Enhancing Power System Stability: Integrating High-Fidelity Plant Controller Models for Distributed Energy Resources

The paper presents a detailed study on the utilization of high-fidelity device models (also referred to as digital twins) in power system simulations. This technology is pivotal in understanding the impact of integrating distributed energy resources (DERs) into the bulk power grid, a pressing challenge in modern power systems. The paper particularly emphasizes the role and benefits of these advanced models in assessing the installation of new power management connections, which are crucial for maintaining grid stability and performance. The testing approach presented in the paper was used to demonstrate the compliance of an existing power management project with the standards applicable to connection rules for medium- and high-voltage installations (VDE-AR-N 4110, VDE-AR-N-4120).
