  • selection of Prime Mover for combined cooling heating and power systems based on energy savings life cycle analysis and environmental consideration
    Energy and Buildings, 2016
    Co-Authors: Kibria K Roman, Jedediah B Alvey
    Abstract:

    Abstract Selection of Prime Mover Type was investigated for use in combined cooling, heat and power systems. Selection was determined from comparison of performance criteria for economic, energy and emissions savings. Simulations were run for three different Types of Prime Movers in one climate zone and compared to a reference case with a typical separate heating and power system in the same climate zone. A hybrid load following method was implemented, with a suggested improvement. Performance parameters were compared and results indicated emissions and energy savings for all three Prime Movers. The Prime Mover Types were reciprocating internal combustion engine (ICE), micro-turbine and phosphoric acid fuel cell. The climate zone was chosen to be a cold, humid climate represented by Chicago, IL. Economic savings were seen for both the ICE and micro-turbines. Emissions savings for carbon, nitrogen-oxides and methane, for all three Types, were greater than 9%, 12%, and 13%, respectively. Primary energy consumption savings for all three were greater than 8%.

  • Distributed Generation Interface to the CERTS
    2010
    Co-Authors: H Nikkhajoei, R. H. Lasseter
    Abstract:

    Abstract — This paper focuses on the energy storage system and the power electronic interface included in microsources of the CERTS microgrid. To provide the plug-and-play feature and the power quality requirements of the CERTS microgrid, all microsources regardless of their Prime Mover Type must have a unified dynamic performance. This necessitates attaching an energy storage module to some or all of the microsources. The storage module is attached to the Prime Mover through a power electronic interface that couples the microsource to the microgrid. Details of the energy storage module, the power electronic interface and the corresponding controls are described. Performance of an example microsource, which includes a synchronous generator, a storage module and an electronic interface, is studied. Dynamic performance of the example microsource when operating in the CERTS microgrid is evaluated based on digital time-domain simulations in the EMTP-RV software environment. Effectiveness of the storage module, the electronic interface and the corresponding controls in enhancing the microsource performance is verified

  • Distributed generation interface to the CERTS microgrid
    IEEE Transactions on Power Delivery, 2009
    Co-Authors: H Nikkhajoei
    Abstract:

    This paper focuses on the energy storage system and the power electronic interface included in microsources of the CERTS microgrid. CERTS stands for the Consortium for Electric Reliability Technology Solutions. The consortium was formed in 1999 to research, develop, and disseminate new methods, tools, and technologies to protect and enhance the reliability of the U.S. electric power system and efficiency of competitive electricity markets. To provide the plug-and-play feature and the power quality requirements of the CERTS microgrid, all microsources regardless of their Prime Mover Type must have a unified dy- namic performance. This necessitates attaching an energy storage module to some or all of the microsources. The storage module is attached to the Prime Mover through a power electronic interface that couples the microsource to the microgrid. Details of the energy storage module, the power electronic interface and the corresponding controls are described. Performance of an example microsource, which includes a synchronous generator, a storage module and an electronic interface, is studied. Dynamic perfor- mance of the example microsource when operating in the CERTS microgrid is evaluated based on digital time-domain simulations in the EMTP-RV software environment. Effectiveness of the storage module, the electronic interface and the corresponding controls in enhancing the microsource performance is verified.

  • a general technoeconomic and environmental procedure for assessment of small scale cogeneration scheme installations application to a local industry operating in thrace greece using microturbines
    Energy Conversion and Management, 2005
    Co-Authors: P A Katsigiannis, D P Papadopoulos
    Abstract:

    Abstract The present paper describes a proposed general systematic procedure for small-scale combined heat and power (CHP) exploitation (where “small-scale CHP” refers to CHP installations with electric capacities up to 1 MW). The mentioned systematic procedure is implemented through a developed computer code and may be applied to any such small-scale project in order to assess its suitability based on technoeconomic and environmental considerations. A dynamic database based on small-scale CHP units (available in the world market) and their pertinent technical, economical and environmental features is created and, in conjunction with the developed program, is used for determination of a suitable CHP unit (or system) size and the selection of the associated proper Prime Mover Type for any project of interest. Using well-known economic criteria, the economic analysis is performed, including the sensitivity analysis of the considered project based on the main key system parameters. In terms of the socioeconomic analysis, a carbon tax (CT) scenario is considered, and its effect on the economic behavior of the project is investigated. Last, with respect to environmental considerations, the program calculates, for any such project, the avoided main pollutants and the fuel savings when a CHP system is applied. As a case study, a small textile industry operating in the Eastern Macedonia-Thrace Region of Greece is considered, and its associated (electrical and thermal) data are used as input data to the proposed computer program. In this application, two microturbine units are selected and thoroughly evaluated, and the pertinent simulation results are presented and discussed accordingly.
