Abstract

With the increase of wind and photovoltaic power generation grid scale, the anti-surge characteristics of wind power and output volatility of photovoltaic generation put forward new challenges to the safety of power grid. Moreover, the height consistency of photovoltaic output peak and load daytime trough aggravated the load pressure of power system. In this paper, the output characteristics of pumped storage units is studied to optimize the output power and boot mode of the pumped storage power station, so as to promote the consumption of wind and photovoltaic power and to participate in the power system peak shaving. In this paper, the mathematical model of peak shaving strategy of pumped storage power station combined with wind-photovoltaic power generation is written and emulate based on the Localsolver optimization tool, and the results verify the effectiveness of this optimization strategy. When the installed capacity of the pumping station is close to that of wind and photovoltaic power generation, the load curve can be well followed by adjusting the output power of pumped storage units in the premise of the complete consumption of wind and photovoltaic power generation.
