This article focuses on mountainous photovoltaic (PV) power stations as the research subject. An automated layout model for these power stations is developed based on the TIN algorithm for contour-to-grid terrain modeling
integrated with scanning line and terrain projection algorithms. Additionally
a shadow occlusion and power generation simulation model is constructed using the polygon (W-A) clipping algorithm and the Perez model. This study analyzes terrain data from a mountainous area in Chongqing
demonstrating that the automated layout algorithm effectively resolves the challenge of transforming the multi-faceted layout of triangular grids into a single-faceted layout. Furthermore
the proposed shadow occlusion
irradiance
and power generation models are compared with PVsyst simulation results. The maximum shadow occlusion error is 0.52%
the average irradiance error is 1%
and the annual power generation error is 0.83%. With a power generation deviation of less than 5%
the results indicate that the method presented in this study is highly accurate.
