Framework to Analyze Interactions between Transmission and Distribution (T&D) Systems with High Distributed Energy Resource (DER) Penetrations (T-60)

Summary This project aims at developing an integrated T&D system analysis framework to study and mitigate the impacts of high penetrations of DERs. A coupled T&D analysis framework is developed through co-simulation approach. The framework utilizes legacy software to separately solve the decoupled models. The T&D interactions are captured by exchanging network solutions at the point of common coupling (PCC). The co-simulation approach adds modularity to the analysis and helps in achieving speed and scalability. The framework is utilized to understand and mitigate the impacts of high DER penetrations. Power quality issues which are otherwise difficult to model are studied, and mitigation schemes are proposed. Finally, the utility of DERs as an active participant in system operations is explored.
