[0066] Such as figure 1 As shown, a refined prediction method for regional power supply load based on two-stage restoration includes the following steps. Step 1: collect regional electricity load P L,d , small hydrothermal power generation power P S,d , New energy power generation power P N,d and regional mutual supply power P H,d The historical data and the time-sharing and zone temperature T d , rainfall H d , solar irradiance I d and wind speed V d historical and forecast data. Where d∈{1,...,D}, D is the total number of historical sample days.
[0067] Step 2: Using the two-stage reduction method, the network supply load P W,d Decomposed into regional electricity load P L,d and small hydrothermal power generation power P S,d , new energy generation power P N,d and regional mutual supply power P H,d The combination:
[0068] P W,d =P L,d -P S,d -P N,d -P H,d (d=1,2,...,D)
[0069] Step 3: Obtain the forecast results of various types of load curves based o...
