Wind Turbines to Improve Efficiency by Acting More Like Humans?

Wind Turbines to Improve Efficiency by Acting More Like Humans?

Most turbines are designed to produce maximum allowable power once winds reach a certain speed, called the rated speed. In winds above or below the rated speed, control systems can make changes to the turbine system, such as modifying the angle of the blades or the electromagnetic torque of the generator. These changes help keep the power efficiency high in low winds and protect the turbine from damage in high winds. Many control systems rely on complex and computationally expensive models of the turbine’s behavior, but the Chinese group decided to experiment with a different approach. The researchers developed a biologically inspired control system, described in the American Institute of Physics’ Journal of Renewable and Sustainable Energy , that used memory of past control experiences and their outcomes to generate new actions. In simulations, the controller showed initi...
