Evaluation on Operation Security of Distribution Network with Distributed Generation Based on Hybrid Weighting
摘要
Abstract
Accessing of distributed generation (DG)will have a series of effects on safe operation of the distribution net-work. Therefore,this paper firstly analyzes influence of DG on security of the distribution network and then discusses short-ages in traditional security analysis method for the distribution network. In aspects of equipment security,state security and load security,it establishes security index system for distribution network operation considering influence of DG. A projec-tion pursuit method based on entropy is presented for constructing projection objective function and ensuring dispersion of projection values and stability of projection direction. According to the least square criteria,subjective weight is used for rectifying projection vector and finishing hybrid weighting. Combining with actual feeder line data of Qingdao distribution network,reasonability of the security evaluation index system and method is verified and results indicate this system and method are both correct and reliable.关键词
