Abstract
In response to the climate change, it has been becoming the consensus of most countries in the world to accelerate the development of a high proportion of clean energy. The power grid is the core to support the development of a high proportion of clean energy, and the key is to accelerate the construction of clean power grids. This paper focuses on the main characteristics of clean power grid construction, and proposes a set of clean power grid development evaluation indicators including 5 first-level indicators and 19 second-level indicators and an analysis method based on radar charts. Taking China Power Grid as an example, this paper analyzes in detail the characteristics of the medium and long-term development mode of clean power grids and the relative change trends of specific indicators, and discusses the key links and potential problems that need attention in the development of clean power grids.

Summary
In September 2020, Chinese President Xi Jinping solemnly promised at the General Debate of the 75th United Nations General Assembly that China will scale up its Intended Nationally Determined Contributions by adopting more vigorous policies and measures, and aim to have CO2 emissions peak before 2030 and achieve carbon neutrality before 2060 [1]. Some studies have shown [2] that accelerating the development of clean power is the key to promoting energy transition, and achieving carbon emissions peak and carbon neutrality. Some scholars have carried out relevant researches on the evaluation of the development of clean power grids. Wang et al [4] selected 8 key indicators that are universal and can comprehensively reflect the overall development and operation and management level of the power grid, built a world-wide key indicator database to quantitatively evaluate the power grid and determine the interval of first-class level of the international power grid. Yang et al [6] proposed a comprehensive evaluation standard including 22 indicators involving energy, economy, environment, technology and society. Existing researches focused on the power grid or clean energy itself, and the constructed evaluation index system cannot effectively describe the characteristics of
