In the novel power systems,an integrated system of“source-network-load”is estabilshed,and a further analysis of the novel power system is usually needed.This paper proposes a novel method to analyze the output characteristics and source-load characteristics for new power systems.Firstly,a novel power data evaluation standars is established,and then a procedure for source and load data’s intergration is realized,so that it can describe the features of various scenarios precisely under different time scales.Experimental results on a realworld wind-photovoltaic-load charge system show that the proposed method can evaluate the novel power systems’characteristics effectively.Therefore,it can improve the performance of planning and actual operation in the novel power systems.
