Modeling of Electric Vehicles as Movable Loads in Composite System Reliability Assessment

摘要

This paper proposes an approach to construct a load profile for electric vehicles (EVs) in composite system reliability analysis considering drivers' behavior in terms of charging time and location. As EVs are movable loads, the amount of load demand at system buses dynamically changes based on the drivers' behavior. Therefore, the charging pattern of EVs reshapes power system load profile which impacts power system reliability. In this work, the constructed load profile of EVs is combined with the system load profile to evaluate system reliability indices. The well-known composite system reliability indices are evaluated for different charging locations. The proposed method is demonstrated on the IEEE Reliability Test System through several case studies. Monte Carlo simulation is used to evaluate the composite system reliability indices.
