Germany has set itself some very ambitious targets for energy supply from renewable sources, including 80% of electricity by 2050. The favourable economic political framework for renewable technologies has led to the rapid expansion of onshore wind and other renewables in the past years....

Cogeneration of heat and electricity constitutes an important pillar in energy and climate policy. The optimal dimensioning and operation of residential micro-combined heat and power (mCHP) systems is an important area of ongoing research, especially because these systems are prohibitively...

Improvements in the building stock insulation and the replacement of heating systems will have to take place within the next decades in order to lower heat demand and the associated carbon emissions of the building sector. The current study presents an integrated, iterative modelling approach to...

A tool for long-term optimization of cogeneration systems is developed that is based on mixed integer linear-programming and Lagrangian relaxation. We use a general approach without heuristics to solve the optimization problem of the unit commitment problem and load dispatch. The possibility to...
