摘　　要：环境经济调度是电力系统中非常重要的优化问题,随着风电并网容量的不断增加,有必要在环境经济调度中考虑风电的不确定性,为此,需建立适用于风电并网电力系统的环境经济调度模型。除了传统的因素,该模型在经济效益和环境保护两方面分别表述由于低估或高估风电出力而引起的惩罚、备用因素。同时利用风速与风能的关系推导出风电出力的统计特征,进而完成模型的确定性转化。通过对电力系统的仿真模拟发现:(1)当风电场归其他发电集团所有时,电力系统的最优计划出力高度依赖于惩罚成本系数、备用成本系数及惩罚排放系数,而对备用排放系数则没有显著影响。(2)当风电场归电网所有时,电力系统的最优计划出力高度依赖于惩罚成本系数、惩罚排放系数,而对备用成本系数、备用排放系数则没有显著影响。Economic emission dispatch（ EED） is an important optimization problem in electric power system.With rapid capacity growth of wind power on grid operation,uncertainties of wind power should be added in the EED problem.This paper presents a model to solve the EED problem including wind power.Besides the classic EED factors,the factors accounting for overestimation and underestimation of available wind power in both economic and environmental aspects are specially considered.To deduce the deterministic model,the statistical characteristic of available wind power is determined based on the feature of wind speed.With the help of MATLAB optimizing toolbox,the optimization problem is solved by a scenario consisting of two conventional generators and two wind-powered generators.The simulation results are as follows：（ 1） If the wind farm is owned by the other power system,the allocation of system generation capacity may be influenced by multipliers related to the cost and emissions for underestimation of available wind power,and by the multiplier related to the cost for overestimation of available wind power.Nevertheless,the multiplier related to the emissions for overestimation of available wind power has little impact on the allocation.（ 2） If the power system possesses the wind farm,the allocation of system generation capacity may be influenced by multipliers related to the cost and emissions for underestimation of available wind power.Nevertheless,multipliers related to the cost and emissions for overestimation of available wind power have little impact on the allocation.
