提出了一种基于灰箱法的有源分布式网络动态等值模型。ADN的等效模型包括并联的变流器连接的发电机和复合负荷模型。选择灰盒方法进行模型开发，因为它将有关ADN结构的先验知识纳入模型中，使模型比黑盒或白盒模型更具物理相关性和直观性，并可能提高模型的准确性。建立了七阶非线性状态空间形式的动力学等效模型。它最初是从代数和微分方程松散地发展起来的，这些方程描述了ADN的假定典型组件。各种静态负荷模型，动态负荷组成，故障位置和各种分布式发电类型和情况被认为是为了建立通用范围的模型参数的ADN。该模型的目的是在大型电力系统的稳定性研究中使用。
This paper presents the development of the dynamic equivalent model of an active distributed network (ADN) based on the grey-box approach. The equivalent model of an ADN comprises a converter-connected generator and a composite load model in parallel. The grey-box approach was chosen for model development as it incorporates prior knowledge about the ADN structure into the model, makes the model more physically relevant and intuitive than black-box or white-box models, and potentially improves the accuracy of the model. The dynamic equivalent model is presented in the seventh-order nonlinear state space format. It was initially loosely developed from the algebraic and differential equations describing assumed typical components of an ADN. Various static load models, dynamic load compositions, fault locations and a diverse range of distributed generation types and scenarios are considered in order to establish the generic range of model parameters for an ADN. The model is intended for the use in large power system stability studies.
