Photovoltaic power adjustment method, device, equipment and medium

Abstract

The invention discloses a photovoltaic power adjustment method, a photovoltaic power adjustment device, photovoltaic power adjustment equipment and a computer readable storage medium. The photovoltaicpower adjustment method comprises the steps of: calculating output power of a photovoltaic power station at each prediction point; calculating a target output power value of the photovoltaic power station during a prediction period according to the output power of each prediction point, and an operating state and power data of an FSC variable speed pumped storage unit; calculating a power instruction value of the FSC variable speed pumped storage unit according to the target output power value, real-time power of the photovoltaic power station and the power data of an FSC variable speed pumped storage unit; and transmitting the power instruction value to the FSC variable speed pumped storage unit, so that the FSC variable speed pumped storage unit stabilizes the photovoltaic power stationfor one time. The photovoltaic power adjustment method, the photovoltaic power adjustment device and the photovoltaic power adjustment equipment utilize the rapid adjustment capability of active power of the FSC variable speed pumped storage unit to stabilize the output power of the photovoltaic power station for one time, so as to obtain relatively smooth output power, thereby reducing the fluctuations of the output power.
