Modeling and Rapid Prototyping of Integrated Transmission-Distribution OPF Formulations with PowerModelsITD.jl

1 code implementation28 Oct 2022 Juan Ospina, David M. Fobes, Russell Bent, Andreas Wächter

However, coupling models and formulations between transmission and distribution is non-trivial, in particular due to the common practice of modeling transmission systems as single-phase, and distribution systems as multi-conductor phase-unbalanced.

CPES-QSM: A Quantitative Method Towards the Secure Operation of Cyber-Physical Energy Systems

no code implementations7 Jun 2022 Juan Ospina, Venkatesh Venkataramanan, Charalambos Konstantinou

Power systems are evolving into cyber-physical energy systems (CPES) due to the integration of modern communication and Internet-of-Things (IoT) devices.

Faster than Real-Time Simulation: Methods, Tools, and Applications

no code implementations9 Apr 2021 Xiaorui Liu, Juan Ospina, Ioannis Zografopoulos, Alonzo Russell, Charalambos Konstantinou

Namely, the provided acceleration can be used for improving system scheduling, assessing system vulnerabilities, and predicting system disruptions in real-time systems.

Cyber-Physical Energy Systems Security: Threat Modeling, Risk Assessment, Resources, Metrics, and Case Studies

no code implementations25 Jan 2021 Ioannis Zografopoulos, Juan Ospina, Xiaorui Liu, Charalambos Konstantinou

Leveraging the threat model formulation, we present a CPS framework designed to delineate the hardware, software, and modeling resources required to simulate the CPS and construct high-fidelity models which can be used to evaluate the system's performance under adverse scenarios.

Modeling Communication Networks in a Real-Time Simulation Environment for Evaluating Controls of Shipboard Power Systems

no code implementations15 Aug 2020 Colin Ogilvie, Juan Ospina, Charalambos Konstantinou, Tuyen Vu, Mark Stanovich, Karl Schoder, Mischa Steurer

Interest by the U. S. Navy in the development and deployment of advanced controls in future shipboard platforms has motivated the development of the Controls Evaluation Framework (CEF) for use in investigating dynamics present in complex automated systems.
