Electricity swing options represent a special kind of American-style path dependent power derivatives. Thus, valuation of a swing option is inevitably linked to the determination of an optimal excercise strategy up to the end of the option's exercise perio ...

In this paper the short term scheduling optimization of a combined cycle power plant is accomplished by exploiting hybrid systems, i.e. systems evolving according to continuous dynamics, discrete dynamics, and logic rules. Discrete features of a power plan ...
A more widespread usage of heat pumps would contribute to significantly reduce both local and global environmental impacts. This is particularly relevant within cities, where advanced integrated energy systems incorporating heat pumps and associated with d ...
The effects and the consequences of transferring the ignition point of the conventional combustion chamber into a small unscavenged prechamber were evaluted through a numerical simulation based on the CFD-code KIVA- 3V. The prechamber flow characteristics ...
An integrated microreactor system for the direct dehydrogenation of methanol to water-free formaldehyde was developed. The endothermic reaction can be homogeneously catalyzed with evapd. sodium. At reaction temps. of up to 1100 K nearly complete conversion ...
The implementation of integrated energy systems within urban areas is a promising CO?2 emissions abatement measure. In this paper on-site heating, cooling and power generation based on a solid oxide fuel cell and gas turbine (SOFC-GT) combined cycle unit a ...
In a first paper (part I), prechamber ignition in cogeneration natural gas engines has been shown to significantly intensify and accelerate the combustion process, offering a further potential to reduce the exhaust gas emissions while keeping efficiency at ...
A small cogeneration system based on a Solid Oxide Fuel Cell (SOFC) fed on the renewable energy source biogas is presented. An existing farm biogas production site (35 m3 per day), currently equipped with a SOFC demonstration stack, is taken for reference. ...
The operation of the small size cogeneration gas engine (6 cylinders, 122mm bore, 142mm stroke) modified for unscavenged prechamber ignition was experimentally investigated. The objective was to evaluate the potential to reduce the exhaust gas emissions, p ...
In this paper the load optimization of a combined cycle power plant under consideration of the real cost of lifetime usage is accomplished by exploiting hybrid systems, i.e., systems evolving according to continuous dynamics, discrete dynamics, and logic r ...
