Optimal transmission switching analysis and marginal switching results

2011 IEEE Power and Energy Society General Meeting, 2011
Strategically removing transmission lines from service has been shown to produce significant system cost savings. This optimization of the transmission network topology is known as transmission switching. The mixed-integer linear programming problem presented by Optimal Transmission Switching is too complex to solve on large systems in real time. Here,

Transmission congestion management through optimal transmission switching

2011 IEEE Power and Energy Society General Meeting, 2011
In both restructured and vertically integrated power systems, it is desirable to transmit power to remote locations without causing any congestion and consequently avoiding inefficiency in generation dispatch. In this paper, in order to relieve network congestion, transmission switching is employed as a powerful tool to change network topology which ...

Correcting Optimal Transmission Switching for AC Power Flows

2014 47th Hawaii International Conference on System Sciences, 2014
Optimal Transmission Switching (OTS) has demonstrated significant savings potential on test systems when formulated in a linearized DC power flow framework. OTS solutions generated from DC models, however, are not guaranteed to produce a feasible AC dispatch.

A practical implementation of optimal transmission switching

2011 4th International Conference on Electric Utility Deregulation and Restructuring and Power Technologies (DRPT), 2011
Transmission elements are traditionally treated as non-dispatchable asset in the network. Co-optimizing transmission topology and generation dispatch could be a viable way to further maximize the market surplus and improve economic efficiency. This paper will discuss the mathematical formulation of optimal transmission switching.

Optimality of Monotone Policies for Transmission Control with Switching Costs

2007 46th IEEE Conference on Decision and Control, 2007
This paper considers a time slotted transmission system over a finite state Markovian channel where in each time slot a transmission mode is dynamically selected from a finite set. There is a switching cost for changing the transmission mode and there is a channel dependent delay cost associated with each transmission mode.

Approximate optimal transmission switching

Electric Power Systems Research, 2018
Abstract Optimal transmission switching (OTS) has been proposed as a new control paradigm to improve the economics of electric power systems. The problem is formulated as mixed integer linear programming in which binary decision variables are used to represent the on and off state of transmission lines.

Flexible Transmission in the Smart Grid: Optimal Transmission Switching

2011
There is currently a national push to create a smarter, more flexible electrical grid. Traditionally, network branches (transmission lines and transformers) in the electrical grid have been modeled as fixed assets in the short run, except during times of forced outages or maintenance. This traditional view does not permit reconfiguration of the network

Network modeling using optimal transmission switching

2017 IEEE Calcutta Conference (CALCON), 2017
The aim of this paper is to identify an optimized network in an existing system which has minimized active power loss and generation cost obtainable through change in topology by reorganizing the switch status and remodeling the production schedules. The transmission system is made to participate with and function in coordination with the generating ...

Determination of Optimal Topology for Transmission Networks with Distributed Generation using Optimal Transmission Switching (OTS)

2021 IEEE Region 10 Symposium (TENSYMP), 2021
Optimal Transmission Switching (OTS) is the strategic removal of transmission lines to be out of service to optimize power system operating parameters. This technique has been established by several research to produce significant cost savings while maintaining the voltage security, stability, flexibility, and reliability for a transmission network ...

Probabilistic Security Analysis of Optimal Transmission Switching

IEEE Transactions on Power Systems, 2016
Optimal transmission switching (OTS) optimizes simultaneously the generation dispatch and the topology of a power system. It has been shown that taking some transmission lines out of service can significantly reduce the operating cost of the system while respecting the traditional deterministic $N-1$ security criterion of operational reliability ...
