Integration of Battery Energy Storage Systems to Solar PV to Reduce the AH Capacity by Extracting Maximum Power from PV Array under Varying Irradiance and Load Conditions for Rural/Remote Area Applications

Abstract

Abstract Integration of two or more sources of energy generating units is fruitful where energy distribution by utility grid is not feasible. This paper provides the insight into design and performance analysis of a hybrid system consisting of solar Photovoltaic (PV) and battery to yield a continuous power to the load for rural/remote areas with lesser Ampere Hour (AH) capacity. The objective of this paper is to reduce the AH capacity of a battery pack by extracting the maximum power from the PV array. The performance of a proposed PV-Battery Integrated System (PBIS) under varying irradiance, load conditions has been carried out on a 4 × 1 PV array system. The performance assessment has been carried out on various parameters such as PV array, Battery, Load currents & powers, Percentage of PV power improvement etc., These results of proposed topology are compared with the solar array with bypass diode configuration under four different shading patterns. The simulation is carried out using MATLAB/SIMULINK and results are presented.
