Abstract:

Renewable power utilization has become an essential requirement for the power grid system, replacing conventional fossil fuel generation. Power extraction from renewable sources is a complex task as the power generation is variable due to unpredictable natural sources. In this paper, an HTFB DC/DC converter is connected to a PV array for extracting maximum power. The HTFB is operated by a high-frequency pulse for the power electronic switches on the primary side of the converter. The duty ratio of these pulses is controlled by the MPPT technique, which takes references from PV voltage and current signals. A traditional INC MPPT is used for maximum power extraction from the PV array. This MPPT technique is updated to FLC MPPT for better stability and improved power extraction from the PV array. For testing and comparing these techniques, a grid connected inverter with an EV charging station is adopted. The inverter injects the extracted power by the HTFB into the grid and also sharing to the EV charging station. All the comparative results are generated using the Simulink environment of MATLAB software.
