Abstract

The application discloses a kind of photovoltaic power station capacity matching ratio calculation method and device.The calculation method can realize: by the first set and the second set are crossed combination and obtain the multiple combination numbers of coupling multi-factor, and coupling is obtained in the total power generation of each combination number corresponding preset period in combination with the two major influencing factors of the electric parameter of energy storage system and the light abandonment quantity of photovoltaic power station, the calculation precision of the total power generation of each combination number corresponding preset period can be improved by the coupling effect of multi-factor, in turn be favorable to improve the calculation precision of subsequent capacity matching ratio.And according to the total power generation of each combination number corresponding preset period of higher calculation precision and preset index, target combination number meeting preset index condition can be accurately screened, so as to accurately determine capacity matching ratio according to target combination number, in turn ensure the rationality of capacity configuration, improve the income of photovoltaic power station installation energy storage, improve on-grid power.
