Economic Dispatch of Power System Considering the Prediction Error of Wind Power, Solar Energy and Load
摘要
Abstract
To deal with the uncertainties of wind power,solar energy and load,the uncertainties of prediction error is introduced,and an optimal model of economic dispatch of power system based on uncertain programming theory is pro?posed,in which the prediction error of wind power,solar energy and load is considered. Firstly,different probabilistic distribution characteristics of wind power,solar energy and load are analyzed. Because of their different characteristics, fuzzy variable and random variable are employed respectively. On the basis of the above analysis,environmental pollut?ant cost and the output cost of wind power,solar energy and load are comprehensively considered,and a multi-objec?tive processing strategy of fuzzy comprehensive evaluation based on analytic hierarchy process is applied. A mixed simu?lation evolutionary algorithm is applied to solve the model based on economic dispatch. The results show the rationality and effectiveness of the proposed model.关键词
