The power of convex relaxation
WebbIn many important problems, only partial information about an object of interest is available. In signal processing, we may have far fewer measurements about an image we wish to reconstruct than the number of pixels in the image—as in common biomedical applications. In data analysis, we may be interested in knowing users' preferences for a … Webb13 dec. 2024 · The problem of optimal siting and sizing of distribution static compensators (STATCOMs) is addressed in this research from the point of view of exact mathematical optimization. The exact mixed-integer nonlinear programming model (MINLP) is decoupled into two convex optimization sub-problems, named the location problem and the sizing …

WebbA variety of formulations, from non-linear to convexified to linearized, are developed and implemented in an open-source tool. A convex relaxation formulation of a parameterized ac-dc converter model is developed. The hierarchy of common ac optimal power flow formulations is mapped to formulations for converter stations and dc grids.
