The building sector is one major primary energy consumer and pollutant emission source. In recent years, the building-related research studies on the potential use of Maisotsenko-cycle in energy systems have been increasing in recent years. The growing interest lies in its expanded applications beyond the air-conditioning systems (the main “energy consumers” in buildings) into the prime movers (the key players in power generation). In order to evaluate its application merits in the practical tri-generation system of the urban districts, an extensive computer simulation platform has been developed. Based on a case study, this paper describes the techniques in the mixed use of numerical tools in performing system optimization studies for distributed power application on a university campus site. The practicality of the methodology is demonstrated through a hypothetical tri-generation system primed with Maisotsenko combustion turbine cycle. The findings are very much interesting.

According to the methods of focusing,the solar thermal generation can be classified to tower system,parabolic trough system and dish-stirling system. The parabolic solar thermal generation system is an important type of solar thermal utilization. Compared to tower and dish-stirling system,the parabolic trough system has many advantages such as the small concentration ratio,the simple process,the low material requirement and the simple tracking device because of many concentrator on-axis tracking. The parabolic trough system is the lowest cost, least close to commercialization,larger potential system optimization,and the most suitable to large operation in this three thermal generation systems [1,. The parabolic trough system is composed of concentrator and receiver,and the receiver is the key component that uses solar energy to heat working fluids in receiver. Therefore,the key problem is how to make the solar energy transfer to subsequent generation system efficiently and stably.

Power Generation System

In this paper, a biogas fuelled power generation system is considered. The system is based on a molten carbonate fuel cell stack for electricity generation, coupled with a PSA for hydrogen production. The power generation system is about 500 kW and consists of a fuel cell integrated with a micro gas turbine and a steam reformer. A design model of the system is presented. A thermoeconomic analysis is performed with the objective of highlighting the critical processes in terms of low efficiencies or high cost of components and to improve the initial design. The main design parameters affecting the critical process are identified and a system optimization is performed in order to minimize the unit cost of electricity produced by the system. The analysis presented here is the first result of a three year project (BIOH2POWER), which aims to produce and test the system.
