Assessing The Economic Benefits Of Compressed Air Energy Storage For Mitigating Wind Curtailment, Brendan Cleary, Aidan Duffy, Alan O'Connor, Michael Conlon, Vasilis Fthenakis

Other resources

Renewable energy generation in the All-Island of Ireland (AII) is set to increase by 2020 due to binding renewable energy targets. To achieve these targets, there will be periods of time when 75% of electricity will be generated mainly from onshore wind. Currently, the AII system can accommodate a 50% maximum permissible instantaneous level of wind generation. The system operators must make system wide wind curtailment decisions to ensure this level is not breached. Subsequently, the ability to limit wind curtailment using large scale energy storage such as pumped hydroelectric energy storage and compressed air energy storage (CAES) is increasingly ...

Determination Of Area Of Fire Origin Through Examination Of Structural Failure And Deformation, Andrew Thomas Tinsley

Doctoral Dissertations

The effects of fire on steel have long been noted and studied. However, a scientific connection between the area of origin for a fire and the amount of steel deformation observed at the scene has never been established. The development and implementation of this type of analysis has the potential to decrease investigation times significantly as the types of structures to which this method would be applicable are typically large, expansive structures. In order to investigate the relationship between structural steel deformations and a fire’s origin, a series of six tests were performed in a smaller size portal frame ...

Optimised Integration Of Grid-Connected Renewable Energy Technologies For Domestic Application In Ireland, Zhe Li [Thesis]

Doctoral

The utilisation of renewable energy resources for electricity and thermal generation is extremely important in Ireland due to the lack of indigenous fossil fuel resources and the high dependence on imported fossil fuels. The release of environmentally-damaging greenhouse gases in the combustion of fossil fuels in electricity and thermal generation is also a major issue. In Ireland, the domestic dwelling is recognised as one of the biggest energy consumers. The use of renewable energy technologies to provide electricity, heating and hotwater can effectively offset the usage of fossil fuels. The aim of this research study was to develop a novel ...

Shock Pulse Filtering Evaluation On Package Size And Cost, Matthew P. Daum Ph.D.

Journal of Applied Packaging Research

Distribution packaging design often relies on cushion curves to determine required material thickness needed for product protection during shipment. The material thickness chosen based on cushion curves establishes overall package size, a key determiner of logistics costs. Cushion curves are constructed by dropping a mass onto a cushion, and interpreting the resulting shock pulse deceleration. The reported deceleration can be highly influenced by applying a “filter” to the shock pulse, a useful standar d prac - tice that removes unwanted high frequency elements superimposed on top of the basic shock pulse shape. Standard test methods for generating cushion curves generally do ...

Automated Image Interpretation For Science Autonomy In Robotic Planetary Exploration, Raymond Francis

University of Western Ontario - Electronic Thesis and Dissertation Repository

Advances in the capabilities of robotic planetary exploration missions have increased the wealth of scientific data they produce, presenting challenges for mission science and operations imposed by the limits of interplanetary radio communications. These data budget pressures can be relieved by increased robotic autonomy, both for onboard operations tasks and for decision- making in response to science data.

This thesis presents new techniques in automated image interpretation for natural scenes of relevance to planetary science and exploration, and elaborates autonomy scenarios under which they could be used to extend the reach and performance of exploration missions on planetary surfaces.
