Solutions Efficient operation of the gas turbine imposes the demand for very high rotational speed of the generator 240,000 rpm. The permanent magnet machine has been chosen as the generator type since this technology is the most promising for high-speed machines: it offers high efficiency and very high power density at low volumes. A high-frequency power converter is required to enable bi-dire...

As energy demands around the world increase, the need for renewable energy sources, such as Micro-Grid (MG) that will not harm the environment has been increased. Micro-Grid has been extensively investigated as a promising solution to energy challenges in 21st century. The optimal generation is one of the important functions for the Micro-Grid operation. It should be noted that supplying therma...

This article presents the concept and mathematical treatment for a techno-economic modelling framework designed to enable exploration of fuel cell micro combined heat and power (micro-CHP) system design and control. The aim is to provide a tool that can help to focus research and development attention on the system characteristics critical for commercial success of these technologies, present c...

Micro-generation has the potential of reducing CO2 emissions from the power sector. This study investigates the emissions performances of some cases of domestic microgeneration during operation. By comparison to the conventional generation options, savings of 10-45% were found, depending on the energy mix. Waste heat recovery by the micro-CHP was found to be the largest carbon saver in this stu...

in this paper smart operation of micro energy hub is presented. energy hub system consists of certain energy hubs and interconnectors that are coordinated by energy hub system operator. an energy hub contains several converters and storages to serve demanded services in most efficient manner from available energy carriers. in this paper, the flexibility of energy delivery point is enhanced u...

Abstract The current study presents the CO 2-eq emissions of operational energy use a single-family house, equipped with micro-cogeneration unit. A back-up boiler and electricity from grid cover remaining demand, not covered by micro-CHP. Two different technologies are evaluated, i.e. ICE fuel cell systems, operating variable share biomethane, while two substrates were considered for biomethane...

With the increasing application of distributed energy resources and information technologies in the electricity infrastructure, innovative possibilities for incorporating the demand side more actively in power system operation are enabled. At the residential level energy costs could be reduced with intelligent price-based control concepts (demand response). A promising, controllable, residentia...
