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...

At present there is an ongoing process within the EU on how to fulfil the commitment made to the Paris agreement. The role of hydrogen, and in particular hydrogen from natural gas combined with capture and storage of the produced CO₂ (CCS), is debated. The hydrogen for Europe pre-study has been...

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...
