Comparative analysis between SMES and BESS in application of VSC-HVDC system

High penetration of renewable energy resources which are more remote, uncertain and variable in grid is harming power system security Power industries are facing difficulties to transmit power from these resources to remote areas. For this HVDC transmission is preferable for long distance and an energy storage device is noble solution to mitigate power fluctuation problems by having the ability to instantaneously exchange the active and reactive power in the system. Superconducting magnetic energy storage (SMES) shows various superiority over other storage technologies with highest efficiency and its other applications in power systems. In this paper a comparative analysis has been made between battery energy storage system (BESS) and SMES in VSC-HVDC applications to shows that SMES is superior over BESS for performance enhancement in case of a.c./d.c. perturbations.
