本文提出了一种新的利用联络线功率突变的黑盒等效方法，特别适用于不知道任何外部网络信息的二端口或三端口互联电网。该方法基于简化的外部网络Ward等效模型，旨在解决现有基于黑盒的静态等效方法参数估计不稳定、精度低或实现困难等问题。相应的，本文提出的方法能够解决上述问题的主要特点是：1)易于实现，只涉及内部网格设计的大扰动前后两个相邻时间瞬间的边界节点的关联测量；2)对测量误差具有鲁棒性，保证了更准确的等效建模；3)它既可以应用于双端口等效网络，也可以应用于三端口等效网络。新英格兰39节点测试用例和中国广东实际电网用例的仿真结果验证了所提方法的有效性和性能。
A new black-box equivalent method by using tie-line power mutation is proposed in this paper, which is especially suitable for a two-port or three-port interconnected grid that does not know any information of the external network. The proposed method, based on the simplified Ward equivalent model of the external network, aims to addresses the following issues: unstable parameter estimation of the existing black-box-based static equivalence method and low accuracy or difficult implementation. Correspondingly, the main features of the proposed method, which makes it as a solution for these existing issues above, are summarized as follows: 1) it is easy to implement, as it only involves the associated measurements of boundary nodes in two adjacent time instants that are before and after a designed large disturbance of the internal grid; 2) it is robust to measurement errors, thus guaranteeing more accurate equivalent modeling; and 3) it can be applied to both the two-port and three-port equivalent networks. The simulation results of the New England 39-node test case and the actual electric grid case in Guangdong of China validate the effectiveness and performance of the proposed method.
