摘　　要：电力孤岛运行是智能电网中的一种特殊运行方式。对于输电网而言,在系统危急情况下按最优孤岛方式及时地将互联电网划分成多个能够稳定运行的孤岛系统,既可以避免局部事故扩散引发大面积停电甚至系统崩溃所带来的巨大损失,又使得切机切负荷量最小;对于含分布式发电的配电网而言,优化的孤岛运行方式可以充分发挥分布式能源的潜力,提高配电系统的供电可靠性。文中在总结智能电网最优孤岛划分影响因素的基础上,对该领域国内外相关研究成果进行了全面分析和分类,指出了各类方法的优缺点及关键问题;进而阐述了电力孤岛的最优形成问题的发展趋势及亟待解决的问题。Islanding operation is a special operation mode in the smart grid. For a power transmission system, if a connected system is split into several stable islanding sub-systems in time in the optimal islanding operation mode in case of extreme emergency, not only will enormous losses due to large area blackout or even system collapse caused by the spread of the local fault be avoided, but the amount of load shedding and generator tripping might be minimized as well. For a distributed system with distributed generator （DG）, optimum islanding operation can bring the potential of DG into full play, while improving the reliability of power supply. The influencing factors of the optimal island partitioning in the smart grid are summed up and all the relevant methods and strategies available at home and abroad are thoroughly analyzed and classified. And the advantages and disadvantages along with key issues of each method are also discussed. Finally, the development tendency and the problems demanding prompt solution are treated.
