【摘要】 随着现代工业的发展和社会的进步,能源的消耗日益剧增,随之而来的是对环境的污染和生态平衡的破坏。电力系统环境保护问题已经越来越为人们所关注。文章将火电厂的环保影响放入最优潮流中,提出一种新的目标函数权重确定方法,该方法将火电厂所处的地理位置、气象条件和影响人口综合考虑形成影响因子,并通过排放罚款将影响因子转化为具有经济意义的权重系数。利用该因子可将多目标优化问题转化为单目标优化问题,然后利用原对偶内点法对该模型进行求解。为了得到更优的结果,文章利用隶属函数将模型进行了转化,然后对传统的内点法进行了改进用以求解该多目标问题。并利用IEEE30节点系统对两种算法进行了验证。更多还原

【Abstract】 Along with the growing energy consumption of modern society,the environmental protection problem of power system is becoming more important.In this paper,the environmental impacts of thermal power plants are considered in optimal power flow,and a new method to determine the weight of objective function is proposed.Thermal power plant’s geographical location,weather conditions and the impact of population factors are taking into consideration to form a impact factor,and the factors are translated into meaningful penalty factor through the emissions fine,after that the multi-objective optimization problems been translated into a single objective optimization problem.A primal-dual interior point method is used to solve the problem.In order to obtain better results,the Membership Function is used to make a model transformation,and then the traditional interior point method has been improved to enable it to better deal with multi-objective problem.An IEEE30 bus system is used to verify the effectiveness of the algorithm.更多还原
