A two day workshop on control systems design for wind power generation is to be held during May 2011 in Glasgow. This is intended to provide a tutorial introduction to the control techniques involved in wind turbines and also an overview of the current state of the art. The workshop is organised by ISC Ltd., which is one of the leading partners in European Union supported project AEOLUS on offshore wind farm control. Other members of this project will contribute to the event.

The level of the workshop will be introductory with demonstrations so that engineers really appreciate the techniques described. However, it will also provide a tutorial overview of the research in offshore wind energy systems aimed at reducing breakdowns and limiting maintenance costs.

The first half day of the two day workshop will be concerned with basic control engineering design techniques needed in wind turbine control systems for either individual wind turbine or wind farm control. The second half day will include the design of controllers for individual wind turbines and the wider aspects of wind farm control. The second day will cover coordinated supervisory control of wind farms and will report on the advances made in the EU programme. The first day of the event will therefore mostly introduce control design methods for individual regulating loops, describing the advantages and benefits. The second day will concern the main problems and difficulties in onshore and offshore wind farm control.

Day 1

The material included in day one involves:

  • Modelling and simulation of nonlinear systems
  • PID control for regulating loop control design
  • Disturbance rejection (LQG design)
  • Nonlinearities (NGMV design toolbox)
  • Predictive control for supervisory systems
  • Design issues including the effects of delays and robustness.

Day 2

The second day will cover the following topics:

  • The problems of reliability and fatigue in offshore wind farm control
  • Robustness, monitoring and reconfiguration
  • Optimising the performance of offshore wind farms
  • Supervisory predictive control for wind farms
  • Distributed versus centralized control
