Performance Analysis of PV Arrays under Different Shading Conditions

EasyChair Preprint 5846

Abstract

In order to fight climate change, investors, policy-makers, and power producers around the world are focusing on decreasing the share of generation from fossil fuels and increasing the share of renewable energy generation, especially through harnessing abundantly available solar energy. However, the power output and reliability of the photovoltaic (PV) plants are affected due to partial shading to great extent. This paper investigates the effect of in-creasing the interconnection redundancy in the PV array, in mitigative the power loss under different partial shading conditions in MATLAB® platform. The analysis revealed that the configuration with no interconnection redundancy (i.e., a series parallel array) and with fill redundancy (i.e., a total cross-tied array) performs equally well under uniform irradiance and under self-shading created by low altitude sun, e.g., during sun rise and sun set, when the distance between adjacent rows is inadequate. In case of all other shading scenarios, such as shading created by nearby buildings, trees, poles and non-uniform dust accumulation, increase in the interconnection redundancy increases the performance ratio of the PV plant.
