A Data-Driven Optimal Power Flow Model under Partial Observability
Zhongguo dianli, 2023 The linearized power flow (PF) model is mainly used to make the optimal power flow (OPF) problem convex. However, existing data-driven linear PF models are mostly based on complete system measurement data.

A General Formulation for Evaluating the Performance of Linear Power Flow Models [PDF]
, 2022 Linear power flow (LPF) models are essential in power system analysis. Various LPF models are proposed, but some crucial questions are still remained: what is the performance bound (e.g., the error bound) of LPF models, how to know whether an LPF model is applicable for a branch or not, and what is the best LPF model.

Fast Heuristic AC Power Flow Analysis with Data-Driven Enhanced Linearized Model
Energies, 2020 Though the full AC power flow model can accurately represent the physical power system, the use of this model is limited in practice due to the computational complexity associated with its non-linear and non-convexity characteristics.

Topology-Aware Piecewise Linearization of the AC Power Flow Through Generative Modeling
2023 North American Power Symposium (NAPS), 2023 Effective power flow modeling critically affects the ability to efficiently solve large-scale grid optimization problems, especially those with topology-related decision variables. In this work, we put forth a generative modeling approach to obtain a piecewise linear (PWL) approximation of AC power flow by training a simple neural network model from ...
