A novel control strategy for power extraction from photo voltaic panels based on One Cycle Control

Abstract

This paper presents maximum power point tracking and load voltage regulation of a photo voltaic panel using One Cycle Control (OCC). The power generation by renewable energy sources depends highly on atmospheric conditions and due to that they are very chaostic in nature. Hence rapid control becomes an essential requirement for the converters used for power conditioning. Conventionally PI controller is used for the control of power electronic circuits employed in such systems. But conventional PI controller takes few switching cycles to track the variations in operating conditions while the one cycle controller can track them within one switching cycle. Also compared to PI, OCC has a better transient response. Short current pulse based maximum power point tracking is used here to compare the performance of OCC and PI controller. MATLAB/Simulink simulation results are provided to verify their performance.
