A multiple choice relaxation model to solve the AC optimal power flow

International Journal of Electrical Power & Energy Systems
Mathematically speaking, AC optimal power flow (OPF), seeking an optimal state of a power system, is an NP-hard nonconvex optimization problem. In the past two decades, many researchers have attempted to accurately solve the AC OPF problem, that is ...

Toward economic NMPC for multistage AC optimal power flow

, 2019
Recently, there has been a considerable progress on the analysis of stability and performance properties of so-called economic nonlinear model predictive control (nmpc) schemes, ie, schemes employing stage costs that are not directly related to distance ...
