Abstract: The Drainage Services Department of the Government of the Hong Kong Special Administrative Region of the People's Republic of China has implemented floating photovoltaic (FPV) systems to enhance the utilization of renewable energy and minimize greenhouse gas emissions. Given that Hong Kong is prone to typhoon occurrences during summer, it is crucial to investigate the stability of FPV systems under extreme weather conditions. This paper aims to study the robustness of FPV systems under adverse weather conditions. Field measurements of wave and wind data were conducted in 2023, to study the environmental conditions for the two pilot FPV systems situated at the San Tin Polder and Shing Mun River. The European Centre for Medium-Range Weather Forecasts (ECMWF) was used to drive the coupled hydrodynamic-wave models Delft3D-FLOW and SWAN (Simulating Waves Nearshore). The models were validated with field data. Simulated hydrodynamic and wave conditions were then applied in the CFD model OpenFOAM to calculate the dynamic responses and mooring forces of the FPV system. The stability of the system under extreme waves, high flows, and strong winds was analyzed, demonstrating the robustness of the FPV design to withstand extreme weather. These findings offer valuable insights for optimizing FPV design and improving the cost-effectiveness of future FPV projects.
