摘　　要： 针对传统发电权交易在追求经济效益和环保效益最大化的过程中,机组有功出力的改变势必对系统安全稳定运行带来一定风险的问题,提出一种以静态电压稳定裕度、系统能耗降低比例和线路阻塞为约束,以系统有功网损、能源消耗量和CO_2排放成本最小为目标的发电权交易多目标优化模型,采用约束松弛变量策略的中心校正内点算法对该模型进行求解,并选取IEEE30标准节点系统为例,进行多目标发电权交易优化测试,分析了该系统发电权交易后的绩效性、节能环保性和安全性,验证了算法的正确性及所提模型的有效性。 In the process of maximization economic benefits and environmental benefits for the traditional generation right transaction,unit power output change will bring certain risks to the stability and security of the system problem.Considering the stability margin of static voltage,reduction ratio of energy consumption and line congestion as constraints,multi-objective optimization model of generation rights trade was proposed by taking active power loss,minimum energy consumption and CO_2 emission cost as the objective functions.The proposed model was solved by centrality correction interior point method based constrained slack variables strategy.The IEEE30 standard node system was selected as an example to test the optimization of multi-objective generation right transaction.The economy,energy saving,environmental protection and safety of the system were analyzed.The correctness of the algorithm and the effectiveness of the proposed model were verified by the example results.
