Light storage vehicle park energy management method and system based on maximum demand estimation

The invention discloses a maximum demand estimation-based photovoltaic storage vehicle park energy management method and system, and the method comprises the steps: collecting photovoltaic historical data and load historical data of a photovoltaic storage vehicle park, carrying out the clustering analysis of the photovoltaic historical data and the load historical data through a preset clustering algorithm, and determining a photovoltaic-load typical day; dividing the photovoltaic-load typical day into a plurality of preset time periods, and collecting the number of electric vehicles arriving at and leaving the photovoltaic storage vehicle park in the time periods; updating the V2G resource pool of the vehicle storage park according to the number of the electric vehicles; constructing a rolling optimization model according to the photovoltaic-load typical day and the updated V2G resource pool in combination with the time-of-use electricity price and the two-part system electricity price; and performing energy
