Incremental cutting-plane method and its application
Nagisa Sugishita, Andreas Grothey, Ken McKinnon
We consider regularized cutting-plane methods to minimize a convex function that is the sum of a large number of component functions. One important example is the dual problem obta…
Primal heuristics for Dantzig-Wolfe decomposition for unit commitment
Nagisa Sugishita, Andreas Grothey, Ken McKinnon
The unit commitment problem is a short-term planning problem in the energy industry. Dantzig-Wolfe decomposition is a popular approach to solve the problem. This paper focuses on p…
Use of Machine Learning Models to Warmstart Column Generation for Unit Commitment
Nagisa Sugishita, Andreas Grothey, Ken McKinnon
The unit commitment problem is an important optimization problem in the energy industry used to compute the most economical operating schedules of power plants. Typically, this pro…
On the Effectiveness of Sequential Linear Programming for the Pooling Problem
Andreas Grothey, Ken McKinnon
The aim of this paper is to compare the performance of a local solution technique -- namely Sequential Linear Programming (SLP) employing random starting points -- with state-of-th…
Alternative PV Bus Modelling with the Holomorphic Embedding Load Flow Method
I. Wallace, D. Roberts, A. Grothey +1
The Holomorphic Embedding Load Flow Method (HELM) has been suggested as an alternative approach to solve load flow problems. However, the current literature does not provide any HE…
Optimization-based Islanding of Power Networks using Piecewise Linear AC Power Flow
P. A. Trodden, W. A. Bukhsh, A. Grothey +1
In this paper, a flexible optimization-based framework for intentional islanding is presented. The decision is made of which transmission lines to switch in order to split the netw…
