摘　　要：结合电网中的不同电力公司所辖电网具有相互独立且互联的特点,提出一种适于大区域互联电网的分布式输电能力协同计算方法。该方法通过分解-协调模型实现互联电网的解耦,采用增广拉格朗日法和辅助问题原理实现输电能力按地理分区,形成一个迭代形式的分布式输电能力计算框架,迭代中通过交换边界节点信息将互联外网信息反映到各分区的计算中,各地的子网络计算相对独立。新英格兰10机39节点测试系统证明该文所提方法的有效性。A new approach to compute distributed transfer capability is presented, which is suitable for distributed implementation, especially in deregulated environment. Based on decomposition-coordination model of an electric power system, the general augmented Lagrange method and auxiliary problem principle are adopted to form iterative distributed transfer capability computation framework, in which the influence on the internal system exposed by external system is considered through exchanging the information of boundary nodes. Test on New England 10-machine 39- bus system shows the validity of proposed method.
