Dual Optimal Strategy with Receding Horizon Control of Wind Farm to Provide the Fast Frequency Response

In recent years, the overall inertia has decreased due to the increased penetration of wind turbines to power systems, and thus the risk of a system accident is exposed. Therefore, this paper proposes a dual optimal strategy with receding horizon control to provide the fast frequency response to the power system. A standard form of quadratic programming (QP) is applied to dual control strategies that obtain the total kinetic energy of wind farm and dispatching to each individual wind turbine. By utilizing the total kinetic energy of a wind farm with multiple wind turbines, it is possible to mitigate the secondary frequency reduction by operating the wind farm as a single generator, as opposed to regulating each wind turbine individually. The effectiveness of the proposed method is demonstrated in simulation model with IEEE 16 bus system using MATLAB/SIMUINK.
