Electric Vehicle Charging Load Calculation Considering the Limitation of Charging length

Electric vehicle is becoming popular and will become an important load on electric systems as the oil resources exhaust. Studying the charging loads of electric vehicle is of great importance when analyzing the influence of grid-connected electric vehicles on the operation of electric system. The Monte Carlo simulation technology was utilized to simulate the charging load of a single electric vehicle, with considering different charging modes of electric private cars, taxies, buses and service cars. The total charging load was subsequently obtained based on the prediction of the inventory of electric vehicles. In the simulation, considerations have been given to the starting charging time, charging mode, initial state of charge (State of charge, SOC) and uncertainty of charging time on the one hand, on the other hand the considerations of the private car have been given to the limitation of the charging time in public places.
