Study on Wind Power Development with Support of Pumped Storage

In view of the accelerated development of wind power and other renewable energy, this paper adopts power optimization planning model with the objective of minimized total system cost, and considers the technical and economic characteristics of various power supply units. The paper systematically studies the impact of the construction of pumped storage power stations on improving the accommodation of wind generations in the provincial level power grid and system operation efficiency. By constructing a multi-scenario comparison plan, the differences in power installation, power balance, peak shaving balance, and typical daily unit operating positions are compared and analyzed, and a power system power expansion optimization plan for a certain province by 2025 is given.
