Type 2 Intelligent Controller for Grid-Tied Solar Electric Vehicle Charging Stations

Abstract

Electric vehicles (EVs) are becoming a popular alternative to gas-powered cars. These cars need “full” batteries to run. Solar-powered chargers are an exciting alternative to grid-based EV charging. These chargers give electric vehicles pollution-free electricity, which benefits the environment. Solar PV is the most popular renewable energy source. This chapter establishes a solar EV charging station, which charges EVs. Bi-directional batteries store photovoltaic (PV) energy for use during power outages. PV overproduction is transferred to the grid for later use. Cascaded interval type 2 fuzzy logic controller (CIT2FLC) boosts voltage using KY converter to track maximum photovoltaic power. To accomplish grid synchronization, a DC voltage is delivered to a grid-connected 1 phase VSI and optimized using a PI controller. During peak hours, EV gets power from the grid via 1 phase VSI, with the KY converter in buck mode. The suggested work ensures uninterrupted charging. The complete structure was tested using MATLAB Simulink and yielded 94.7% efficiency and 3.9% THD.
