A Voronoi Diagram‐Based Approach for AC Optimal Power Flow

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper presents a new approach for AC optimal power flow. The proposed approach begins by constructing a Voronoi diagram using a set of initial sample points that represent candidate solutions distributed across the search space. It then iteratively adds new sample points, including: (i) a tentative optimal point obtained via the continuous ...

Distributionally Robust Optimization Economic Dispatch for Power Systems With High Wind Penetration Under Extreme Cold Waves

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
First, the fuzzy set defined by the Wasserstein metric is constructed by using historical wind data. Second, the XGB‐transformer model is used to predict the likelihood distribution of wind power output. Next, a distributed robust scheduling model is built for the power system to ensure the operation robustness and minimise the total operation cost ...

AC OPF in Radial Distribution Networks - Parts I,II [PDF]

, 2015
The optimal power-flow problem (OPF) has played a key role in the planning and operation of power systems. Due to the non-linear nature of the AC power-flow equations, the OPF problem is known to be non-convex, therefore hard to solve.
