A Three-Stage of Charging Power Allocation for Electric Two-Wheeler Charging Stations

Abstract

In developing countries as well as in Vietnam, infrastructure for two-wheeled electric vehicles is necessary but has not drawn much attention. Sustainable transportation in urban traffic requires sustainable solutions to first-mile/last-mile services which are essential for eco-friendly and efficient connection to the public transport system. Hence, electric two-wheeler charging stations which coordinate charging a large number of electric bicycles/electric motorcycles at public parking or transit hubs should be considered. In this study, the authors propose a novel approach to effectively allocate power to electric two-wheelers in a charging station which is interconnected with the distribution grid, a photovoltaic system and conventional loads of a building. With a three-stage of allocation, the proposed algorithm proves its effectiveness in reducing load variance as well as peak shaving and valley filling while relieving the complexity of solving multivariable optimal problems. The idea also contributes to increasing the penetration rate of both electric vehicles and distributed photovoltaic sources while alleviating adverse effects of these emergent factors.
