Continuous Switch Model and Heuristics for Mixed-Integer Problems in Power Systems
Aayushya Agarwal, Amritanshu Pandey, Larry Pillegi
Many power systems operation and planning computations (e.g., transmission and generation switching and placement) solve a mixed-integer nonlinear problem (MINLP) with binary varia…
Equivalent Circuit Programming for Power Flow Analysis and Optimization
Marko Jereminov, Larry Pileggi
The utility of domain-specific knowledge for modeling, simulation, and optimization has been demonstrated for various research problem domains, including power systems. The concept…
SUGAR-R: Robust Online Restoration Platform for SCADA-Absent Grid
Amritanshu Pandey, Aayushya Agrawal, Marko Jereminov +1
Secure and fast grid restoration from a collapsed state is increasingly critical as blackouts are becoming more prevalent around the globe. Generally, the restoration of grid durin…
Implicitly Modeling Frequency Control within Power Flow
Aayushya Agarwal, Amritanshu Pandey, Marko Jereminov +1
In this paper, we extend a circuit-based, current-voltage power flow formulation to include frequency deviations and implicitly model generator primary and secondary control action…
Robust Probabilistic Analysis of Transmission Power Systems based on Equivalent Circuit Formulation
Martin R. Wagner, Amritanshu Pandey, Marko Jereminov +1
Recent advances in steady-state analysis of power systems have introduced the equivalent split-circuit approach and corresponding continuation methods that can reliably find the co…
Aggregated Load and Generation Equivalent Circuit Models with Semi-Empirical Data Fitting
Amritanshu Pandey, Marko Jereminov, Xin Li +2
In this paper we propose a semi-empirical modeling framework for aggregated electrical load and generation using an equivalent circuit formulation. The proposed models are based on…
Improving Power Flow Robustness via Circuit Simulation Methods
Amritanshu Pandey, Marko Jereminov, Gabriela Hug +1
Recent advances in power system simulation have included the use of complex rectangular current and voltage (I-V) variables for solving the power flow and three-phase power flow pr…
Robust Convergence of Power Flow using Tx Stepping Method with Equivalent Circuit Formulation
Amritanshu Pandey, Marko Jereminov, Martin R. Wagner +2
Robust solving of critical large power flow cases (with 50k or greater buses) forms the backbone of planning and operation of any large connected power grid. At present, reliable c…
