Energy disaggregation, known in the literature as Non-Intrusive Load Monitoring (NILM), is task of inferring energy consumption each appliance given aggregate signal recorded by a single smart meter. In this paper, we propose novel two-stage optimization-based approach for disaggregation. first phase, small training set consisting disaggregated power profiles used to estimate parameters and sta...

Abstract 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 convex MINLP, extending them to solve nonconvex problems traditionally challenging. The Supporting Hyperplane Optimization Toolkit (SHOT) is a solver based on approximations the feasible set MINLP pr...
