浮体式洋上ウィンドファームにおける総発電量の調整を考慮した分散ブレードピッチ角制御

抄録

In this paper, we consider a distributed control approach for blade pitch control of a wind farm which consists of several floating offshore wind turbines. Each wind turbine is modeled as a discrete-time linear model based on the aerodynamics simulator for wind turbines called FAST (Fatigue, Aerodynamics, Structures, and Turbulence). We formulate an optimization problem with an objective function of a quadratic form to coordinate a total power generation determined by a Transmission System Operator (TSO) while keeping fluctuation of the generator speed and oscillation of each wind turbine sufficiently small. The numerical example with the FAST simulator shows the effectiveness of the proposed distributed control method.
