Evaluation of Electric Vehicle Hosting Capacity in Campus Microgrid Using Monte Carlo Simulation

The electric vehicle and electric vehicle charger market is rapidly growing due to increased interest in carbon free. When a lot of electric vehicles and chargers are penetrated into the distribution network, various problems such as voltage drop may occur. Therefore, it is essential to accurately determine the hosting capacity of electric vehicles from the point of view of system operation. Electric vehicles have a variety of uncertainties, including arrival and departure times, state of charge and selection of charging station. To evaluate the hosting capacity of electric vehicles, these uncertainties must be taken into account. In this paper, load modeling was performed considering the uncertainty of electric vehicle, and the hosting capacity of electric vehicle was evaluated using monte carlo simulation. In addition, load modeling was performed using the actual power consumption data of buildings in Seoul National University. The network was modeled using the parameters of the actually embedded cable. Based on the modeled data, the hosting capacity was evaluated by assuming an electric vehicle based on the actual vehicle access data.
