The over-arching project objective is to fully develop and validate optimal controls frameworks that can subsequently be applied widely to different WEC devices and concepts. Optimal controls of WEC devices represent a fundamental building block for WEC designers that must be considered as an integral part of every stage of device development. Using a building-blocks approach to optimal controls development, this effort will result in the full development of a feed-forward and feed-back control approach and a wave prediction system. Phase I focused primarily on numerical offline optimization and validation using wave tank testing of three industry partners? WEC devices, including CalWave, Ocean Energy, and Resolute Marine Energy. These industry partnerships allowed us to identify optimal control strategies for these different WEC topologies at different maturity levels. Phase II focused on demonstrating an integrated control system on a custom-built prototype for at-sea testing. A secondary focus during phase II is to adapt our systems identification, controls and wave-prediction frameworks to become more robust and comprehensive in respect to capability, robustness, and reliability. RE Vision Consulting leads this project and has compiled the final public domain report included in this submission.

This dataset includes data from the Monterey Bay Aquarium Research Institute (MBARI) wave energy converter (WEC) and a nearby located Sofar Spotter buoy. The Monterey Bay Aquarium Research Institute has developed and deployed a small two-body point absorber wave energy device suitable to autonomous underwater vehicle, sensor system, and even aquaculture farm needs. For more information on the MBARI WEC see the research journal attached in the submission.

Updated Risk Registers for major subsystems of the StingRAY WEC completed according to the methodology described in compliance with the DOE Risk Management Framework developed by NREL.

This submission includes documentation on the Modular Ocean Instrumentation System (MOIS) installation on the Azura 1/2 scale wave energy converter at the Marine Station Kaneohe Bay (MCBH). Data from the deployment will be uploaded over the course of the test. The instrumentation and data come from the NREL team participating in this testing.

The TidGen Power System generates emission-free electricity from tidal currents and connects directly into existing grids using smart grid technology. The power system consists of three major subsystems: shore-side power electronics, mooring system, and turbine generator unit (TGU) device. This submission includes a technical report on control system development, supporting simulations and supervisory control and data acquisition (SCADA) system requirements. Also included is the final design of the control and SCADA system, with supporting simulations and risk mitigation control strategies to address major system technical risks.

Collaborative effort between AquaHarmonics, Sandia National Laboratories (SNL), and the National Renewable Energy Laboratory (NREL) to revise and validate Aquaharmonics' full wave to wire model, allowing for reduced uncertainty and increased understanding of design requirements of a utility scale wave energy converter (WEC). SNL and NREL in collaboration with AquaHarmonics, will set up and run WEC Simulator (WEC-Sim) models of the AquaHarmonics WEC, building off past model developments for inclusion of custom PTO (power take-off) dynamics. The intent is to review, update, and verify or validate a new WEC-Sim model against wave tank experimental data. Furthermore, the WEC-Sim model will be coupled to an energy storage system model to better understand the wave-to-wire functionality. This data set is described in the "Test Log" excel file. Please refer to that document for details on each specific test date/time, constraint parameters and model hardware setup details. Sim model can be found in the associated MHKDR link below.

The purpose of this quarterly report is to release a progress report immediately, while the final report and remaining project items await release before the moratorium date.

Final Technical Report for "Advanced Controls for the Multi-pod Centipod WEC device" describing project parameters, organization, task activities, accomplishments, and conclusions. See other submissions under this DOE project for economic viability, design geometry, and modeling.

The objective of this project is to advance the Technology Readiness Level of the x1 Wave Energy Converter (WEC) developed by CalWave Power Technologies Inc. through advanced numerical simulations, dynamic hardware tests, and ultimately a scaled open water demonstration deployment. Key outcomes include deployment and operation of the demonstration unit at an open water site which replicates full scale ocean conditions, and performance and load measurements which are used to validate the high techno-economic performance of the full-scale device. This report briefly describes the x1's final system design but, as a final test report, mainly focuses on the open water testing. For further description of the WEC system the reader is referred to CalWave's system content models, which will become publicly available at the end of 2027. The full version of this Final Test Report will become available on 8/10/2028. This WEC pilot project was done at Scripps in San Diego, California, USA.
