Risk Assessment of Distribution Network Involving Fault Outage Economic Losses
摘要
Abstract
With reference to the transmission grid safety assessment methods and the consideration of the difference be-tween the transmission grid and the distribution network,a novel risk assessment method of distribution network based on the fault outage economic losses is proposed. Firstly,according to the characteristics of the distribution network,its structure is appropriately simplified,and the distribution network is partitioned with various types of switches as bound-aries. Secondly,by adopting the customer survey method,the unit power economic losses of different kinds of power us-ers is obtained. Based on linear correlation analysis,the corresponding loss functions are fitted by using least square method. Finally,according to the theory of risk assessment,the risk values of each region,sectionalizing switch and the whole feeder are calculated by regarding each region and all kinds of switches as evaluation units and the outage eco-nomic losses as severity. The weak link in the distribution network can be found through the risk values. With the feeder 5 of IEEE-RBTS as an example to verify the proposed assessment method,the results show that the risk values have def-inite physical meaning,which can accurately locate the weak points in the distribution network and provide reference for the scheduling department.关键词
