Design and implementation of photovoltaic system using hill climbing MPPT algorithm

This paper explores the benefits of distributed power electronics in solar photovoltaic applications through the use of PV module integrated maximum power point trackers (MPPT). We propose a system architecture that provides a fast and conditionally stable maximum power Point tracking scheme with high tracking efficiency is proposed for photovoltaic applications. The provides linearly increased in capturing energy during shading conditions, while at the same time improving the efficiency with reduced cost. This is achieved through the method of hill climbing MPPT technique used in power converters. We describe the design and implementation of a high-efficiency DC-DC boost MPPT converter, along with digital control techniques that ensure both local and global maximum power extraction. Through detailed experimental measurements under real-world conditions, we verify the increase in energy capture and quantify the benefits of the architecture.
