摘要
The uncertainty in the temporal and spatial distribution of electric vehicle's (EV) charging load will directly affect the network's load pattern and other operational characteristics. This paper analyses the key factors which can affect the EV's charging load. Based on the data obtained from the EV charging terminals of a technology park in Beijing, the EV charging's starting time, duration and charging power are analyzed in terms of their probability distribution and probability density function. EV load's temporal and spatial probability representation and the charging load's expected model are then analyzed. Using Beijing area's summer load as a case study, the EV's unregulated charging and its effect to the distribution network's load characteristic is analyzed under different EV penetration levels.
