摘要
"双碳"目标下,新能源发电占比的不断升高和用电需求的持续增长,严重影响了电力系统供需平衡.居民负荷以体量大、响应快速和控制灵活的特点,逐渐成为发挥电力系统灵活调控能力的重要资源之一,是近几年研究关注的热点.文章结合国内外最新研究成果,从居民负荷的调控机制、可调节特性、调控策略及应用场景4个方面对居民负荷参与电力系统调控的关键技术进行综述,重点比较了用于生成最优调控策略的多种算法以及居民负荷参与调控的多样化场景.最后,针对现阶段实施调控过程中面临的实际挑战,提出了信息-物理-社会系统视角下的居民负荷调控市场机制建设、调节能力精准快速感知,以及弱通信环境下调控策略优化与执行等重点问题,并对未来研究方向进行了展望.
Abstract
Under the goal of carbon peaking and carbon neutrality,the increasing proportion of renewable energy generation and the continuous growth of electrical demand have affected the supply and demand balance of the power system significantly.Residential loads,characterized by their large quantities,fast response speeds and flexible control capabilities,have gradually become an important resource to facilitate the power system's dispatch and control capability and have become a hot research topic in recent years.This paper investigates the latest research results and summarizes the key technologies for residential loads participating in power system dispatch and control from four aspects:the control mechanism,adjustable characteristics,control strategies and application scenarios.The optimization algorithms to generate control strategies and the multiple dispatch and control scenarios in which residential loads can participate are compared in detail.To address the practical challenges faced by the present implementation of residential load dispatch,this paper highlights the key issues including market mechanism construction,fast and precise perception of adjustable capability,as well as the optimization and execution of control strategies in weak communication environments under the framework of cyber-physical-social system.Finally,prospects are made for future research directions.
