The improvement on simulation model of charging station

Abstract

To study the harmonic current of charging station, the paper improved the original simulation model of charging station by adding the control methods of charger operation and building charging station parameter component, which is based on the custom function of the PSCAD / EMTDC. By using the improved simulation model, we could change the number of charger, access time of charger, output power of charger, initial capacity of rechargeable battery in different cases. In addition, the paper predicted access time of charger in the morning based on investigative results of working time. The initial capacity of rechargeable battery was 20%-40% of total capacity in random. As a result, the paper forecasted the operation of the charging station and studied the characteristics of harmonic current of the charging station in the morning. © 2012 Springer-Verlag.
