摘要

Abstract

The front-row shading reduction coefficient is a key parameter used to calculate the system efficiency of a photovoltaic (PV) power station. Based on the Hay anisotropic sky scattering model

the variation rule of solar radiation intensity on the surface of the PV array during the shaded period is simulated

combined with the voltage–current characteristics of the PV modules

and the shadow occlusion operating mode of the PV array is modeled. A method for calculating the loss coefficient of front shadow occlusion based on the division of the PV cell string unit and Hay anisotropic sky scattering model is proposed. This algorithm can accurately evaluate the degree of influence of the PV array layout

wiring mode

array spacing

PV module specifications

and solar radiation on PV power station system efficiency. It provides a basis for optimizing the PV array layout

reducing system loss

and improving PV system efficiency.
