Construction of an Evaluation Index System for Assessing Performances of the New Power System Demonstration Zones

In 2021, China initiated the construction of the New Power System to accelerate the development of renewable energy and accommodate its "3060" goal. This New Power System aims to ensure energy security while meeting the demands of economic and social development. It features four key characteristics: safety and efficiency, cleanliness and low emissions, flexibility and adaptability, and intelligent integration. The objective of the New Power System has been separated into three strategic phases: accelerated transformation phase (up to 2030), overall formation phase (2030 to 2045), and consolidation phase (2045 to 2060). To study the feasibility of the system, several regions have been selected as pioneers to build small-scale demonstration systems. Thus, the development and evaluation of these demonstration projects play a crucial role in promoting the system on a much larger scale. This paper proposes a simplified evaluation framework based on the Analytic Hierarchy Process (AHP) method, emphasizing key indicators that reflect the core traits of the new power system, such as sustainability, reliability, efficiency, and flexibility. The proposed framework is tested in one of the demonstration zones in Guangdong Province, demonstrating its practicality and effectiveness in evaluating the performance of the power system.
