Hybridization of Solar PV Configurations for Maximum Power Extraction Under Partial Shading Conditions

Abstract

ABSTRACT In the current era, the solar-based energy demand is exponentially progressing, because of its streamlinedness towards the environment. However, an optimized version of the photo voltaic (PV) configuration is required even though there are conventional PV configurations. In the purview of an optimized PV system, vital factors that affect the performance of the PV system are the type of configuration, partial shaded conditions, the efficiency of the PV array and power conditioning units. In this paper, an optimized configuration of a PV array under different partial shaded conditions is taken as a focal point. Therefore, a hybrid configuration of the PV system has been designed for extracting maximum power, such as Bridge Link with Triple Tied Cross Link (BL-TTCL), Honey Comb with Triple Tied Cross-Link (HC-TTCL), etc. The proposed hybrid configurations are simulated in MATLAB/SIMULINK software. The performance analysis of proposed hybrid PV configurations was analysed with the conventional configurations in terms of global maximum power point, local maximum power point, open circuit voltage, short circuit current, mismatch losses, voltage and current at maximum power point and efficiency. The outcome of both conventional and hybrid PV configurations reveals that, more cross ties result in optimized PV configurations under various partial shaded conditions due to more bypass paths, but there should be trade-off/balance between capex and technical behaviour. Therefore, the hybrid configurations balance cross ties and behaviour under various partial shaded conditions.
