Transient stability in distribution systems has gained special interest due to the continuous increase of distributed generation connected to the grid. Besides the dynamic behavior of the generation system, distribution networks have extensive branches and unbalanced loads, with a specific set of equipment, increasing the complexity of the numerical analysis of transient stability. In this context, this work proposes a new methodology for transient analysis in distribution networks with distributed generation, divided in three major steps: the representation of the network model through a simplified model; the selection of disturbances types and buses for application, and the adjustment of stability control systems. The methodology is suitable for unbalanced networks and a demonstration of a single-pole switching is presented. Case studies are simulated and analyzed for a real network model.
