Optimal Planning of Charging and Power Delivering from/to the Network for Electric Vehicles Considering Types of Trip

Abstract

Abstract-In this paper, a new model is proposed for optimal planning of daily charging and power delivering from/to the power system considering time schedule of trips for electric vehicles. In this model, trips are categorized in job, shopping, educational, and pleasure and possible times to charge/injection are considered based on type of trip and limitations of charging stations. In the optimal planning, it is assumed the hourly electricity price is known and also the rate of charging is fast. The load curve of system and also charging costs are analyzed which are important for system operator and car owners, respectively. Simulation results show by using the proposed planning for time scheduling of charge/injection, a smoother load curve is obtained and the costs of customer are decreased.
