Building a New Electric Power System Based on New Energy Sources

构建以新能源为主体的新型电力系统,既是我国电力系统转型升级的重要方向,也是实现碳达峰、碳中和目标的关键途径。本文分析了电力系统转型带来的变化、问题及挑战,阐述了新型电力系统的内涵、构建原则与思路;根据电力系统发展的技术特征、新能源接入规模,合理划分新型电力系统的发展阶段并针对性提出各阶段的发展建议。研究认为,新型电力系统以新能源为电能供给主体,可满足不断增长的清洁用电需求,兼具高度的安全性、开放性、适应性;相关系统构建是一项系统性工程,应遵循电力系统的技术演进规律与特征,充分利用成熟技术、存量系统并深入挖掘潜力,同步着力研发新兴技术,积极稳妥并循序渐进实施重大转型。

Building a new electric power system that is based on new energy sources is an important direction for power system transformation and upgrading in China,and it is critical for peaking carbon emissions and achieving carbon neutrality.In this study,we analyze the changes and challenges that are brought by power system transformation and elaborate on the connotation and building principles of a new electric power system.Moreover,we categorize the development of the new system into stages and propose development suggestions for each stage considering the technical features of the system and the new energy access scale.The new electric power system proposed in this study can satisfy the increasing demand for clean power as it primarily uses new energy sources and it has the features of high safety,openness,and adaptability.Building the new electric power system should follow the technical evolution law and characteristics of power systems;it should further exploit the potentials of mature technologies and current power systems.Meanwhile,emerging technologies should be researched and developed.
