A Survey on Mixed-Integer Programming Techniques in Bilevel Optimization

EURO Journal on Computational Optimization, 2021
Bilevel optimization is a field of mathematical programming in which some variables are constrained to be the solution of another optimization problem. As a consequence, bilevel optimization is able to model hierarchical decision processes.

Restoration model for unbalanced distribution networks considering renewable sources uncertainties

Energy Reports, 2023
Extreme events cause blackouts, resulting in the distribution network being unable to obtain power from the upstream transmission system. In this situation, local distributed resources can be fully utilized to improve system resilience.

A generic multi‐period optimal power flow framework for combating operational constraints via residential flexibility resources

IET Generation, Transmission & Distribution, 2021
In low voltage networks, the majority of distributed energy resources are customer owned. As such, it is harder for the distribution system operator to control its system and maintain acceptable operating conditions.

A Comparison of the Embedding Method to Multi-Parametric Programming, Mixed-Integer Programming, Gradient-Descent, and Hybrid Minimum Principle Based Methods

, 2013
In recent years, the embedding approach for solving switched optimal control problems has been developed in a series of papers. However, the embedding approach, which advantageously converts the hybrid optimal control problem to a classical nonlinear ...

Elastomeric Micro‐Balloons for Remote Control of Cerebral Blood Flow and Real‐Time In vivo Imaging of Rodent Brain Response to Hypoperfusion

Advanced Materials, EarlyView.
This study reports the fabrication of MRI‐compatible elastomeric micro‐balloons via a multi‐step bubble casting process, where the monolithic elastomeric wall is selectively stiffened for reversible and controlled inflation and elasticity, depending on the target vessels for graded occlusion of cerebral arteries.
