Welcome to the WEFrance22 International Workshop on Small Wind Turbines

The International Workshop on Small Wind Turbines 2022 is a day-workshop organized by Ampère Laboratory in collaboration with the Wind Empowerment network. This scientific and wind enthusiast gathering aims at raising Small Wind Turbines (SWT) issues from the field to the scientific community, highlight scientific works applicable to the field and finally make connections within the SWT community.

There will be a particular focus on :

  • Field testing of SWT
  • SWT control
  • Microgrids and hybrid systems
  • Power converters
  • Renewable energy and education
  • Rural electrification

This event is part of the Wind Empowerment biannual conference, which is taking place in France from the 8th to the 16th of october 2022. It is open to researchers, practicioners and university students. The event is limited to 40 participants in presence and will be mainly in English and French. The workshop is funded by the AIS department of Ampère Laboratory.


The program


Two presentations sessions will take place in the morning.

Industry panel

# 1 - A brief history of a national small wind turbines test site : SEPEN (fr)
by Bertrand Richer, Eole Conseil

More than 40 wind turbines were tested in the two sites of the SEPEN (Site d'Essai du Petit Eolien National) with many different technologies: horizontal and vertical axis, drag and lift (Savonius vs Darrieus), etc....
Only 58% of the reports have been published, but the absence of publication is also information.
We will try to give some clues to understand why small wind turbine players mostly try to reinvent what has already been tried and which does not work.

# 2 - Small Wind Culture in the energy market and the society (en)
by, Dimitris Christakis, Head of Wind Energy Laboratory, Hellenic Mediteranean Univeristy, Greece

The role of small wind systems in the power systems market is discussed in terms of social and economic criteria. The globalized contemporary economy provides a lot of challenges for the vital goods added value dispersion given the appropriate education and mode of living.

The following questions will be discussed :

  1. Is it possible to provide competitive small wind systems production technology in the frame of a free market?
  2. Who is the user of small wind systems?
  3. How one can configure the right size, price and production method for a potential small wind systems market ?

Academic research

# 1 - Modelling and control of a full scale wind turbine emulator. (en)
by Adrien Prévost, INSA Lyon, Ampère lab
DescriptionThe modelling and control of a full scale Wind Turbine Emulator (WTE) is described for a 700 W rated power residential scale Wind Energy Conversion System (WECS). The differences between the test bench and the physical wind turbine in terms of mechanical parameters are taken into account. Experimental results under static and turbulent wind conditions will be presented.

# 2 - Comparison of several MPPT algorithms on a wind turbine emulator.
by Hiba Houmsi, INSA Lyon, Ampère Lab
Description : An experimental comparison of several maximum power point tracking algorithms have been performed on a wind turbine emulator. The methodology and results will be presented.

# 3 - Open-Source, Modular and Re-programmable Power Converters as building blocks to rural electrification micro-grids ? (en)
by Luiz Villa, University of Toulouse, LAAS-CNRS lab
Description : Power Electronics converters are the building blocks of modern rural electrification micro-grids. They can be used to either manage power flows in DC-DC or DC-AC and they interface batteries, generators, PVs and loads. This presentation shows how can a micro-grid be built and expanded over time from a single power electronics building block. The converter will be explained, together with its different modes of operation. Finally, the OwnTech project will be presented and its perspectives in both field and academic applications.

# 4 - Locally Manufactured Small Wind Turbines for Rural Energy Access: Research, Design and Testing
by Kostas Latoufis, National Technical University of Athens, RURERG
Description : An overview of research activities on various parts of a locally manufactured small wind turbine, such as the blades and rotor, the axial flux permanent magnet generator, the furling tail system, and the overall integration of the small wind turbine in an off-grid system.


The afternoon will start with a visit of Ampère Laboratory and continue with a presentation session about rural electrification and education. We will finish with a "wind dating" session and a feedback session.

Lab visit

Demonstrations of a wind turbine emulator, visits of the microgrid, motor control, power converters rooms.

Rural electrification and education

# 1 - Paths and Obstacles to Energy Entrepreneurship in Rural côte d'Ivoire
Karana Olivier, KOC Bridges to Peace
Description : Renewable energy is seen as the poor man's alternative with solar power widely abandoned for failing to meet local needs. How the introduction of wind power faces an uphill battle in Côte d'Ivoire.

# 2 - Dual Power: Distributed Energy to Meet Local Needs
by Kirk Smith,

Description : "Dual power" is a concept and strategic approach to changing society over time by creating strong, local, community-controlled institutions and infrastructures which increase autonomy with respect to their centralized counterparts. This presentation serves to introduce the concept of "dual power" using the example of localized energy infrastructure such as small-scale distributed wind vs. large-scale centralized on/offshore wind farms.

# 3 - Case study : A rural electrification project in Haïti
Andrew Bowring, Wind Empowerment executive board
Description : The electrification of a school in La Gonave, Haïti, with a locally manufactured small wind turbine will be presented.


Wind dating

A fun activity to make connections between people within the small wind community.


Timetable hours are detailed in the schedule tab.

Getting here

The event will take place on the campus Lyon-Tech la Doua at INSA de Lyon engineering school. The morning will be happening in Gustave Ferrié building, and the afternoon in Léonard De Vinci building for the lab visits, and back to Gustave Ferrié for the rest of the day.

You can take the tramway T1 or T4 and reach Gaston Berger (presentations sessions) or INSA-Einstein (lab visit ). You can plan your trip using TCL website.
