Test Protocols for Tidal Current Energy Converters

Test Protocols for Tidal Current Energy Converters

ERPE research has impacted the design of protocols for evaluation and comparison of the performance of tidal energy converters. The significant research contribution are:

  • First definition of the significant tidal energy resource around Orkney and Shetland [1].
  • Development of new flux models [2] to more accurately estimate tidal energy resources.
  • Establishing guidelines and protocols to enable accurate comparison of marine energy converters.

Bryden first proposed and justified that there was a significant tidal energy resource in the Fall of Warness, Orkney, catalysing the development of the European Marine Energy Centre (EMEC). The ERPE models and the Significant Impact Factor technique provided a systematic approach to resource assessment for tidal turbines. Borthwick has further confirmed an upper bound of 1.9 GW for the tidal stream power resource of the Pentland Firth [3].

EMEC (with 14 full-scale test berths), testing guidelines arose directly from ERPE research [2] that ultimately was incorporated in protocols for the UK Government £50M Marine Renewables Deployment Fund (MRDF) and then expanded into the FP7 funded Equitable Assessment of Marine Energy Converters (EquiMar) project. The later EquiMar Protocols became the proving metric in the Scottish Government Saltire Prize and were extended further as the basis of the IEC 62600 marine energy standards. "We are very pleased to see the publishing of this Technical Specification of Tidal Device Performance Assessment which will become the basis of Validation Reports for clients. The ERPE team produced the document which is used in the sector and will be taken shortly to the status of a full International Standard." Managing Director, EMEC.

This ERPE research has assisted other marine device test and deployments such as FORCE, Canada. "We are indebted for your strategic assistance with our tidal demonstration. We obtained a road map that led us to a) locating a demonstration site in the Bay of Fundy and b) obtaining environmental consents for a grid-connected facility." Chair, FORCE.
