This paper concerns the assessment of two methods for convex relaxation of the short-term hydrothermal scheduling problem. The problem is originally formulated as a mixed integer programming problem, and then approximated using both Lagrangian and Linear relaxation. The two relaxation methods are...

This paper presents a framework for long-term price forecasting in hydro-thermal power systems comprising two modeling layers. A long-term hydro-thermal model expresses the expected future cost as a function of hydro reservoir levels to a short-term operational model. The short-term model re...

In order to quantify a set of scenarios for the European and Norwegian energy system, a set of two linked models is applied. These comprise a global assessment model and an expansion model for the European power system. This setup of linked model allows to apply global framework developments in...

A linear complementarity model is developed and presented for two different electricity market designs comprising an energy-only as well as a capacity market. In addition, storage units are implemented, assessing the impact of the market design on these units. Results of a case study for northern...
