Optimal Transmission Switching With Contingency Analysis

IEEE Transactions on Power Systems, 2009
In this paper, we analyze the N-1 reliable DC optimal dispatch with transmission switching. The model is a mixed integer program (MIP) with binary variables representing the state of the transmission element (line or transformer) and the model can be used for planning and/or operations.

Optimal Transmission Switching Considering Probabilistic Reliability

IEEE Transactions on Power Systems, 2014
A multi-objective (MO) optimization approach is proposed in this letter to develop optimal transmission switching strategies with minimal generating cost and maximal probabilistic reliability. The problem is solved via an evolutionary algorithm together with Monte Carlo simulation to capture the probabilistic nature of system component failures.

Optimal Transmission Switching With Short-Circuit Current Limitation Constraints

IEEE Transactions on Power Systems, 2016
With the expansion and enhancement of the power transmission network, short-circuit current (SCC) has become a major concern in grid operations. While transmission switching is one effective solution to reduce the SCC without investing in additional equipment, switching lines could threaten system N-1 security.

A genetic algorithm for AC optimal transmission switching

Proceedings of the Genetic and Evolutionary Computation Conference, 2021
Optimal transmission switching (OTS) is a new practice in power systems and can improve the economics of electric power systems integrated with renewable resources such as wind. In OTS modeling binary decision variables are added to the optimal power flow (OPF) problem to represent on and off switching status of lines.

Optimal Transmission Switching with Injection Uncertainties

2020 IEEE Power & Energy Society General Meeting (PESGM), 2020
In this paper, a robust optimization model is solved for the optimal transmission switching problem of the power networks to cater to the short-term uncertainties in the power injections of demands and renewable energy sources. The novelty of the proposed model is that the base-point generation of the conventional generators and the switching statuses ...

Robust optimal power flow with transmission switching

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
To deal with the increasing penetration of uncertainties caused by renewable generations and uncertain loads, this paper proposes a novel robust optimization model for the optimal power flow (OPF) problem of power systems. In the model proposed, the generation and the network topology are co-optimized, and then the proposed robust optimal power flow ...

Primal and dual bounds for Optimal Transmission Switching

2014 Power Systems Computation Conference, 2014
It has been suggested that Optimal Transmission Switching (OTS) may reduce generator dispatch costs by as much as 10%, saving millions of dollars annually. However, this conclusion has been deduced primarily from studies using the DC power flow approximation on two power networks derived from the IEEE 118-bus and RTS-96 cases.
