Energy Storage based stability control device has been proven very effective to improve power system stabilities by providing the unbalanced dynamic active and reactive power compensation of AC power systems. Detail of the analysis and a mathematic model of such kind of control device are given in this paper. Based on the developed model,extensive analysis including both the eigenvalue analysis and the time domain simulation is carried out to investigate the characteristic of such kind device. As examples two kinds of energy storage devices, a superconductive magnetic energy system (SMES) and a flywheel energy storage, are discussed.The SMES based stability control device is realized with superconductivity technology, power electronics and control theory. In order to promote the application of such kind of control device and to further investigate the characteristics ofthe controller, the capability of SMES to increase power system transient and small signal perturbation stabilities is analyzed. A prototype SMES is developed. The performance of the prototype is experimentally investigated in a laboratory environment. The flywheel energy based device call multi-functional flexible power compensation (FPC) in this paper is also introduced. Its characteristic is investigated by digital simulation. Very encouraging results are obtained.
