A General Formulation for Evaluating the Performance of Linear Power Flow Models

Linear power flow (LPF) models are essential in system analysis. Various LPF proposed, but some crucial questions still remained: what is the performance bound (e.g., error bound) of models, how to know a branch applicable for or not, and best model. In this paper, these answered general formulation (GF) evaluating proposed. The GF actually figure out two core difficulties, one define definition range second analytically obtain model evaluate given Besides, key factors that affect also analyzed through proposed framework. case studies compare with DC model, physical-model-driven data-driven results show effectiveness as well superiority method.
