摘要(Abstract):
文中探讨概率潮流计算在电力系统规划设计和运行方式研究中的应用。提出了在随机潮流计算中设置电压控制节点的概念和方法 ,可用来分析节点电压随机波动对系统其他节点电压和支路潮流的影响。对于电压控制节点 ,还可以计算出无功注入功率的随机分布 ,并由此确定在这些节点上应配置的无功补偿设备容量。通过计算实例验证了算法有效性和准确性
The application of probabilistic load flow analysis in power system planning and operation are investigated in this paper.The conception and method of setting voltage control nodes and lines due to the disturbs of some nodes voltage are given.In the voltage control nodes,the stochastic distribution of reacˉtive power injection can be calculated.On the basis of the distribution the capacity of the node reactive power compensation can be determined.The validity and accuracy of the algorithm are demonstrated by a case study in the paper.
