Analysis of Multiple Source Load Characteristics and Its Impact on the Distribution Network

The high proportion of multiple source load connections has become a prominent feature of the current distribution network development. An accurate quantitative analysis of the impact of multiple source loads on the distribution network, so as to ensure the safe and stable operation of the distribution network, is a problem that needs to be solved urgently. In this paper, a method is proposed to analyse the characteristics of multiple source loads and their impact on the distribution network. Firstly, the characteristics of multiple source loads in the distribution network are analysed; secondly, a method is proposed to analyse the spatio-temporal characteristics and correlation of multiple source loads, based on the Copula theory to analyse the correlation of multiple source loads; secondly, a method is proposed to analyse the impact of multiple source loads on the technical indexes of the distribution network to quantify the impact caused by the grid connection of multiple source loads; finally, an example analysis is used to verify Finally, the validity of the proposed method is verified by using case studies.
