Abstract: The development of traditional PV plant is nowadays strongly limited by the scarcity of land resource, which greatly hinders the development of photovoltaic technology, how to solve the land resources shortage problem becomes urgent in PV industry. The floating PV power station can solve the problems of land resources shortage produced by traditional PV power station and becomes a competitive investments area. How to ensure the dynamic stability of the floating foundation, the most important part of the floating PV power station, under various wind-wave conditions is a concern. We use the finite element to study the floating foundation dynamic stability under different waves. The results show that the four corner areas of the floating foundation are load concentrated and should be payed attention to in design and operation, and this phenomenon is also verified by practical project, which proves the feasibility of the method.

Key words: surface floating PV power station, floating foundation, dynamic stability, wave load, finite element analysis
