The influence analysis of DG on the utilization of feeder

摘要

In allusion to the lack of the method to assess feeder utilization after distributed generation(DG)accesses to the distribution network,a method is proposed to evaluate the feeder utilization.First,the confidence capacity(CC)of DG is calculated based on equal reliability principle; second,combining with load rate and capacity factor two indicators,the influence of DG on feeder utilization is analyzed from the perspective of CC; finally,taking improved IEEE-RBTS-BUS6 subsystem as an example to evaluate the corresponding impact,the results show that DG can improve the utilization level of the feeder.
