Title: Fuzzy Logic as a Method to Optimize Wind Systems Interconnected with the Grid
Issue Date: 2010
Abstract: The wind systems have become more and more complex, namely due toincrease of the turbines and wind farms power, what implies higher significance ofeither system non-linearities or system multivariable characteristics. It adds asdirect consequence from wind systems high power that wind farms are becomingactive elements in the wind power system. So the wind system performance andbehaviour become critical elements of the grid. The performance of the turbinecontrol is improved keeping on the power coefficient always near to maximumvalue, optimizing the energy extraction from the wind speed and so increasing theglobal system efficiency. It adds that the operation within a wind farm contextdemands for optimization of the whole operation. This chapter analyses windsystems biased by the increasing of wind power penetration into the grid and intendsto deal with the requirement of controlling either each wind system or windfarm pointing out a methodology to design fuzzy controllers in order to optimizeturbine operation and farm operation taking in accounting its operation as powersystem element. Some results are carried out to validate main conclusions, namelythe need of including in the control process data on very short-term wind conditionthrough adopting new techniques of real-time forecasting.
