INTEGRATION OF MULTIPLE ENERGY SOURCES IN A GRID-TIED CHARGING STATION WITH INTELLIGENT FEEDBACK CONTROL FOR LINEAR AND NON-LINEAR LOADS

Control and Instrumentation Engineering

The development of electric vehicles (EVs) has led to an increased need for charging stations that are not only efficient but also environmentally friendly. One approach is to use renewable energy sources such as solar or wind power to charge EVs. However, these sources can be intermittent, and there is a need for efficient and reliable power management systems that can integrate multiple sources of power to charge EVs. This project aims to address the challenges of integrating multiple sources of power for charging EVs while ensuring high power quality with reduced harmonic distortion This aims to develop a system that combines multiple power sources using a novel four-leg inverter and feed them into the grid with both linear and non-linear loads. AC supply that acts as a charging station for electric vehicles and it is given to a PFC converter that is controlled by a PI controller. Another input source battery converter is also fed into the system. The multiple power sources are then combined using a four-leg inverter that is controlled by an ANN based feedback line controller with DQ theory transformation. The system ensures that the power fed into the grid is of high quality with reduced harmonic distortion. This project has potential applications in industrial, commercial, and residential power systems where multiple power sources are required to be integrated into the grid. The entire work for enhancing charging capacity of the EV through improved MS is carried out in MATLAB 2021 and simulation responses are obtained.
