Hybrid Solar Thermophotovoltaic-Biomass/Gas Power Generation System With A Spectrally Matched Emitter For Lower Operating Temperatures, C. M. Iftekhar Hussain Cmih, Brian Norton, Aidan Duffy, Mohamed Oubaha
Conference Papers
Three conceptual designs have been developed for hybrid solar-biomass/gas thermophotovoltaic (TPV) system for a non-intermittent power generation which can operate at relatively low TPV operating temperatures. TPV cells with lower band gap has been chosen for this conceptual hybrid device. The low band TPV cell generates electricity at longer photonic wavelength which corresponds a lower operating temperature. The development methodology is presented for a spectrally matched emitter which emits maximum photonic energy in the 600°C -1000°C temperature range with correspondingly lower photonic energy emission in the 0°C -600°C range. This approach for spectral control in TPV systems requires fewer system …

Conference Papers
Battery Electric Vehicles (BEVs) have been recognised as the ideal solution for lowering the CO2 emissions in the transport sector and helping to achieve a sustainable future. When BEV technology is leveraged with a solar energy source such as a Photovoltaic Charging Station (PV-CS), the CO2 saving potential is extended to both generation and consumption points. Due to the intermittent nature of our solar resource, once the PV-CS is combined with a storage unit, energy production is achieved without risking the disruption to power supply reliability and quality. Technological University Dublin (DIT) has recognised the viability of this …

Conference Papers
Electric Vehicles (EV) have gained interest over the past decade. Accordingly, to support EV technology installation of charging stations are required. A Photovoltaic Charging Station (PV_CS) can generate clean electricity from the sun for charging electric bikes but as can be exposed to harsh weather conditions and faults, which can result in deviations of system characteristics from their normal operating conditions. Reliability of these charging stations is extremely important for supplying adequate charge to EVs, and therefore it must be maintained at all times. This paper presents a systematic approach to electrical reliability issues for PV_CS, by establishing an experimental …

Assessing The Benefits Of Compressed Air Energy Storage On The 2020 Irish Power System, Brendan Cleary, Aidan Duffy, Alan O'Connor, Michael Conlon, Vasilis Fthenakis
Conference Papers
Power systems have evolved as countries implement energy policies focusing on energy efficiency and increased share of renewable energy sources (RES). At the forefront is non-dispatchable generation such as wind and solar. Traditionally power systems were designed for fully dispatchable generating plant. However, these powers systems are under additional pressure due to the variable operational characteristics of RES. Consequently, capital investments in grid reinforcement, interconnection, additional gas generators and smart grid initiatives have been proposed and implemented. Moreover, an increased interest in energy storage technologies has evolved due to their various economic and operational benefits to power systems. Current compressed …
Solar Photovoltaic Water Pumping For Multiple Use Systems (Mus) In Nepal, Fintan Mcloughlin, Aidan Duffy, Michael Conlon
Solar Photovoltaic Water Pumping For Multiple Use Systems (Mus) In Nepal, Fintan Mcloughlin, Aidan Duffy, Michael Conlon
Conference Papers
This paper investigates the performance of five solar photovoltaic (PV) Multiple Use Systems (MUS) used for water pumping. The solar MUS’s provide water for drinking, cleaning and micro-irrigation for some of the poorest communities in Nepal. In the absence of data logging, the performance of each system is investigated based on a series of rules of thumb to determine the predicted, expected and estimated demand and supply of water to small rural communities. The systems are compared based on their technical and economic performance and how this relates to local environmental, physical and socioeconomic characteristics at each location.

Integration Of Upqc For Power Quality Improvement In Distributed Generation Network – A Review, Shafiuzzaman Khan Khadem, Malabika Basu, Michael Conlon
Conference Papers
In this paper a technical review of the integration of a Unified Power Quality Conditioner (UPQC) in a distributed generation network is presented. Although the primary task of UPQC is to minimize grid voltage and load current disturbances along with reactive and harmonic power compensation, additional functionalities such as compensation of voltage interruption and active power transfer to the load and grid have also been identified. Connection methodologies with their advantages and disadvantages are also described. Recent improvements in capacity expansion techniques and future trends for the application of UPQC in distributed modes are also identified.

The Generation Of Domestic Electricity Load Profiles Through Markov Chain Modelling, Aidan Duffy, Fintan Mcloughlin, Michael Conlon
Conference Papers
Micro-generation technologies such as photovoltaics and micro-wind power are becoming increasing popular among homeowners, mainly a result of policy support mechanisms helping to improve cost competiveness as compared to traditional fossil fuel generation. National government strategies to reduce electricity demand generated from fossil fuels and to meet European Union 20/20 targets is driving this change. However, the real performance of these technologies in a domestic setting is not often known as high time resolution models for domestic electricity load profiles are not readily available. As a result, projections in terms of reducing electricity demand and financial paybacks for these micro-generation …

Thermodynamic Modelling And Ray-Trace Modelling Of Luminescent Solar Concentrators: A Comparison Of The Two Approaches, Manus Kennedy, Amanda Chatten, Daniel Farrell, Rahul Bose, Andreas Büchtemann, Sarah Mccormack, John Doran, Brian Norton, Keith Barnham
Conference Papers
The electrical and spectral output from luminescent solar concentrator (LSC) devices is predicted using thermodynamic modelling and ray-trace modelling techniques. Predicted output from four LSCs of varying dimensions, containing different luminescent dyes, are found to be in good agreement with measured output taken from fabricated LSCs. Despite the many different processes involved in the two modelling approach, predicted short circuit current densities from both approaches are found to be in excellent agreement.
