摘要

This article addresses power quality improvement in a 3-Φ grid-connected photovoltaic-fuel cell based hybrid system using hybrid filter topology. In the context of the extraction of maximum power due to the uncertainty of solar insolation and temperature in the hybrid system, backstepping control is addressed for the DC-DC boost converter. A space vector pulse-width modulation control technique is implemented for the voltage source inverter for the grid integration objective. Compensation of the distorted waveform at the point of common coupling is accomplished by a suitable controller design using the hybrid filter. The series of simulation results in MAT-LAB environment (The MathWorks, Natick, Massachusetts, USA) followed by prototype experimental validation reflects the superiority of the proposed controllers to achieve power quality improvements.
