Abstract

The Electric Vehicles (EVs) are garnering immense attention in recent times, since they support sustainable transportation with minimized carbon emission. The amount of carbon footprint released to the atmosphere is further reduced with the adoption of Photovoltaic (PV) based EVs. The PV output is initially fed to a DC-DC SEPIC converter, which produces high dc voltage with non-inverting output and reduced switching loss. The operation of the SEPIC converter is controlled using a Hybrid Grey Wolf Optimization (GWO)-Particle Swarm Optimization (PSO) based Proportional Integral (PI) controller for providing a stable DC voltage to the three phase Voltage Source Inverter ( 3𝜑 VSI). The 3𝜑 VSI output is used to power the BLDC motor of the EV. The power from the PV is sufficient for the EV application during daytime, however, during night time with the absence of the sun, the BLDC motor is supplied with the power from the grid. The grid is connected to this system through a Single Phase (1 𝜑 ) VSI. The proposed control method is verified using MATLAB simulation and the hybrid GWO-PSO algorithm delivers an outstanding efficiency of 96%.

基于Sepic变换器的并网电动汽车混合优化Pi控制器性能分析

电动汽车(ev)最近受到了极大的关注，因为它们支持可持续交通，同时将碳排放降至最低。由于采用了基于光伏(PV)的电动汽车，排放到大气中的碳足迹量进一步减少。PV输出最初被馈送到dc - dc SEPIC转换器，该转换器产生高直流电压，无反相输出，减少开关损耗。采用混合灰狼优化(GWO)-粒子群优化(PSO)的比例积分(PI)控制器控制SEPIC变换器的运行，为三相电压源逆变器(3 -变量VSI)提供稳定的直流电压。3个变量的VSI输出用于为电动汽车的无刷直流电机供电。来自PV的功率在白天足以满足EV的应用，然而，在没有太阳的夜间，无刷直流电机由电网供电。网格通过单相(1变量)VSI连接到该系统。通过MATLAB仿真验证了所提控制方法的有效性，结果表明该混合算法的控制效率高达96%。
