[0022] Step 1: Establish a generalized power output model, and set the distributed power model (wind power and photovoltaic), energy storage system model and controllable load model with independent control strategies. figure 2 It is a partial schematic diagram of a substation in the power supply area, indicating the position of GPS in the station;
[0023] (1) Distributed Power Modeling
[0024] The relationship between wind turbine output and wind speed is expressed as follows:
[0025] (1)
[0026] In the formula: v ci , v r , v co and P r are the cut-in wind speed, rated wind speed, cut-out wind speed and rated power of the wind turbine, respectively, f ( v ) is the wind speed at v ci and v co When between, the functional relationship between the wind speed of the wind turbine and the wind power;
[0027] The relationship between the active output of photovoltaic power generation system and the intensity of solar radiation:
