Abstract
This study evaluated the design and performance of an improved 3.5 MW floating photovoltaic (PV) power generation system consisting of fiber-reinforced polymer (FRP) members and its installation in the ash pond of a thermal power plant. The FRP design code of the American Society of Civil Engineers was used to design the structure. The safety of the structure was then confirmed using a finite element analysis indicating that the induced stresses were less than the allowable stresses dictated by the Korean Highway Bridge Design Code. An examination of the energy performance of the floating PV energy generation system after installation determined that the measured electricity production was as high as approximately 94% of the installed 3.5-MW capacity. The energy production of the floating PV structure with the improved design and module angles was found to increase by 7.65 times.
Highlights
Energy costs are rapidly increasing in many countries due to fossil fuel depletion, continuously high oil prices, and imbalances between supply and demand
Among the different types of renewable energies, photovoltaic (PV) power generation has been included in the Renewable Portfolio Standard (RPS) system since
Class floating PV power generation complex is constructed using fiber-reinforced polymer (FRP) members, the total cost for the structures is 2.77 times lower than for those shown in Figure 2a and and 2.48
Summary
Energy costs are rapidly increasing in many countries due to fossil fuel depletion, continuously high oil prices, and imbalances between supply and demand. In South Korea, steel, aluminum, and FRP have all been used as structural materials in floating installations since 2009. When a 3.5-MW class floating PV power generation complex is constructed using FRP members, the total cost for the structures is 2.77 times lower than for those shown in Figure 2a and and 2.48. In Korea, asTotal there no clear design standard for a floating PV3510,000 generation system,1410,833 clearly evaluating the load on such structures is difficult. To evaluate theto the parameters forchanges installation the unused surface a thermal power analysis plant ash pond in Dangjin-si, proposed to the on floating we of used a finite element to model its Chungcheongnam-do, Korea
