摘　　要：给出一种基于直流潮流灵敏度的断面潮流定向控制新方法。首先利用直流潮流获得断面支路对应的发电机输出功率转移分布因子(GSDF)矩阵;进而根据断面潮流定向控制需要,利用断面的GSDF矩阵,通过非线性优化确定断面潮流调控方案。该方法不仅可实现对断面总潮流的准确控制,并可兼顾各支路潮流不同变动目标的定向要求。New England 39节点、IEEE118节点等系统验证结果表明,该方法可对断面潮流进行较精确的定向控制,工程应用前景良好。A new interface power control method based on DC power flow and sensitivity analysis is presented.In the proposed algorithm,firstly,DC power flow is used to calculate the matrix of generation shift distribution factor（GSDF）.Further,according to the needs of power control,using the information of GSDF matrix,the control scheme can be obtained through nonlinear optimization.By this algorithm,the total power flow of the interface can be controlled exactly and,furthermore the constraints of power exchange between different islands can be satisfied.The proposed algorithm is validated by some systems,such as New England 39-bus system,IEEE 118-bus system,et al.It is revealed that the method can exactly control the interface power in large-scale systems and has a good application prospect.
