摘要
电力高峰负荷持续增长以及间歇式能源的迅猛发展对电力系统调节能力提出新的重大挑战,柔性负荷调度作为发电调度的补充,已成为国内外关注的热点。从柔性负荷参与电网调度运行的视角综述了近年来国内外在柔性负荷可调度潜力、调度模式、响应行为建模和调度架构等方面的研究成果,着重对比分析了不同调度模式和调度架构的适用场景和优缺点,从柔性负荷综合响应建模、多时间尺度互动交易模式、多时间尺度协调调度、集中&分布式协调控制和互动效益评估5个方面探讨了柔性负荷调度领域需进一步研究的方向。并结合中国国情,提出了开展柔性负荷调度的建议设想。
Integration of flexible and controllable load resources into power system scheduling and operation will enrich scheduling modes and enhance the system regulating capability,which has become a worldwide research hotspot.This paper is intended to make a review of recent investigations on the adjustable potential,scheduling modes,response behavior modeling and scheduling frameworks of flexible loads considering demand response DR .Then detailed light is shed on the advantages and problems of these scheduling modes and scheduling frameworks.By proceeding from five aspects including modeling of flexible load’s comprehensive response,multi-time scales interactive trading modes,multi-time scales coordinated scheduling, coordination of centralized control and decentralized control,interactive benefit assessment,further research directions for flexible load scheduling are discussed.In addition,in view of China’s actual situation,suggestions for and assumptions about developing flexible load scheduling are proposed.
