POWER PLANT POWER SYSTEM AND POWER CONTROL METHOD THEREFOR

The invention provides a power station electric power system and a power control method of the power station electric power system, the power station electric power system comprises a power station controller, a power station voltage transformation unit, a direct current conversion unit and an inversion unit, and the alternating current end of the inversion unit is coupled and connected to the power station voltage transformation unit in parallel. And the direct current end of any inverter unit is coupled with the maximum power point tracking MPPT controllers of the plurality of direct current conversion units. And the power station controller obtains the active capacity and the reactive capacity of the power station based on the active capacity and the reactive capacity of each inversion unit obtained by the target MPPT controller coupled with each inversion unit. And the power station controller performs reactive power control on each inversion unit based on the power station active capacity, the power stat
