Optimal economic dispatch for wind farm considering uncertainty of wind power

Abstract

Because of the wind power generation characteristics, the wind turbine’s dispatch model is based on wind power prediction. Even though the current average forecast error of ultra-short-term wind power prediction is already low, there are still some errors and uncertainties. Therefore, the scenario analysis method is used to estimate the forecast error. The deterministic modeling is realized by using the spare amount. In order to plan the operating cost of the wind farm reasonably, the scenario analysis method and the possible spare cost are combined with the idle cost of the unit to establish an economic dispatch model within the wind farm. The example analysis shows that the model is feasible.
