随着电网运行环境日趋复杂,各区域间相互影响不断加深,通过多区域协同控制技术实现区域间备用共享、提升区域协同控制水平已成为国内外的研究热点。文中阐明了协同控制的具体概念和驱动力,介绍了国内外相关应用技术的基本控制结构;从电网频率和联络线功率两个控制目标,分别介绍了目前协同控制应用技术的现状;在评述各种方法的基础上,提出了目前存在的主要问题,并展望了可能改进的方向。
With the increasing complexity of power grid operating environment and the deepening of mutual influence among regions, it has become a research hotspot both at home and abroad to realize inter-region backup sharing through multi-region coordinated control technology. The paper describes the concept and driving force of collaborative control, and introduces the basic control structure of relevant application technologies at home and abroad. According to the control objectives of grid frequency and tie line power, the current status of application of collaborative control technology are introduced respectively. Based on the above methods, the main problems that exist at present are put forward and the possible directions for improvement are prospected.
