title = "T\&D LIBRA: Simulation Framework for Transmission and Distribution Load and IBR Assessment",
abstract = "This paper introduces T\&D LIBRA, a HELICS-based dynamic co-simulation framework designed for transmission and distribution (T\&D) load and inverter-based resource assessment. This framework is designed to model interactions between single-phase induction motors (i.e., Motor-D), distributed energy resources (DERs) and the transmission network, emphasizing system stability during fault conditions. The primary objective of this research is to study the fault-induced delayed voltage recovery (FIDVR) behavior of the T\&D networks using the co-simulation framework and to compare the results with conventional PSS/E only simulations. Simulations are validated using T\&D co-simulations with a single distribution node and the IEEE 123-bus distribution test case. The co-simulation results demonstrate the value of using T\&D co-simulations to capture motor stalling, DER tripping and other sources of voltage diversity on distribution networks.",
