Validation Of A Simulation Model For A Combined Otto And Stirling Cycle Power Plant, Jim Mcgovern, Barry Cullen, Michel Feidt, Stoian Petrescu

Conference Papers

A project has been underway at the Technological University Dublin (DIT) to investigate the feasibility of a combined Otto and Stirling cycle power plant in which a Stirling cycle engine would serve as a bottoming cycle for a stationary Otto cycle engine. This type of combined cycle plant is considered to have good potential for industrial use. This paper describes work by DIT and collaborators to validate a computer simulation model of the combined cycle plant. In investigating the feasibility of the type of combined cycle that is proposed there are a range of practical realities to be faced and …

Gate 3 Grid Connection Group Processing Approach:An Analysis, John Leahy

Msc. in Energy Management

The aim of this project is to analyse the Group Processing Approach (the “GPA”) to renewable generator grid connections, and in particular the Gate 3 process which is the latest round of the GPA that is currently being implemented in the Republic of Ireland, to determine if it is the most effective approach for connecting new renewable generation. Gate 3 is the third series of the GPA for connecting renewable generation to the Irish Electricity grid where applications are processed in groups or batches. The size of the Gate 3 has bee capped at 3,900MW with applicants being selected based …

Marine Current Energy Devices: Current Status And Possible Future Applications In Ireland, Fergal O'Rourke, Fergal Boyle, Anthony Reynolds

Articles

There is a growing demand for the use of renewable energy technologies to generate electricity due to concerns over climate change. The oceans provide a huge potential resource of energy. Energy extraction using marine current energy devices (MCEDs) offers a sustainable alternative to conventional sources and a predictable alternative to other renewable energy technologies. A MCED utilises the kinetic energy of the tides as opposed to the potential energy which is utilised by a tidal barrage. Over the past decade MCEDs have become an increasingly popular method of energy extraction. However, marine current energy technology is still not economically viable …

Field Monitoring And Hourly Simulation Of Energy And Demand Savings From Use Of The Telkonet Ss5000 System Hotel Ac Occupancy Control, Florida Solar Energy Center, James Cummings

FSEC Energy Research Center®

Air conditioning and heating control systems were installed in a 56-room hotel in central Florida. Thermostat setpoints in half of the rooms were adjusted when the room was detected to be unoccupied. Heating and cooling energy use was monitored for a period of 9.5 months. Energy and demand savings were analyzed.

Solar Water Heating Performance: Use Of Energy Factors, Florida Solar Energy Center, Carol Emrich

FSEC Energy Research Center®

The goal of increasing solar energy installations is widely accepted by all. The Florida Solar Energy Center (FSEC) concluded that the goal of increasing solar hot water system installations in Florida could be greatly enhanced by concentrating its efforts on new construction through simplification of the residential building energy code. Since implementation in 1980, the Florida Energy Efficiency Code for Building Construction has required a calculation procedure that assigns multipliers to residential water heating systems. The multiplier for every water heating system type except solar is based on the system's rated efficiency at standard conditions and is a one- or …

Publications (E)

In today’s electricity generation system, different resources make different contributions to the electricity grid. This fact sheet illustrates the roles of distributed and centralized renewable energy technologies, particularly solar power, and how they will contribute to the future electricity system. The advantages of a diversified mix of power generation systems are highlighted.

Building America Industrialized Housing Partnership (Baihp Ii), Annual Report - Budget Period 4 (Bp4), January 01, 2009 - December 31, 2009, Florida Solar Energy Center, Robert Abernethy

FSEC Energy Research Center®

This annual report summarizes the work conducted by the Building America Industrialized Housing Partnership (BAIHP - www.baihp.org) during the fourth budget period (BP4) of our contract, January 1, 2009 to December 31, 2009. Progress from the three previous budget periods is included for context.

BAIHP is led by the Florida Solar Energy Center (FSEC) of the University of Central Florida. With over 50 Industry Partners including factory and site builders, work was performed in four task areas:

• Task 1: System Evaluations
• Task 2: Prototype House Evaluations
• Task 3: Community Scale Evaluations
• Task 4: Post- Phase 3 Activities.

In Task 1, …

Tidal Energy Update 2009, Fergal O'Rourke, Fergal Boyle, Anthony Reynolds

Articles

Tidal energy has the potential to play a valuable part in a sustainable energy future. It is an extremely predictable energy source, depending only on the gravitational pull of the moon and the sun and the centrifugal forces created by the rotation of the earth-moon system. Tidal energy has been exploited on a significant scale since the construction of the La Rance tidal barrage in France in 1967. A tidal barrage utilises the potential energy of the tide and has proven to be very successful, despite opposition from environmental groups. Kinetic energy can also be harnessed from tidal currents to …

Updated Miscellaneous Electricity Loads And Appliance Energy Usage Profiles For Use In Home Energy Ratings, The Building America Benchmark And Related Calculations [Revised], Florida Solar Energy Center, Danny Parker

FSEC Energy Research Center®

This report addresses the ever increasing percentage of whole house energy use that is attributable to miscellaneous electricity loads (MELs) and major appliances. It builds on earlier U.S. Department of Energy (DOE) reports on the same subject and incorporates the 2005 Residential Energy Consumption Survey (RECS) public use data set to determine how major appliance use is related to the number of bedrooms in existing homes. These data, coupled with existing and proposed DOE appliance testing and labeling standards, are then used to determine a set of baseline lighting and appliance energy end use values for use in the HERS …
