Abstract

Abstract:

As the charging of electric vehicles is full of randomness and complexity， the large-scale application of electric vehicles is bound to bring a series of problems to the distribution network， which has become the research hotspot in the domestic and foreign scholars and research institutions. Based on a large number of the measured data on charging load of electric vehicles， choose the charging start time and duration of the charging as two key factors affecting the time distribution of charging load， combined with the analysis of the uncertainty of user charging behavior， build time distribution model of charging load of electric vehicles. According to this， divide the charging load area and the time and space distribution model of electric vehicle charging load was established. Through the example analysis， the impact of charging load of electric vehicle on the voltage drop， power loss and load curve of local distribution network was researched.

Key words: electric vehicle, temporal and spatial distribution, uncertainty analysis, distribution network operation
