Steam injection for power and efficiency augmentation in aeroderivative gas turbines has been commercially established for natural gas-fired cogeneration since 1980. Steam-injected gas turbines fired with coal and biomass are being developed. A performance and economic assessment of biomass integratedgasifier steam-injected gas turbine (BIGISTIG) cogeneration systems is carried out here. A deta...

The development of Enhanced Geothermal Systems (EGS) for the cogeneration of electricity and district heating has recently gained interest, and is expected to know an important development in the future. Major research questions on the design of the energy conversion system concern the increase of the efficiency in the usage of geothermal resources, as well as the increase of their economic pro...

Proton exchange membrane fuel cells (PEMFCs) are highly efficient power generators, achieving up to 50-60% conversion efficiency, even at sizes of a few kilowatts. PEMFCs have zero pollutant emissions when fueled directly with hydrogen, and near zero emissions when coupled to reformers. These attributes make them potentially attractive for a variety of applications including electric vehicles a...

Photovoltaic-thermal (PVT) technology refers to the integration of a photovoltaic (PV) and a conventional solar thermal collector, representing the deep exploitation and utilization of solar energy. In this paper, we evaluate the performance of a solar PVT cogeneration system based on specific building energy demand using theoretical modeling and experimental study. Through calculation and simu...

The absolute necessity of a stable and uninterrupted power supply within hospitals makes many of these facilities uniquely suited to cogeneration plants. Hamilton Health Sciences recently completed the largest hospital cogeneration project ever undertaken in the country. Spanning three acute care hospitals and generating a combined total of 22.75 megawatts of electricity, Hamilton Health Scienc...

In this paper, the method of rationally determining the system structure and operational strategies is proposed for the energy supply system for a hospital based on the optimization approach. First, energy demands are estimated hourly, daily, and seasonally through one year for the hospital with total floor area of 25,000 m. Second, miscellaneous kinds of equipment are listed up such as refrige...

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...
