Reliability Assessment on Distribution Cyber Physical System Considering Distributed Generation
摘要
Abstract
Large-scale distributed generation(DG)and the corresponding information communication system will be in?tegrated into the distribution grid in the future. However,the volatility of DG output and the uncertainties related to the cyber system will exert a negative impact on the safe and reliable operation of power grid. In this paper,a reliability as?sessment method for the distribution cyber physical system(CPS)is proposed considering DG. First,the support role of cyber system and the effect of its failure are analyzed in post-fault scenarios,respectively. Then,a fault tree model is es?tablished for off-grid failure considering the influence of cyber system on the operation from the grid-connected mode to the islanded mode. Moreover,considering the volatility of DG output,the time-sequence process of CPS is simulated by means of sequential Monte Carlo method to evaluate the effect of cyber failure on the distribution CPS. Finally ,compara?tive analysis is conducted at different penetration levels of DG. The results of a case study show the effectiveness of the proposed method,and it is suggested that the system reliability can be improved by increasing the DG capacity.关键词
