摘要：Large-scale integration of wind power has brought profound challenge to traditional power generation dispatch.It becomes necessary to effectively coordinate the operation of wind power and traditional power sources.Traditional economic dispatch to minimize the fuel cost no longer meets the need for environmental protectionwhen emission reduction is mandatory. Based on the optimal dispatch in traditional power system, theconcept of “energy-environmental efficiency” was introduced to modify the optimal dispatch model in windpower integrated system, and the multi-objective optimal dispatch model was proposed on the basis ofcomprehensively considering the minimum of the resource consumption, the best energy-environmentalefficiency and the highest system stability. A hybrid particle swarm and simulated annealing optimizationalgorithm with fuzzy technology was presented to solve the optimization model. Compared with traditionaleconomic dispatch, the model proposed in this paper is reasonable and can better protect the ecologicalenvironment.
