Power Quality Improvement For PV/Battery Hybrid System Using Fuzzy Logic Controlling Technique
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2015, Vol 3, Issue 12
Abstract
power quality improvement for pv/battery hybrid system using fuzzy logic controlling technique has been presented this paper. The PV side cascaded boost DC-DC converter is controlled by P&O algorithm to extract the maximum power from the solar irradiation. The battery energy storage system (BESS) is regulated to balance the power between PV generation and utility grid. In this paper a modified Instantaneous symmetrical components theory has been presented to the μG-VSC in micro-grid applications (i) to feed the generated active power in proportional to irradiation levels into the grid (ii) compensation of the reactive power, (iii) load balancing and (iv) mitigation of current harmonics, thus enabling the grid to supply only sinusoidal current at unity power factor. A new fuzzy logic control technique is also proposed in this paper for the battery converter with DC link voltage regulation capability. The dynamic performance of battery is improved with fuzzy logic controller, and shows the better performance compared with conventional method. A model of a hybrid PV Energy Conversion System is designed in MATLAB/SIMULINK software to test the effectiveness of the proposed control strategies.
