电源绿色发展指数研究

Green Development Index of Power Supply

在电力系统中,电源规划建设工作举足轻重,为进一步探究各类电源的可持续发展空间,分别选取典型工程,采用生命周期评价方法(life cycle assessment,LCA)建立投入产出清单,提出了针对电力系统中不同发电方式评价的绿色发展指数模型,其涵盖能源、资源、环境三大维度,并拓展考虑到电源土地占有情况、保证出力及其他效益。通过燃煤火电、水电、风电及光伏发电典型工程应用,计算得到A—H典型电站绿色发展指数依次为0.34,0.35,0.83,0.45,0.41,0.46,0.21和0.26,指数较高的C、D、E、F电站所对应电源则为此次方案下更适合进一步发展的对象。研究中所建立的电源绿色发展指数理念和模型,可为今后既定方案下电源的开发选择提供有效的理论支持。

In power system construction,power source planning is significant. In order to explore the further sustainable development space of different types of power sources,selecting typical projects respectively,this paper adopts life cycle assessment(LCA） method to establish the input-output inventory,and proposes the green development index model for different power generations,which covers energy,resources and environment in three dimensions and takes into account the land occupation,output guarantee and other benefits. Through the typical engineering application of thermal power,hydropower,wind power and photovoltaic power generation,the green development index of A-H power station is 0. 34,0. 35,0. 83,0. 45,0. 41,0. 46,0. 21 and 0. 26 respectively. Power stations with higher indices correspond to just like C,D,E and F is the object for the further development under this scheme. The idea and model of the green development index of power supply may provide useful theoretical support for the development and selection of power supply in the future.
