Abstract
This study delves into the comprehensive process encompassing the automated design and performance simulation of Building Integrated Photovoltaic （BIPV） power plants. An automatic module layout method has been developed based on the computer graphics scan line filling algorithm. Additionally a shadow analysis model tailored to power plants has been constructed utilizing the projection method and Boolean polygon operations. The electricity generation simulation employs the Perez model, the five-parameter model, and the SUNDIA inverter model, respectively addressing the Radiation calculation, DC power generation calculation, and power conversion processes of photovoltaic modules. To appraise the feasibility of the proposed approach, the design methodology was applied to the automated arrangement of BIPV components within a designated scenario. Results reveal marked improvements in design efficiency and effectiveness. Further, to verify the accuracy and precision of the methods, a comparative analysis was conducted between the methodology presented herein and PVsyst for the same scenario. The disparity in annual electricity generation predictions between the two approaches was found to be approximately 0.922%, substantiating the high accuracy of the proposed method.
