Stochastic Power Flow Simulation of Microgrid Considering the Correlation of Wind Power Output
The randomness and correlation of wind speed affect the distribution of power flow in microgrid.Stochastic power flow simulation technology is an effective method to study such problems.Based on the analysis of the correlation of wind speed and wind power,copula function is used to model the correlative wind speed,and the sampling wind speed are transformed into wind power through power curve.The wind turbine model and the power flow calculation model are iterated alternately to simulate the microgrid stochastic power flow.Finally,the stochastic power flow of microgrid is simulated by an example,and the influences of wind speed randomness and correlation on the stochastic power flow are revealed.The simulation results can provide the basis for developing dispatching strategy.
