  • Ocean Power connects wave energy system to grid

    Ocean Power Technologies, Inc. (Pennington, NJ) announced that it has achieved what it claims to be the first-ever connection of a wave-energy system to the power grid in the United States. Ocean Power’s PB40 Powerbuoy system is now delivering power to the grid at the U.S. Marine Corps Base Hawaii on the island of Oahu. The Powerbuoy unit, which was installed in December 2009 at a ...

  • Power quality improvements employing multipulse full-wave AC-DC converters

    In this paper, a set of full-wave AC-DC converters are investigated for power quality improvement in AC mains and DC output. A detailed classification of these full-wave AC-DC converter configurations is made in different transformer connections and several new configurations of isolated and non-isolated full-wave AC-DC converters are developed to meet specific application requirements. The ...

  • Why it`s time to get serious about wave power

    For most of us power from the sea means watching waves crashing on a beach or smashing up against a breakwater. But if you want to experience wave power at its most energetic then you need to be offshore. In fact you need to be over one hundred kilometres offshore. In February 2000, a British oceanographic research vessel sailing in the Rockall Trough, some 180Km from land, encountered the ...

  • 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 ...

  • Supporting wave and tidal energy in the UK - an analysis of UK Policy 2000-2009

    In order to stimulate UK based marine energy technology developers, the UK Government launched the Marine Renewables Proving Fund (MRPF) in 2009. This instrument was designed to bridge the gap between early-stage research funding and the recently-criticised Marine Renewables Deployment Fund (MRDF). This paper develops an analysis framework for policy instruments designed to support technology ...

  • 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 ...

  • Simulation-based evaluation of tidal current power output characteristics

    Tidal current is considered to be one of the promising alternative green energy resources. This paper introduces a simulation based methodology to evaluate tidal current power output characteristics, including capacity factor, and power production variability patterns. Power variability analysis is crucial to grid integration systems design. The proposed methodology is applied to the well known ...

  • Marine energy innovation in the UK energy system: financial capital, social capital and interactive learning

    Innovation activity in marine energy (wave and tidal stream) has been catalysed by a series of recent UK policy initiatives. However, the wider UK energy system remains substantially oriented to market competition and efficiency. As a result, tensions have emerged between recent R&D activity (especially interactive and collaborative learning) and its economic and institutional context. Drawing on ...

  • 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 ...

  • Key issues of tidal energy and factors affecting it globally with civil structures

    This paper focus on some of the key challenges to be met in the development of marine energy, it present prototype form to being a widely deployed contributor to future energy supply of the world. Large-scale wave and tidal current prototypes have been demonstrated around the world, but marine renewable energy technology is still 10-15 years behind that of wind energy. However, having started ...

  • Is marine energy about to go mainstream?

    Why the costs of wave and tidal power could soon plummet - viewpoint from Dr Stephen Wyatt, Head of Technology Acceleration, Carbon Trust As the marine industry gathers in London for its annual get together one thing is clear; the sector is growing up fast.  So fast that it looks like it will soon be defying its critics and getting its feet seriously wet after many years of ...

  • 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 ...

  • Want to Address the Driver Shortage? Get Connected.

    The reasons drivers are giving for leaving fleets and the industry are very similar to why any employee changes jobs: Pay. Respect. Problems with a supervisor. Time away from home. Lack of communication. Bad equipment. No opportunities for advancement. Or the job just isn’t what was expected. But if you look deeper you’ll see that drivers may be saying those are the reasons, but ...
