PPT-New Formulations of the Optimal Power Flow Problem

Daniel Kirschen Close Professor of Electrical Engineering University of Washington 2011 D Kirschen and the University of Washington 1 Outline A bit of background The power flow problem. Optimal Power Flow uses stateoftheart techniques including an interior point method with barrier functions and infeasibility handling to achieve ultimate accuracy and flexibility in solving systems of any size Optimal Optimal Secure Objective Contro T his problem named optimal power 64258ow OPF is nonconvex due to the nonlinearities imposed by the laws of physics and has been studied since 1962 We have recently shown that a convex relaxation based on semide64257nite programming SDP is able t 64 Daniel Kirschen. © 2011 D.
