摘要： 研究并提出计及城市电网不同类型负荷可靠性要求和事故风险的在线预防控制协调决策方法，适用于负荷特性多样、功能区可靠性要求差异化的大型城市电网。分析城市电网发展对事故预控提出的新需求和现有防御手段的不足，在此基础上，给出计及措施代价和事故风险的预防控制协调决策模型，进一步通过措施枚举组合、集群迭代计算的方式实现分区负荷转移和馈供用户优化减负荷方案搜索，为大型城市电网精细化、差异化和一体化事故防御奠定基础。利用实际电网运行数据进行仿真分析，验证方法的正确性和可行性。

关键词: 预防控制, 大型城市电网, 分区负荷转移, 减负荷措施

Abstract: An on-line preventive control coordinated decision-making method is proposed considering different types of load reliability demands and accident risks in urban power grid, which is suitable for large urban power grid with diverse load characteristics and different reliability requirements of functional areas. Based on an analysis of the new demand for the development of the urban power grid and the shortages of the existing defense measures, a coordinated decision-making model is given considering the cost of measures and the risk of accidents. And then, the enumeration combination and cluster iterative computing are used to search the optimal preventive control strategies for partition load transfer and feeding user load shedding, which will lay the foundation for large urban power grid to realize meticulous, differential and integrated prevention of accidents. The correctness and feasibility of the proposed method are verified by simulation analysis of actual power grid operation data.

Key words: preventive control, large urban power grid, partition load transfer, load shedding scheme
