摘要

随着直流输电比例的不断增加，以交流输电为主的电网，其潮流计算必将考虑直流输电影响以及交直流关联的机制等基础问题。为此，文中根据直流输电单元的物理方程，以及其不同控制方式间的相通性，在潮流计算中增加直流输电单元的直流电流作为状态变量，以实现直流输电单元与交流（整流、逆变）系统的有机关联。由此建立交直流混合潮流模型，并基于牛顿法进行求解。该研究在力求保留交直流潮流关联机制前提下，使雅可比矩阵维数最小

实现交直流潮流关联机制的直接可观

为评价或调控交直流混合电网提供基础工具。以22节点系统为例，验证了所提算法的有效性。

Abstract

With the development of HVDC transmission systems

the power flow calculation dominated by AC power grid is bound to face fundamental problems of handling the HVDC transmission unit and the link mechanism. Such being the case

according to the basic equations of DC transmission units and the connectivity of various control modes

the current is taken as a state variable in the power flow calculation to make the DC transmission unit organically combine with AC power system. Based on the above

the DC/AC hybrid power flow equations are established and Newton iteration algorithm is applied to solving the model. On the premise of the link mechanism of AC/DC power system

the study aims to minimize the dimension of the Jacobian matrix and realize direct observation of the operation state of the DC transmission unit

providing a basic tool to evaluate or control the AC/DC system. The algorithm is proved effective with a 22-bus system. This work is supported by National Natural Science Foundation of China (No. 51177091).
