Summary
Transient stability in distribution systems has gained special interest because of the continuous increase of distributed generation connected to the grid. Besides the dynamic behavior of the generation system, the distribution networks present extensive branches and unbalanced loads with a specific set of equipment, what increases 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, which is divided in 3 major steps: (1) the representation of the network model through a simplified model, (2) the selection of disturbances types and buses for application, and (3) and the adjustment of stability control systems. The methodology is suitable for unbalanced networks and a demonstration of a single‐pole switching is presented. Some case studies were simulated and analyzed for a real network model.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
