Integrating large scale of wind power into power grid poses new challenges to the traditional economic dispatch （ED）. A multi-objective dynamic economic dispatch model considering the operating cost of fossil fired units and wind farms, the discharging cost of pollution, and the cost of reserve is formulated. The up spinning reserve and the down spinning reserve constraints are included to deal with the influence of wind power＇s waviness on ED. According to the analytic hierarchy process （AHP）, the multi-objective objective optimization model is transformed to a single objective optimization mod
