A Cycle-Based Formulation and Valid Inequalities for DC Power Transmission Problems with Switching

open access: yes, 2015
It is well-known that optimizing network topology by switching on and off transmission lines improves the efficiency of power delivery in electrical networks. In fact, the USA Energy Policy Act of 2005 (Section 1223) states that the U.S.

Wireless Information Transfer with Opportunistic Energy Harvesting [PDF]

open access: yes, 2012
Energy harvesting is a promising solution to prolong the operation of energy-constrained wireless networks. In particular, scavenging energy from ambient radio signals, namely wireless energy harvesting (WEH), has recently drawn significant attention. In

T-WAS and T-XAS algorithms for fiber-loop optical buffers

open access: yes, 2020
In optical packet/burst switched networks fiber loops provide a viable and compact means of contention resolution. For fixed size packets it is known that a basic void-avoiding schedule (VAS) can vastly outperform a more classical pre-reservation ...

Tight big-Ms for Optimal Transmission Switching

open access: yesElectric Power Systems Research
This paper addresses the Optimal Transmission Switching (OTS) problem in electricity networks, which aims to find an optimal power grid topology that minimizes system operation costs while satisfying physical and operational constraints. Existing methods typically convert the OTS problem into a Mixed-Integer Linear Program (MILP) using big-M constants.

Formulating Connectedness in Security-Constrained Optimal Transmission Switching Problems

open access: yesIEEE Transactions on Power Systems, 2022
<p>This paper focuses on the issue of network connectedness</p> <p>(NC) in security-constrained optimal transmission switching problems, which is complicated by branch contingencies and corrective line switching. Two criteria are firstly proposed with the principle of preserving NC as much as possible within reasonable limits.
