This site-wide search returns results for all documents and events in Tethys Engineering, prioritizing the best matches. Partial word matches are returned (e.g. "engineer" finds "engineering"), but every entered term must be found. If you don't find any results, try reducing the number of words entered or removing special characters. Filters to the right can help narrow your search. Tethys Engineering features an integrated search with other marine renewable energy databases in PRIMRE - click the buttons below "Showing Results for" to search other integrated databases.

… in resource rich deeper more distant waters. The development in these fields is often ahead of policy, regulation and infrastructure. Previous studies often utilise spatial analytics to … make assessments but often overlook grid requirements. In order to address this issue a series of spatial analytic and electrical power flow models have been established to form a novel … power flow dispatch model. It was found that sensitivity analysis was needed at each stage of the modelling process. However, it forms the basis of strategic development tool that could be …

Attention has been drawn to this resource as a number of locations with high tidal current velocity have recently been leased by the Crown Estate for … velocity is too low for any power generation. However, it has been proposed that a portfolio of diverse sites located around the UK will deliver a firm aggregate output due to the relative phasing of the tidal signal around the coast. This paper analyses whether firm tidal power is feasible …

… generators and energy storage are becoming cost competitive. Diesel usually provides about 10% of the demand because most renewables are non-dispatchable and thus the complete decarbonisation … storage and renewable generation capacities. Here a framework for the design and optimisation of HES using wind, wave and solar generation and DSM is introduced. For the Mediterranean it is … has lower benefits because waves act as an energy store for the wind. Thus, the combination of wave energy converters (WECs) and wind turbines significantly reduces the need for backup …
