提出了计及风力发电影响的配电系统可靠性评估的一种新方法.该方法基于网络分块简化技术和伪序贯蒙特卡洛模拟(PSMC)技术,能快速准确地进行系统可靠性计算.基于分块简化网络,通过系统的两种故障影响矩阵,可以快捷地确定出故障发生后各网络分块的供电恢复情况.伪序贯蒙特卡洛模拟方法是系统可靠性评估的一种混合方法,其中对系统状态进行非序贯蒙特卡洛抽样,而仅对描述整个停电过程的故障相邻状态子序列进行序贯蒙特卡洛模拟,这样既保留了非序贯蒙特卡洛模拟的计算效率,又能模拟系统中风电随机功率输出、时变负荷等时序事件.最后,对 IEEE RBTS 系统不同情况下的系统可靠性水平进行了对比分析,其结果验证了所提方法的有效性和实用性.

This paper presents a new method to evaluation reliability of distribution system considering wind power effect. The proposed technique is based on the combination of segment-network simplification and pseudo sequential Monte Carlo simulation, which can calculate the system reliability indices quickly and accurately. After the segment-network is obtained, two failure effect matrixes of system are proposed which can rapidly determine the service restore process of all the segments. Pseudo sequential Monte Carlo simulation is a hybrid method for reliability evaluation in which non-sequential simulation is used to select failure states and sequential simulation is applied only to the subsequence of neighboring states that define the complete interruption. The pseudo sequential simulation retains the computational efficiency of non sequential simulation and the ability to model the chronological aspects. At last, system reliability indices of IEEE RBTS system are compared and analyzed; the results demonstrate the validity and practicability of the proposed method.
