Power Supply Reliability Analysis on Floating Photovoltaic Systems through Exceedance Probability Approach

Abstract

With the growing impact caused by the greenhouse gasses (GHG) emissions from traditional thermal power generation, solar energy has drawn much attention from governments in recent years. Constrained by the land factor, the Taiwan Energy Bureau released the “Photovoltaic Two-Year Promotion Plan” on September 8, 2016 to promote the Floating Photovoltaic (FPV) industry. After that, the Agondian Reservoir FPV became the first successful commercial project. In this paper, the authors proposed a synthesis approach based on the exceedance probability approach to conduct the FPV reliability analysis. The case analysis results show that this paper's proposal is feasible. The plan's implementation will obtain the effect of CO2 emission reduction of approximately 1,920 kt (kilo tons) in 20 years. The presented methodology may help evaluate the power supply reliability, reduce failures of FPV systems that have been installed or will install, and assist in extending the FPV system to areas with insufficient power but water bodies.
