Abstract:
Environmental/Economic Power Dispatch (EED) now is one of the critical issues in power systems.Aiming at the nonlinear fuel cost function and particle emission function which take generation unit’s real power generation amount as decision variable,the generation unit is transformed into a fuzzy variable and a novel fuzzy multiobjects model for EED is proposed to replace the traditional quadratic programming model.Furthermore,an improved genetic algorithm is adopted to find out the optimal solutions.Finally,the effectiveness of the method is testified by the simulations on an IEEE 3generator test system,and the result shows the cost of power system and particle emission amount are greatly reduced.
