摘要
Based on the very high penetration of renewable energy into distribution system, the supply mode and impact that penetration of distributed generations has on the reliability analysis are studied. On the basis of building the model of photovoltaic power, wind power, energy storage batteries and the load containing domestic electrical vehicle piles, the supply mode with the center of distributed generations, failure effect analysis and power matching strategy are proposed, and the algorithm of reliability assessment is designed based on sequential Monte Carlo stochastic simulation method. The reliability assessment is realized on the improved IEEE RBTS Bus2 system using the proposed models and algorithm. The reliability indexes in the block supply mode are given by case analysis, and the influences of different kinds of renewable energy on reliability indexes are compared, which can provide reference for the reliability analysis and source planning of distribution systems with very high penetration distributed generations.
