Design of a PV‐fed electric vehicle charging station with a combination of droop and master‐slave control strategy

Abstract

AbstractElectric vehicles (EVs) are becoming essential elements for both the transport and power sectors. Consequently, they need a suitable charging infrastructure at the same time. Electric vehicle charging stations (EVCS) assisted by photovoltaic (PV) panels draw attention due to minimal expenditure, increased environmental awareness, and a consistent increase in the effectiveness of the PV modules. In this paper, a combination control scheme utilizing the merits of both droop and master‐control strategies for the EVCS is proposed. In addition, an isolated bidirectional DC‐DC converter combined with the snubber circuits and a three‐level boost converter that utilizes a capacitance‐voltage control design is used to further enhance the system stability. The design of the EVCS is formulated and validated through MATLAB/Simulink.
