摘要
传统集中式调度方法难以满足高渗透率分布式电能资源接入背景下电力系统经济调度的需求,分布式经济调度方案因具有可靠性高、可扩展性强、通信计算负载均匀等特点得到了越来越多的关注。对电力系统分布式经济调度方法的国内外研究现状进行了综述,重点阐述了一致性算法的原理、应用及成为分布式经济调度主导算法的原因。比较了集中式和分布式经济调度系统及问题的求解过程,分析了分布式经济调度实现过程的关键环节,并对现有关键问题解决方法的优缺点进行了评述,分析了电力系统分布式经济调度方法研究中有待解决的问题并提出了未来可进一步研究的方向。
Traditional centralized dispatch methods are unable to meet the needs of power system economic dispatch in the context of high-permeability distributed energy resource access. Distributed economic dispatch scheme has received more and more attention due to its characteristics of high reliability,strong scalability and uniform communication and computation burden. The research statuses of distributed economic dispatch methods at home and abroad are reviewed. The principle and application of consensus algorithm and the reason why it becomes the dominant algorithm of distributed economic dispatch are emphasized.The centralized and distributed economic dispatch system and the problem solving process are compared.The points of the distributed economic dispatch process are analyzed,and both advantages and disadvantages of the existing methods are reviewed. The problems to be solved in the study of distributed economic dispatch method are analyzed and the possible further research directions are proposed.
