Abstract
Disclosed are a photovoltaic power plant and a primary frequency modulation control method therefor. The photovoltaic power plant comprises a photovoltaic power plant and an active power control system. The photovoltaic power plant comprises a photovoltaic array and a photovoltaic inverter, the photovoltaic inverter converting direct current electric energy generated by the photovoltaic array into alternating current electric energy. The active power control system is used for determining the variable quantity of active power of a single machine according to an operating state of the photovoltaic inverter when frequency values of grid connection points of the photovoltaic power plant meet a pre-set primary frequency modulation triggering condition, and regulating the active power output by the photovoltaic inverter. According to the disclosed photovoltaic power, the response speed and accuracy of primary frequency modulation of a generator set can be improved.
