【摘要】：含微网配电系统的可靠性评估中,为保证结果的收敛,蒙特卡洛模拟法需消耗大量的仿真时间。针对耗时问题,提出了一种基于储能多状态模型的可靠性评估算法。该算法首先建立了微网净功率多状态模型和储能SOC值的多状态模型。其次,为了评估孤岛微网的负荷停电情况,提出了孤岛后果分析的定义以及孤岛后果分析的方法。然后,基于两多状态模型和微网的孤岛后果分析,提出了一种适用于含微网配电系统的可靠性评估算法。最后,算例分析表明在保证精度的同时,本算法能节约90%的仿真时间。此外,算例还对本算法的收敛性和实用性进行了分析。
[Abstract]:In the reliability evaluation of the micro-grid power distribution system, in order to ensure the convergence of the results, the Monte-Carlo simulation method needs to consume a large amount of simulation time. In view of the time-consuming problem, a reliability evaluation algorithm based on energy-storage multi-state model is proposed. The algorithm first establishes a multi-state model of the net power multi-state model and the energy storage SOC value of the micro-net. Secondly, in order to evaluate the load power failure of the island micro-network, the definition of the island consequence analysis and the method of the island consequence analysis are put forward. Then, based on the two-state model and the island consequence analysis of the micro-network, a reliability evaluation algorithm for the micro-network power distribution system is proposed. Finally, an example shows that the algorithm can save 90% of the simulation time while the accuracy is guaranteed. In addition, the convergence and practicability of the algorithm are also analyzed.
