve the system capacity and operational reliability of new energy consumption, this paper proposes a multi-scale coordinated and optimal scheduling strategy for power systems with pumped storage units considering new energy uncertainty. Firstly, a day-ahead scheduling scheme is developed, and then the system prediction errors are further compensated by intra-day rolling and real-time corrections, and the constructed model can effectively improve the system capacity of new energy consumption.
