Abstract

The invention discloses a photovoltaic and pumped storage coordination control method, which is applied to a coordination control process of a variable-speed pumped storage power station and a photovoltaic power station, and comprises the following steps: acquiring millisecond-level regulation performance data and minute-level regulation performance data of the variable-speed pumped storage power station; acquiring real-time photovoltaic output data of the photovoltaic power station; according to the real-time photovoltaic output data, the millisecond-level regulation performance data and the minute-level regulation performance data, an actual power regulation mode is automatically selected in a power regulation mode set; the power regulation mode set comprises a millisecond-level power regulation mode, a minute-level power regulation mode and a combined power regulation mode. Through the technical scheme of the invention, the stability and smoothness of light storage power output can be improved, the quality of electric energy output by light storage combined output is improved, and the impact of new energy access on a power grid is reduced.

Description

technical field [0001] The present application relates to the technical field of multi-energy complementation, and in particular, to a method and system for coordinated control of photovoltaics and pumped hydro energy. Background technique [0002] Renewable energy power generation has important strategic significance in alleviating the pressure of global warming, energy shortage and environmental pollution. Vigorously developing renewable energy has become an important way to solve the global energy crisis and achieve the dual carbon goal. Renewable energy sources such as photovoltaics and wind power have the characteristics of randomness and volatility. [0003] Pumped storage power station is currently the most mature technology, the largest commercialized energy storage power generation system with good cost performance, and the operation of photovoltaic and other renewable energy combined with pumped storage power station is an effective way to promote new energy consum...
