The stability of floating photovoltaic structures is one of the critical issues constraining the development of offshore floating photovoltaic. Currently
there is a lack of research on the stability of multi-floating photovoltaic arrays
particularly regarding the influence mechanism of connector stiffness on system dynamic response under combined wind and wave action. This study explores the impact mechanism of connector stiffness on the dynamic response of multi-floating photovoltaic arrays under combined wind and wave action based on potential flow theory
utilizing AWQA numerical simulation technology. A single/double-floating-body photovoltaic power station of the pontoon-support type was selected as the research object. The equations of motion for the hinged multi-floating photovoltaic in moored and articulated linkage states were constructed. Comprehensive numerical calculations and analyses were performed on the six degrees of freedom motion of the multi-floating bodies.The effect of connector stiffness on the motion response and mooring force of the double-floating-body photovoltaic system under different wind-wave incidence angles was studied. The results indicate that as the stiffness of the floating body connection increases
the motion response decreases. Setting the connector stiffness appropriately can significantly enhance the stability of the floating photovoltaic platform
reducing motion amplitude
and the optimization reference values for stiffness are proposed.
