Stochastic Dispatching of Wind Power Considering Errors of Power Prediction

Abstract

Aiming at the stochastic dispatch problem brought by wind power, the expected model of wind power considering the errors of power prediction is established according to stochastic programming theory. And the calculation steps based on Monte Carlo stochastic simulation and genetic algorithm are proposed. An IEEE 30-bus example with wind farms is given to verify the feasibility and effectiveness of the method. The result shows that the stochastic dispatch method based expected value model can quantify the uncertainty caused by the prediction error of wind power well and optimize the expected value of wind power accommodation. It plays a positive role in improving dispatching level and promoting wind power accommodation.
