Implementation of dynamic energy storage technology and its integration with the power system represents another important step in the development of the energy sector. This article discusses the advancement of superconducting energy storage technologies and the possibilities of their use in power engineering as well as other branches of industry. It also presents the perspective of applications of superconducting energy storage type SMES (Superconducting Magnetic Energy Storage) both for commercial and industrial applications and their impact on power grid. The article analyzes the functions that systems can use with the use of a superconductor in the power system. The functionality of SMES systems has been analyzed in particular from the point of view of its use in railways.

The random nature of wind power along with active and reactive load changes results in both frequency and voltage fluctuations in a wind–diesel power system. In order to improve the dynamic performance by regulating the frequency as well as voltage of the system, an adaptive sliding mode control strategy is proposed on superconducting magnetic energy storage unit interfaced with a wind–diesel power system. Sliding mode control strategy developed with the superconducting magnetic energy storage unit achieves fast and effective exchange of real and reactive power via firing angle control of the converter. With the help of suitable switching surface design and use of adaptive control law, chattering elimination and controller robustness is achieved. This work is carried out in MATLAB/Simulink, and simulation results presented shows a positive impact of proposed scheme.

Unified Power Flow Controller (UPFC) is a Voltage sourced converter based Flexible A.C.Transmission  (FACTS) controller which has a capability of simultaneously or selectively controlling all the parameters affecting transmission of power.  With emphasis on harnessing renewable energy many energy storage technologies are being used. Superconducting magnetic energy storage (SMES) stores energy in magnetic form by means of a D.C. current circulating in a superconducting coil. To exchange power with SMES a power electronic interface is required. Feasibility of interfacing SMES to D.C. link of UPFC has been explored in this paper. A multimachine system with a long transmission line is compensated by UPFC-SMES .A DC-DC chopper modulates power of SMES so as to improve the transient stability of system. Complete simulation has been done using MATLAB/Simulink which shows improvement of first peak, damping of oscillations & improvement in critical clearing time.
