Low carbon Economic Dispatch of Power System Integrated with Wind Farms by Considering Uncertainties Factors

Because of the uncertainty of the price of carbon trading, carbon trading is introduced in dispatching system integrated with wind power system, which increases the number of uncertain factors. In view of the multiple uncertainties of low carbon economic dispatching, in this paper, according to their different characteristics and their different influence on the dispatching system, wind power forecast error and load forecast error are expressed as fuzzy variables and random variables, and a hybrid chance constrained condition is used to consider its influence on spinning reserve of dispatching system. According to carbon trading price volatility model, multiple scenarios technology is used to establish low carbon dispatching model by considering the carbon trading price fluctuation. The model is solved through the determining of the unit on/off status and the dispatching of unit power output, and the optimal power output is determined under the optimal unit on/off status by using scenario evaluation index. A ten unit test system is used to verify the rationality and effectiveness of proposed model.
