Power control strategy for grid connected permanent magnet synchronous generator of a distributed generation unit
This paper describes the studies on the operation and control of a variable speed wave energy conversion system. The wave energy conversion system considered is oscillating–water–column (OWC) based Wells turbine driven permanent magnet synchronous generator connected to the grid by means of fully controlled frequency converter. In such systems primary aim is to achieve a low distortion, high ...

A binary ACO for controlling all–electric power take off system in wave energy converters
This paper describes a metaheuristic algorithm for controlling all–electric power take off (PTO) system of wave energy converters. It provides optimal parameter values to the controller following the instantaneously changing sea state. The output of the algorithm is used to tune the electrical control systems in the PTO system in order to provide sufficient time for the point absorber to achieve ...

A novel particle swarm optimisation self-regulating stand-alone wave energy conversion scheme
The paper presents a novel stabilisation scheme system for a wave energy converter (WEC) using permanent magnet linear generator (PMLG) connected to a six-pulse diode rectifier. The proposed controller of WEC-battery renewable energy system is based on multi-objective particle swarm optimisation (MOPSO) technique. The optimisation algorithm is implemented to control a novel low cost dynamic AC ...

Research and development in ocean energy technologies
The volatile fuel prices for electricity generation, elevated concerns about global warming and energy security has prompted countries to look for alternative energy sources. One of the alternative energy sources is ocean energy. Currently, there is few ocean energy technologies that are commercially available to harness electrical energy from ocean despite the fact that ocean covers more than ...

Oceans of Energy
Technologies that harness the energy of moving water or temperature differentials in the oceans promise to deliver abundant carbon-free electricity. Long before humans got hooked on fossil fuels, we learned how to harness the power of water to do work. Rivers ran mills that ground flour, sawed logs or spun looms that transformed fibers into textiles. Later generations realized that moving water ...

Unique Full-Scale PTO System Bi-Directional Wind Tunnel Test Facility - Case Study
Wave energy converters are generally placed in a very harsh environment and are hard to access due to their location and/or unfavorable weather conditions. With this in mind a full-scale wind tunnel test facility capable of simulating a variety of wave heights and wave periods has been built to fully test and validate Aquanet's full-scale 1MW rated capacity Power Take-Off system (PTO). The unique ...

AOPS Are Going to Help Transform the Ocean Economy, but What are They?
From electric vehicle charging stations appearing everywhere to the drones Amazon is using to deliver packages in some markets, it is easy to see the electrification transformation that’s occurring on land. But the ocean is out of sight and out of mind, which is why many people don’t know what’s happening in the busy, multitrillion dollar economy operating out there. ...

Transformational low carbon subsea project showcased at industry event
A successful showcase of the renewable remote power and communications system for the Renewables for Subsea Power (RSP) project was held this month in Dyce, Aberdeen. Hosted by Verlume and supported by project partners Baker Hughes, Mocean Energy and Transmark Subsea AS, the event was an opportunity for around 30 invited guests from across the subsea sector to see the onshore commissioning of ...

Santa Fe company aims to turn motion of waves into electricity
A Santa Fe company plans to turn ocean waves into electricity off Peru’s coast in the spring. Atmocean is run by Philip Kithil, an entrepreneur and inventor. Chris White, a native Santa Fean, works as the project administrator, and both understand the ocean and waves better than most landlocked New Mexicans. “There are a lot of exciting advantages here versus traditional ...

Ocean exergy and energy conversion systems
Oceans store energy in the form of currents, waves, tides, heat and salinity that can help to alleviate worldwide demand for power and the global climate change threat. They also store a considerable amount of an isotope of hydrogen (deuterium) which takes part in the most promising fusion reactions. Exergy analysis can be applied to evaluate the work potential (extractable) of a resource. This ...

2014 JRC Ocean Energy Status Report
Abstract Oceans and seas have the potential to play a significant role in providing clean energy. Different technologies are currently being developed to ensure a long term contribution of ocean energy to the future energy system. Among the different ocean energy technologies, tidal and wave conversion systems are expected to contribute the most to the European energy system in the short to ...
