Key Technologies and Research Framework for the Power and Energy Balance Analysis in New-Type Power Systems

中文摘要英文摘要

随着新型电力系统加速构建,可再生能源发电装机与电量占比不断攀升.如何在源荷双重强不确定性下实现准确、高效、实用的电力电量平衡分析,是新型电力系统调控与规划中的基础与关键问题.通过对电力电量平衡分析在研究对象、分析模型与方法、评价指标与应用等方面的综述,总结了现有研究在平衡状态刻画和分析计算方面的不足.针对"强随机性与策略性下的电力电量平衡状态刻画"与"集中调控-协调自治平衡机制下的电力电量平衡分析与计算"两大关键科学问题,首先提出了涵盖"平衡边界生成-平衡分析计算-平衡状态评估-平衡预警-平衡能力提升"的新型电力系统电力电量平衡分析研究内容体系,接着阐述随机性平衡场景生成、多周期协调解耦的平衡分析、平衡状态评估指标体系设计、多时空分级平衡能力预警和新型平衡协作机制的研究思路与技术方案.最后总结并展望了新型电力系统电力电量平衡分析研究中需要重点突破的关键技术.

With the accelerated construction of new types of power systems,the proportion of integrated renewable energy sources has increased rapidly. Achieving an accurate,efficient,and practical power balance analysis under strong uncertainty of the source and load is a basic theme in the dispatching,controlling,and planning of new power systems. Hence,the shortcomings of current research in the description and calculation of the balance state are reviewed by summarizing the research objects,analytical models and methods,evaluation indices,and applications of power and quantity balance analyses. Based on the two key scientific issues of "electric power and energy balance state description under strong randomness and strategy" and "electric power and energy balance analysis and calculation under the centralized regulation-coordination autonomous balancing mechanism," a research theoretical system for electric power and energy balance is proposed. First,this system covers "balance boundary generation-balance analysis and calculation-balance state assessment-balance early warning-balance capacity improvement." Then,research ideas and technical schemes are proposed,including random balanced scenario generation,multi-period coordination decoupling balanced analysis,balanced state evaluation index system design,multi-spatial-temporal hierarchical balanced early warning,and balanced cooperation mechanism construction. Finally,some key technologies are worthy of consideration in further research on electric power and energy balance analyses in new types of power systems.
