摘　　要：在分析了国内外多区域协同控制应用技术的驱动、现状与发展建议基础上,以华东电网的动态区域控制偏差(ACE)为例,针对所提出的目前多区域协同控制应用技术存在的几点问题,结合现有的应用条件阐述了其改进的方法。首先,结合理论分析与动态ACE的实际应用情况,讨论了当前动态ACE存在的一些问题;通过构建考虑断面可传输容量的备用容量计算模型,实现区域实际可传输备用容量的估算;以全网备用共享为目标,提出动态ACE的改进算法,保证各区域的调节方向保持一致;进一步结合省(市)间断面的传输裕度,提出动态ACE下发调节功率量的修正算法,结合现有的安全约束调度系统,实现对关键断面的两级协同控制。Based on analyzing the drives, state-of-the-art and proposed development of applied technology of coordinated control among multiple control areas, by taking the dynamic area control error （ACE） of East China power grid as an example, potential solutions to some problems suggested in the previous paper are reviewed. First, the basic theory and application of dynamic ACE are introduced, and the problems of dynamic ACE are discussed. Then, a calculation model for available transfer capacity of tie-lines used for estimating reserve capacity deliverable is developed, while an improved algorithm for reserve sharing is proposed to activate automatic generation control （AGC） and contingency reserve among muhiple control areas in the same direction. Furthermore, corrections considering the available transfer capacity of tie-lines between areas are proposed. The joint application of the corrected ACE method and current security constrained dispatch system provides a possible approach to hierarchical congestion management.
