Marine energy - Wave, tidal and other water current converters - Part 100: Electricity producing wave energy converters - Power performance assessment
IEC TS 62600-100:2024 applied in conjunction with the IEC Technical Specification on wave energy resource assessment and characterization (IEC TS 62600-101), provides a method for estimation of the mean annual energy production of a WEC, assessing the electrical power production performance of a single, non-array, wave energy converter, at Location 2 based on the performance at Location 1.
The scope of this document includes:
a) All wave energy converters that produce electrical power from wave energy.
b) All sea resource zones (near and offshore, deep and shallow water).
c) Capture width matrix transposition from one location to another.
d) Limitation on the changes that are allowed to the WEC and the specification of the location.
e) Wave data required at Location 2, as a minimum the requirements found in IEC TS 62600‑101.
f) Development of the capture width matrix at Location 2.
g) Validation of the capture width matrix at Location 2.
h) Assessment of uncertainties in the derived performance parameters at Location 2.
i) Requirements for the allowable power performance transfer by geometric, kinematic and dynamic similarity.
j) Requirements for the allowable incorporation of additional empirical model data.
k) Requirements for the allowable incorporation of additional numerical model data.
l) The document applies to commercial scale wave energy converters that are:
- compliantly moored.
- tautly moored.
- bottom mounted.
- shore mounted.
This second edition cancels and replaces the first edition published in 2012. This edition includes the following significant technical changes with respect to the previous edition:
a) Incorporation of IEC TS 62600-102 as a series of annexes in this document.
b) Removal of the computation of annual energy production. This has been moved to IEC TS 62600-101.
c) Modification to the list of terms definitions, symbols and units.
d) Modification of the reporting section to align with IEC TS 62600-200.
