Life cycle economics of geothermal power generation system:a case study of Yangbajing project in Xizang
摘要
Abstract
Addressing the current issues of insufficient precision in the economic evaluation of geothermal power generation projects and the imperfection of the assessment system,an evaluation index system tailored for the technical and economic aspects of such projects has been established.It proposes a comprehensive life-cycle economic evaluation model for geothermal power generation projects that incorporates carbon trading considerations.Taking the Xizang binary fluid geothermal power generation project as an example,the model is applied to conduct a detailed calculation and analysis of the project′s economic performance after completion.The results show that the project′s levelized kW·h cost is 0.588 5 yuan/(kW·h),the internal rate of return is 10.94%,and the payback period is 16.12 years,which verifies the practicability and accuracy of the evaluation system in practical application.At the same time,the influence of multi-dimensional sensitivity factors such as cost,income and financing on the profitability of geothermal power generation projects is systematically analyzed to provide reference for the cost control of geothermal power generation projects.关键词
