Study of Regional Pathway to Carbon Peak in Electric Power Section

Abstract

China has announced the dual carbon targets in 2020, to achieve carbon peak before 2030 and neutralization by 2060. Many studies have forecasted the structures of China's energy as well as pathways and measures. Considering the characteristics of electric power system and the electrification development, this study proposed an assessment strategy to analyze the applicability of pathways to electric carbon peak in a region. Taking a certain region for an example, this paper comes up with two scenarios, high imported power and high nuclear capacity, by using the optimization model. Then, it compares these two pathways through evaluating the economic efficiency, reliability and security of power system, and carbon targets. Though lower cost per kWh of high nuclear scenario, taking into account the power system reliability and total carbon emission level, a high receiving ratio of power is a better choice for this certain region.
