Optimal Transmission Switching [PDF]
IEEE Transactions on Power Systems, 2008 In this paper, we formulate the problem of finding an optimal generation dispatch and transmission topology to meet a specific inflexible load as a mixed integer program. Our model is a mixed-integer linear program because it employs binary variables to represent the state of the equipment and linear relationships to describe the physical system.

The Role of Optimal Transmission Switching in Enhancing Grid Flexibility: A Review
IEEE Access, 2023 The integration of variable renewable energy sources (RES) into power grids has resulted in a more complex operating environment for power system operators (SO), necessitating the need for increased grid flexibility. This is crucial for utilities, as the

Node-based valid inequalities for the optimal transmission switching problem [PDF]
Discrete Optimization, 2022 The benefits of transmission line switching are well-known in terms of reducing operational cost and improving system reliability of power systems. However, finding the optimal power network configuration is a challenging task due to the combinatorial nature of the underlying optimization problem.

Stochastic optimization for AC optimal transmission switching with generalized Benders decomposition
International Journal of Electrical Power and Energy Systems, 2021 Abstract Optimal transmission switching is proposed in recent years to optimize the power system operational cost in deterministic studies. With the rapid growth of renewable generations, the grid uncertainties have greatly increased, which cannot be ignored in the decision-making of optimal transmission switching problems.

Formulating Connectedness in Security-Constrained Optimal Transmission Switching Problems
IEEE Transactions on Power Systems, 2022 This paper focuses on the issue of network connectedness (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.

Ensuring Network Connectedness in Optimal Transmission Switching Problems [PDF]
IEEE Transactions on Circuits and Systems II: Express Briefs, 2021 Network connectedness is indispensable for the normal operation of transmission networks. However, there still remains a lack of efficient constraints that can be directly added to the problem formulation of optimal transmission switching (OTS) to ensure network connectedness strictly. To fill this gap, this paper proposes a set of linear connectedness
