New Formulation and Strong MISOCP Relaxations for AC Optimal Transmission Switching Problem [PDF]
IEEE Transactions on Power Systems, 2017 As the modern transmission control and relay technologies evolve, transmission line switching has become an important option in power system operators' toolkits to reduce operational cost and improve system reliability. Most recent research has relied on the DC approximation of the power flow model in the optimal transmission switching problem. However,

MicroGrid Resilience-Oriented Scheduling: A Robust MISOCP Model [PDF]
IEEE Transactions on Smart Grid, 2021 This article introduces a Robust Mixed-Integer Second Order Cone Programming (R-MISOCP) model for the resilience-oriented optimal scheduling of microgrids (MGs). This is developed for MGs that are islanded due to a scheduled interruption from the main grid, where minimizing both operational costs and load shedding is critical.

An MISOCP-Based Solution Approach to the Reactive Optimal Power Flow Problem [PDF]
IEEE Transactions on Power Systems, 2021 In this letter, we present an alternative mixed-integer non-liner programming formulation of the reactive optimal power flow (ROPF) problem. We utilize a mixed-integer second-order cone programming (MISOCP) based approach to find global optimal solutions of the proposed ROPF problem formulation.
