Pv Off Grid System with Improved Charge Controller Using Closed Loop Control

Abstract

A photovoltaic (PV) off grid system is a cutting-edge energy system that harnesses solar power to provide reliable electricity to localized areas. This abstract focuses on enhancing the performance of PV standalone off grid systems through the implementation of an advanced charge controller employing closed-loop control strategies. These autonomous energy systems, powered by solar panels, offer a decentralized solution to electricity generation and distribution. Traditional charge controllers may not efficiently adapt to varying solar irradiance levels, leading to suboptimal energy harvesting. The closed-loop control system proposed in this work addresses the need for dynamically adjusting the charging algorithm in response to real-time environmental conditions, ensuring maximum energy captured from the PV system. The open circuit voltage algorithm plays a pivotal role in increasing the overall efficiency of the PV micro grid. By responding intelligently to changes in solar irradiance and load requirements, the system minimizes energy losses and maximizes the utilization of available renewable resources, thereby addressing the need for efficient energy management. The results obtained from MATLAB simulation are compared with other methods in terms of maximum power efficiency. The results suggest that the open circuit voltage algorithm is efficient.
