Dynamic Matrix Control of Load Frequency Control for Doubly Fed Induction Generator Wind Energy Grid Connected

This paper presents Dynamic Matrix Control (DMC)-based strategies for the wind turbine- system. In order to the uncontrollable nature of the wind energy, the output power of the wind energy conversion systems (WECS) is also uncontrollable. This uncontrollability makes the WECS unable to respond to the load frequency variation when a system disturbance occurs. The instability of such a power system leads to the system failure. In this article, a model DMC is used for supporting load frequency control (LFC) in a doubly fed induction generator (DFIG)-based WECS under the variation of wind speed. It is illustrated that DMC can accept more feedback signals than any other conventional controllers, such as a proportional integral-derivate (PID), which makes it superior. simulation results illustrate that DMC gives stable response and faster to LFC than PID. The effectiveness of the methods is verified by time domain simulations.
