Solar Photovoltaic Water Pumping For Multiple Use Systems (Mus) In Nepal, Fintan Mcloughlin, Aidan Duffy, Michael Conlon Sep 2013

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.


Maximising Value Of Electrical Networks For Wave Energy Converter Arrays, Fergus Sharkey, Elva Bannon, Michael Conlon, Kevin Gaughan Sep 2013

Maximising Value Of Electrical Networks For Wave Energy Converter Arrays, Fergus Sharkey, Elva Bannon, Michael Conlon, Kevin Gaughan

Articles

Currently there are the beginnings of a commercial wave energy industry and the ultimate ambition will be to deploy Wave Energy Converters (WECs) in arrays, or wave farms, in a similar fashion to offshore wind. These arrays will require electrical networks to collect and export the generated electrical power to shore and onto the electrical grid. For large scale wind farms the inter-array and export electrical networks can represent more than 20% of the project’s capital expenditure. Submarine power cables account for a large proportion of this cost. The same is expected to be the same for WEC arrays.

Impacts On The Electrical System Economics From Critical Design Factors Of Wave Energy Converters And Arrays, Fergus Sharkey, Michael Conlon, Kevin Gaughan Sep 2013

Impacts On The Electrical System Economics From Critical Design Factors Of Wave Energy Converters And Arrays, Fergus Sharkey, Michael Conlon, Kevin Gaughan

Conference papers

It is expected that ultimately, like offshore wind farms, electrical systems will make up to a quarter of the overall Capex of wave farms. This is a significant element of cost and consideration must be taken in the design of both individual wave energy converters (WECs) and arrays of WECs to ensure that these costs can be minimised. In a worst case scenario design decisions could increase the cost of the electrical system by several orders and ultimately make the technology uncompetitive.

This paper outlines the impacts on the cost of the electrical system arising from design factors of WECs …


Resource-Induced Voltage Flicker For Wave Energy Converters – Assessment Tools, Fergus Sharkey, Joe Macenri, Elva Bannon, Michael Conlon, Kevin Gaughan Aug 2013

Resource-Induced Voltage Flicker For Wave Energy Converters – Assessment Tools, Fergus Sharkey, Joe Macenri, Elva Bannon, Michael Conlon, Kevin Gaughan

Articles

For wave energy converters, the input resource has a typical period of 5–20 s depending on the site location and dominant seastates. Wave energy converters generally produce mechanical power twice per wave cycle and therefore depending on the storage available, the electrical power output has half the period of the input resource. These regular power changes induce a voltage change at the point of connection (POC) which is proportional to the amplitude of the power change and at the same frequency. Therefore the coupling of the input resource to the output power of a wave energy converter will cause voltage …
