Design and Simulation of A Single Current Sensor Maximum Power Point Tracker for Solar Hydrogen System

Abstract

Abstract. Renewable energy sources have attracted a lot of research interest in the past decade. Among these, solar energy is regarded as one of the promising energy sources and has been deployed worldwide with the installed capacity continually increasing. Solar-hydrogen systems have been under research for more than two decades. In such system, maximum power point tracking (MPPT) plays an important role to deliver maximum power from solar panels to the electrolyser. In this paper, two simple but effective MPPT methods are developed and evaluated. Differed from most of the existing methods, these methods are only reliant on a single current sensor input to locate the maximum power point of the solar panel.
