摘要
提出了考虑线路容量约束和潮流分布的基于序贯蒙特卡罗仿真和时变负荷模型的评估配电网可靠性的模型。模型中切负荷策略综合考虑了停电损失费用、停电电量、网损和停电时间,因而该模型在模拟配电网的故障和负荷点停电情况方面更加符合实际运行情况,并可以评估不同调度策略下的可靠性风险指标和可靠性效益指标的影响。经采用IEEERBTS配电系统测试,结果表明该模型是合理的、有效的。
Considering the power line transmission capacity and power flow distribution, a reliability evaluation system based on sequential Monte-Carlo simulation and time-varying load model is established and used to evaluate the reliability of distribution network. In the load shedding strategy the cost for the compensation caused by power supply interruption, the cost of quantity of electricity caused by power supply interruption, the network losses and the time interval of power supply interruption are comprehensively considered, therefore this model will be more actual in the simulations of the faults in distribution network and that of the situation of the power supply interruption in load points, in addition this model can be used to evaluate the risk indices and effect indices of reliability under different dispatching strategy. The test result by IEEE RBTS shows that this model is rational and effective.
