Active Power Dispatching Model of Power System after Large-scale Wind Power Grid Connection
In order to ensure stable operation of power system after large-scale wind power grid connection,and solve the prob-lems of poor scheduling effect and high scheduling cost in the existing active power scheduling model,optimal design of power system active power scheduling model is carried out.The large-scale wind power scenario is selected as the dispatching range of active power,the wind power grid connection process is simulated in this scenario,and the impact on the power system after grid connection is analyzed.According to the extraction results of power time series characteristics and power flow calculation results of power system,the active power value of power system is predicted.The active power scheduling of power system af-ter large-scale wind power grid connection is completed through the steps of power distribution,scheduling calculation and con-straint setting.Through the example application analysis and experiment,it is concluded that compared with the traditional scheduling model,the active power output obtained by using the designed scheduling model is closer to the expected value,and the scheduling cost is reduced by 27 000 yuan.
