摘要 大力发展可再生能源是应对能源危机和环境问题的重要手段,高比例可再生能源并网将成为未来电力系统的基本特征。文中从高比例可再生能源接入带来的强不确定性和高度电力电子化带来的稳定机理变化两个方面,分析了高比例可再生能源电力系统面临的关键科学问题。在此基础上,从中国未来电力系统结构形态分析与电力预测、含高比例可再生能源的输电系统规划、含高渗透率可再生能源的配电系统规划、电力电子化电力系统稳定性分析、含高比例可再生能源交直流混联系统的优化运行等5个方面,提出了高比例可再生能源电力系统的研究框架,重点阐述了这5个方面的相互关系。最后,对未来高比例可再生能源电力系统的研究进行了总结和展望。 Vigorously developing renewable energy generation is an effective way to tackle the challenges of energy crisis and air pollution.High proportion of renewable energy integration will be one of the basic characteristics of future power systems.This paper summarizes a number of key issues for power systems with a high proportion of renewable energy generation from two aspects:the power system planning and operation under high level uncertainty and the stability mechanism of power system with massive integration of power electronic devices.On this basis,a theoretical research framework is proposed by dividing the above two scientific issues into five sub-problems:the evolution of power system structure and its forecasting model;a multi-objective planning method for AC/DC transmission network with a high proportion of renewable energy generation;the distribution system planning with a high proportion of renewable energy generation;the stability analysis of power electronics dominated power systems;the cooperative optimal operation theory of AC-DC hybrid power system with a high proportion of renewable energy generation.The relationship among the five sub-problems is described.Finally,key technologies for future power systems with a high proportion of renewable energy generation are provided and prospected.
