A Data-Driven Optimal Power Flow Model under Partial Observability

open access: yesZhongguo 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.
