Decentralized coordinated control of hybrid wind-thermal power system

Modern power system is a hybrid power system, which contains renewable power plants. In those power plants, wind farm has shown the world´s fastest rate of growth. The reported researches about decentralized coordinated control of power system are all based on synchronous generator (SG). It is not suitable that applying this decentralized-coordinated method to a hybrid power system for that the wind-generated energy capacity has been reached a considerable level. Combining correlative measurement modeling and multiple model predictive control, this paper proposes a decentralized coordinated multiple model predictive control (DCM-MPC) for a hybrid wind-thermal power (HWP) system. The transient problems of wind power integration are discussed subsequently. A simple, generic HWP system is used to illustrate the contributions. The results show that the proposed DCM-MPC not only provides an accurate tracking performance, but also improves transient stability of the HWP.
