Research of optimization framework for China's Low-carbon Technology Development based on 3E model: a case study of electricity industry

Energy security and climate change are the two major challenges facing human society, it's a hot topic that how to realize comprehensive balance and coordinated development among Energy-Economy-Environment. Low-carbon technology is the key to the development of low-carbon economy, and rational planning of the development of low-carbon technology roadmap has the role of guiding low-carbon industry development. This study aims at the lowest cost on carbon emission reduction technology under the constraints of carbon emission reduction targets in all stages; establishes the framework of low-carbon technology development to make portfolio optimization based on MARKAL model; and then take electricity industry for example, and conduct Scenario Design on low-carbon technology in electricity industry by stage in order to define the best low-carbon technology roadmap of electricity industry over the next 40 years. On that basis, propose the matching policy recommendations to ensure the development of low-carbon technology roadmap. The proposed optimization framework of low-carbon technology roadmap can provide technical methods for the development of low-carbon technologies and establishment of related policies in other industries.
