Stand-alone Microgrids – A major Asset for the Electrification of Off-grid Sites

January 30, 2018

  • Technical content: Karim Belmokhtar, Cédric Arbez, Kossivi Tete, Marilys Clément

    Authors: Lucie Fauteux, Karim Belmokhtar

    Both in Canada and in other countries, operating thermal power plants to produce electricity for off-grid sites results in high energy costs as well as greenhouse gases, which are a major concern for the international community. In this context, the deployment of stand-alone microgrids integrating different sources of renewable energy stands out as a promising solution.
    At the dawn of the energy transition already being undertaken by numerous jurisdictions, the TechnoCentre éolien draws on its expertise to provide an accurate synopsis of the situation and to present Opten, a bold research program aimed at sustainably integrating renewable energy into microgrids.

    - Overview of microgrids
    - Development potential and technical, economic & social challenges

Icing Climate and Productivity: Choosing the Right Sensor

September 14, 2017

  • Technical Content: Cédric Arbez, Charles Godreau, Kossivi Tete, Marilys Clément

    Authors : Lucie Fauteux, Marilys Clément

    Harnessing wind regimes in cold climates presents important challenges, notably due to the risk of ice accretion on wind turbine components. Detecting ice events is therefore crucial to ensure the profitability and the safety of installations, but what about the performance of the sensors available on the market?

    As a leader in renewable energy integration and wind farm optimization, the TechnoCentre éolien recently published a paper that proposes a performance assessment methodology for meteorological sensors exposed to icing conditions.


    • Icing recap;
    • Quantitative performance assessment for meteorological sensors in icing conditions;
    • A reliable performance index that can be used to optimize wind farm profitability.

Development and Validation of an Ice Prediction Model for Wind Farms

August 17, 2017

  • Coordinators: Cédric Arbez, Matthew Wadham-Gagnon

    Authors: Marilys Clément, Charles Godreau, Nigel Swytink-Binnema, Kossivi Tete

    This report presents the results of a study on the validation of the GEM-LAM-Jones-Makkonen (GLJM) model for meteorological icing forecasting that was commissioned by Natural Resources Canada.

    This model is based on the pairing of the GEM-LAM weather forecasting model developed by Environment Canada (EC) with those models designed by Jones and Makkonen to predict icing accretion. The objective of this validation is to assess the capacity of the GLJM model to predict icing episodes at wind farms and the associated production losses.

Study – Ice Induced Vibrations in Wind Turbines

March 15, 2013

  • Presented at WinterWind 2013


    Authors : Ville Lehtomäki, Matthew Wadham-Gagnon, Dominic Bolduc, Bruno Boucher, Simo Rissanen, Timo Karlsson, E. Bechoefer

    The TechnoCentre éolien, VTT Technical Research Centre of Finland and NRG Systems joined forces to determine if wind turbine vibrations could be caused by ice.

Study – Ice Profile Classification

March 15, 2013

  • Presented at WinterWind 2013


    Authors : Matthew Wadham-Gagnon, Dominic Bolduc, Bruno Boucher, Amélie Camion, Jens Petersen, Hannes Friedrich

    The TechnoCentre éolien conducted a study, in collaboration with REpower Systems, dealing with ice build-up on wind turbines blades which led to the development of a method that can be used to classify the severity of icing events. The methodology developed along with meteorological and production data could lead to a more thorough understanding and/or validation of weather forecasting, wind turbine blade ice accretion models, ice protection systems and ice-induced vibration in wind turbines.
