计及风电场不确定性的电力系统鲁棒优化调度OA

With the rapid development of new energy power generation,large-scale wind power has been integrated into the power grid,but the volatility and intermittency of wind power pose challenges to power system dispatching.Therefore,considering the uncertainty of wind power output,it is an important issue to construct a dispatch model that considers the uncertainty of wind power output.This paper constructs an economic dispatch model for power systems that considers the uncertainty set of wind power output.First,the forecasting interval and prediction error are used to construct the wind power output ellipsoidal uncertainty set.a reliable probability density function for wind power output is obtained,Second,according to the possible scenarios of wind power in the uncertainty set,the automatic power generation control(AGC)unit output is reasonably planned to establish to minimize the power generation cost and a robust optimized economic dispatch model that maximizes the use of wind power.Finally,through the analysis of the example,the robustness,reliability and economy of the model are verified.
