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.

Description

technical field [0001] The present invention relates to the technical field of distribution network photovoltaic fluctuation stabilization, and more specifically, relates to a photovoltaic power regulation method, device, equipment and computer-readable storage medium. Background technique [0002] With the decrease of traditional energy sources and the increasingly prominent environmental problems, vigorously developing and utilizing renewable energy sources has become a basic national policy of our country. Among them, photovoltaic power generation is one of the ideal sustainable energy sources, which has the characteristics of no pollution, no noise, safety and reliability. [0003] In the distribution network system containing photovoltaic power generation, the output of the photovoltaic power generation system is greatly affected by the climate, and the output power presents complex fluctuation characteristics, and the fluctuation of output power will affect the distrib...
