Abstract: (1469 Views)
The ever-increasing consumption of electricity has necessitated the continuous expansion of power networks. As these networks grow and the order of the dynamic system models increases, the complexity and duration of numerous studies, such as stability analyses, become excessively high. Therefore, the use of model order reduction techniques becomes crucial. To address this, power engineers typically divide the network under study into two regions: the study area and the external area. A reduced model is then used for the external area to both expedite various studies in the study area and account for the external area's influence in these analyses. This review paper meticulously examines coherency-based methods as the most commonly used techniques for reducing the order of power system models, detailing the advantages and disadvantages of each method. This provides guidance for selecting the most appropriate method for the intended application.
Keywords: Dynamic model order reduction, coherency, generator aggregation, power network dimensionality reduction
