针对传统算法不适用于输配电网一体化潮流计算这一情况，提出输配协同潮流算法。该算法基于输配电网之间的电气连接关系及其各自网络结构特点，对整个网络进行区域划分，建立输配电网边界映射区，处理其失配功率，给出收敛判据。根据配电网部分不同地区的网络结构特征，采用适合的算法对配电网进行分区计算。针对一体化潮流计算时电网中负荷功率被人工置数的情况，给出相应处理方法。以广州输配电网为例进行了计算，验证了协同潮流算法的准确性和多适配性。

In allusion to the situation that the traditional algorithms do not apply to power flow calculation of integrated transmission and distribution network, this paper constructs a cooperative power flow calculation algorithm. Based on the electrical connection relationship and structural characteristics of these two networks, the algorithm makes region division, builds boundary mapping area, processes mismatching power and discusses convergence judgements. According to the structure characteristics in different regions of distribution, appropriate algorithm is used for each division. A treatment method is given when the load power is manually set. The transmission and distribution network of Guangzhou is taken as a test case and the result shows the accuracy and multi-suitability of this algorithm.
