“…Superconducting Magnetic Energy Storage (SMES), Battery Energy Storage System (BESS), Flywheel Energy Storage (FES), and Pumped Storage Hydro Power Station (PSHPS) are commonly used ESS in power system stability control [1][2][3]. To investigate and validate the capability of those ESS in one of the important applications of stability control -to suppress power system oscillations, various tools and techniques have been used, such as the modal analysis based on linearized models for SMES [4][5][6][7][8], modeling power electronics into power systems for BESS [9][10][11], simulation and laboratory experiment for FES [12] as well as application of advanced control theory for BESS [13,14]. Research results obtained so far indicate that ESS control can significantly enhance power system stability by damping system oscillations effectively, which has been confirmed by field applications of BESS and PSHPS reported in [15] and [16] respectively.…”

a b s t r a c tAn Energy Storage System (ESS) installed in a power system can effectively damp power system oscillations through controlling exchange of either active or reactive power between the ESS and power system. This paper investigates the robustness of damping control implemented by the ESS to the variations of power system operating conditions. It proposes a new analytical method based on the well-known equal-area criterion and small-signal stability analysis. By using the proposed method, it is concluded in the paper that damping control implemented by the ESS through controlling its active power exchange with the power system is robust to the changes of power system operating conditions. While if the ESS damping control is realized by controlling its reactive power exchange with the power system, effectiveness of damping control changes with variations of power system operating condition. In the paper, an example of power system installed with a battery ESS (BESS) is presented. Simulation results confirm the analytical conclusions made in the paper about the robustness of ESS damping control. Laboratory experiment of a physical power system installed with a 35 kJ/7 kW Superconducting Magnetic Energy Storage (SMES) was carried out to evaluate theoretical study. Results are given in the paper, which demonstrate that effectiveness of SMES damping control realized through regulating active power is robust to changes of load conditions of the physical power system.

“…The forced-commutated convertor which is based on GTO thyristors, enables the SMES system to generate or absorb active and reactive powers in four-quadrants. An SMES system with these functions can be considered as a controllable current source, with amplitude and phase controlled by active and reactive power regulators (Simo and Kamwa, 1995).

SUMMARYThis paper presents a new scheme for smoothing out the voltage and frequency fluctuations simultaneously in a hybrid wind-diesel system using a super conducting magnetic energy storage (SMES) unit. The SMES unit located at induction generators' terminal bus, uses local measurements for exchanging real and reactive powers simultaneously in four quadrants. Complete model of the hybrid wind-diesel-SMES system is developed and is used for eigenvalue analysis and design of controllers. Computer simulation results illustrate the positive impact of the SMES unit on the quality of the supply and furthermore some modifications of the controller design are proposed.1998 John Wiley & Sons, Ltd.

Due to the randomness and uncertainty of wind power, voltage fluctuation in large-scale wind power system should not be ignored. The stepped controllable shunt reactor (SCSR) is an effective method to regulate voltage within its limits in this paper. The physical structure and working principle of SCSR are analyzed in detail. Voltage control method of SCSR is proposed, which is based on the bus voltage fluctuation of high voltage side in transformer substation. Calculating method for each required capacity is given. Combined with actual engineering project, the stepped controllable shunt reactor (SCSR) is demonstrated to be applicative and effective. Its capacity can adjust automatically according to operating characteristics of wind power. It can maintain voltage of the controlled bus in modest bounds. It has effect on the safe and good quality operation in large-scale wind power system.
