A Feasibility Pump for mixed integer nonlinear programs [PDF]
Mathematical Programming, 2008 We present an algorithm for finding a feasible solution to a convex mixed integer nonlinear program. This algorithm, called Feasibility Pump, alternates between solving nonlinear programs and mixed integer linear programs. We also discuss how the algorithm can be iterated so as to improve the first solution it finds, as well as its integration within ...

Polyhedral approximation strategies for nonconvex mixed-integer nonlinear programming in SHOT
Journal of Global Optimization, 2021 Different versions of polyhedral outer approximation are used by many algorithms for mixed-integer nonlinear programming (MINLP). While it has been demonstrated that such methods work well for convex MINLP, extending them to solve nonconvex problems has ...

Optimal operation method for load restoration of distribution networks under disturbance scenario
Energy Reports, 2022 Extreme events can cause damages to transmission system equipment, resulting in a major power outage. In disturbance scenario, local distributed energy resources (DERs) and switches can be fully utilized to restore power loads, which is critical for ...

Optimal Network Topology for Node-Breaker Representations With AC Power Flow Constraints
IEEE Access, 2020 It has been demonstrated that network topology optimization (NTO) may change the topology of power system networks, and consequently, provide additional flexibility to reduce network congestion and violations.

Branch-and-price for a class of nonconvex mixed-integer nonlinear programs [PDF]
Journal of Global Optimization, 2021 This work attempts to combine the strengths of two major technologies that have matured over the last three decades: global mixed-integer nonlinear optimization and branch-and-price. We consider a class of generally nonconvex mixed-integer nonlinear programs (MINLPs) with linear complicating constraints and integer linking variables.

A mixed-integer linear programming approach for robust state estimation
Journal of Modern Power Systems and Clean Energy, 2014 In this paper, a mixed integer linear programming (MILP) formulation for robust state estimation (RSE) is proposed. By using the exactly linearized measurement equations instead of the original nonlinear ones, the existing mixed integer nonlinear ...
