Evaluation of impact of integrated distributed generation on distribution network based on time-series analysis

This paper presents comprehensive quantification indices to evaluate the influences of distributed generation (DG) integration on distribution network from three aspects, which involve voltage quality, economics and hosting capacity. Based on the modified IEEE 13-nodes test system, the time-series power flow analysis of DG integration is carried out for duration of one day. The proposed indices are calculated and analyzed according to the different time-series simulation scenarios to evaluate the different DG integration cases, which has the great theoretical and practical significance for the development and application of DG integration.
