本文提出了一种新的非线性模型降阶公式，用于获得大型电力系统的降阶模型。新的公式是基于识别慢相干区和外部网络。对于每个慢相干区域，网络和简化模型的动态分别聚合。相干区域的网络聚合仅基于其参数来执行，并且独立于其他相干区域。动态模型聚合是一个非线性输入输出模型的近似。该公式将允许开发新的方法来获得总的发电机和控制装置模型。
This paper presents a new nonlinear model reduction formulation for obtaining reduced models of large power systems. The new formulation is based on identifying the slow-coherent areas and the external network. For each slow-coherent area, the network and the dynamics of the reduced model are aggregated separately. The network aggregation of a coherent area is performed based on only its parameters and is independent of the other coherent areas. The dynamic model aggregation is formulated as the approximation of a nonlinear input-output model. The formulation would allow the development of new approaches to obtain aggregate generator and control device models.
