同步电网发展趋势与中国能源互联网发展研究

在“清洁替代、电能替代”的能源发展趋势下，电网作为输送与分配电能的载体，是能源供应体系的重要组成部分，是现代经济发展和社会进步的重要基础和保障，更是能源互联网的核心主体。通过对北美、欧洲和俄罗斯等典型电网百余年发展的研究，总结了世界典型同步电网发展从传统电网到现代电网，从孤立电网到跨区、跨国大型互联的一般规律，为中国电网的发展提供借鉴。基于对中国电网发展历程和考虑新能源特性电网互联演化的分析，结合电力需求、能源开发以及电力流规模的发展趋势，提出了基于同步电网格局的中国能源互联网未来的发展形态，为构建全球能源互联网奠定重要基础。

Synchronous Power Grid Development Trend and China's Energy Interconnection Development

In the energy development trend of 'clean energy replacement and electricity replacement'， as the carrier for transmission and distribution of electric energy， power grid is an important part of the energy supply system， and the important foundation and guarantee of the modern economic development and social progress， moreover is the core subject of energy Internet. This paper analyzes the history of power grids in North America， Europe， and Russia over hundred year history， and summarizes the general development rule of typical synchronous power grids in the world from traditional grid to modern power grid， isolated grid to interregional and international large-scale interconnected grid， which provides references for the development of China's power grid. Based on the analysis of China power grid development history and the study of power grid interconnection evolution feature integrating renewable energy features， this paper proposes the future development patterns of China's energy interconnection based on the synchronous grid framework， combining the electric power demand， the energy exploration， and the development trend of electricity flow scale， which can be an important foundation for the construction of the global energy internet.
