Optimization-Based Islanding of Power Networks Using Piecewise Linear AC Power Flow [PDF]

open access: yesIEEE Transactions on Power Systems, 2014
In this paper, a flexible optimization-based framework for intentional islanding is presented. The decision is made of which transmission lines to switch in order to split the network while minimizing disruption, the amount of load shed, or grouping coherent generators.

A Linear Power Flow Formulation for Three-Phase Distribution Systems [PDF]

open access: yesIEEE Transactions on Power Systems, 2016
Power flow analysis is one of the tools that is required in most of the distribution system studies. An important characteristic of distribution systems is the load unbalance in the phases and a three-phase power flow analysis is needed. In this paper, a three-phase linear power flow (3LPF) formulation is derived based on the fact that in a typical ...

Linear/Quadratic Programming-Based Optimal Power Flow Using Linear Power Flow and Absolute Loss Approximations [PDF]

open access: yesInternational Journal of Electrical Power and Energy Systems, 2019
This paper presents novel methods to approximate the nonlinear AC optimal power flow (OPF) into tractable linear/quadratic programming (LP/QP) based OPF problems that can be used for power system planning and operation. We derive a linear power flow approximation and consider a convex reformulation of the power losses in the form of absolute value ...
