Implementation of Multifunctional Electric Vehicle Charger Based on ANFIS with Solar PV Array
摘要
This article describes the development of a grid-connected, home-based electric vehicle (EV) charger that meets the demands of an EV, household loads, and the grid. The charger is powered by solar photovoltaic (PV) arrays. The charger is built inside a solar panel array so it may operate independently while providing uninterruptible power and charging home loads. Nonetheless, the grid linked mode of operation is possible if there is no or inadequate PV array generation. Synchronization and smooth mode switching management assist the charger, enabling automatic grid connection and disengagement without interfering with household supplies or EV charging. In order to maintain local loads, the charger also offers active/reactive power assistance from V2G and power transfer from V2H. Moreover, the charger is set to operate as an active power filter, keeping the grid current's total harmonic distortion (THD) to less than 5% and maintaining a unity power factor (UPF). An adaptive neuro-fuzzy inference system (ANFIS) is utilised to regulate the dc-link voltage as part of an energy management method that is based on dc-link voltage regulation. The sinusoidal reference grid current is supplied by a second-order generalised integrator frequency locked loop with dc offset rejection (SOGI-FLL-DR) for efficient operation under distorted voltage settings.
