RESUMO:

Traditionally, the dynamic response of distribution networks is represented in stability simulations by an equivalent representing the load behavior. In networks with distributed generation (DG), it is common for generation to be represented as a negative load. However, with the significant increase of DG units, there is a need to represent these distribution systems considering the generation connected to them. This article presents a methodology for obtaining a dynamic equivalent of microgrids, which has models for representing static and dynamic loads and DG connected via converters and synchronous generators. The method is based on the gray-box approach, in which it is assumed an equivalent model composed of known physical components. Additionally, an advantage of this approach is the fact that the parameters of the equivalent model are calculated based on measurements taken in the point of common coupling (PCC) and, as a result, it is not necessary to know the parameters of the different components connected to the distribution system. The methodology is validated using computer simulations with a medium voltage test distribution network. The results confirm that the equivalent can be used to represent distribution systems with DG.
