Grid-Tied Solar Integrated Electric Vehicle Charging System with Advanced LMS Control

Electric vehicles (EVs) and energy storage systems, along with monitoring, protection, automation, and control devices & communications, present significant opportunities for realizing a sustainable energy future because of the increased penetration of renewable distributed energy resources. This article presents a solar photovoltaic (PV) array and a storage battery integrated three-phase electric vehicle charging station (EVCS), which feeds clean power to the grid using an advanced least mean square algorithm (ALMSA). This method is appropriate for an EVCS when the system is incorporated into various linear and non-linear loads in addition to the regular changes in the EV's charging and discharging. In addition to harmonic reduction, ALMS control addresses a critical control requirement. The EVCS incorporates a charging and discharging facility and functions in grid-tied and standalone modes. A bidirectional DC converter is used for EV charging and discharging. In the case of surplus PV power, EVs may deliver power based on the available state of charge, and when PV power is not present, EV batteries properly adjust the load. Additionally, to provide a smooth mode shift, the grid voltage is synchronized when the CS is connected to it. Different steady-state and dynamic situations under various operating modes are considered for demonstrating appropriate behavior.
