Abstract
This paper inspect the difficulties that result from the existing environment, which is
characterized by the thriving use of solar photovoltaic (PV) power and a rising demand for EV
grid integration. Voltage stability, reactive power compensation and grid synchronization are
crucial and become more apparent as PV systems add electricity to the grid and EVs consume
power. This study investigates the use of proportional-integral (PI) control techniques to evolve
an integrated controller that can effectively handle PV synchronization, Voltage control and
reactive power compensation when using electric vehicles. The study integrate multicarrier space
vector pulse width modulation (SVPWM) with PI control on the grid-connected converter
through a dual-control loop system dedicated to PV grid synchronization, with one loop
specifically managing EV battery charging control. It can be noted that due to the nonlinear load
and the EV integrated to the grid the load voltage is obtained. But due to the injection current
from the inverter the current at the grid is sinusoidal in nature thus controlling the reactive power
at the grid. The output obtained after the voltage regulation loop added in the dq controller
voltage and the current are to be stable at the grid. A comprehensive evaluation of the suggested
controller's efficacy is conducted using a MATLAB Simulink model that depict the PV-EV-Grid
configuration. In the end, this research provides innovative answers to the problems arising from
the integration of PV and the use of EVs, which will increase the performance and dependability
of sustainable energy systems.
