Load shedding scheme for an interconnected hydro-thermal hybrid system with SMES

D. TYAGI, Ashwani KUMAR, Saurabh CHANANA

Frontiers in Energy 2012, Volume 6, Issue 3,   Pages 227-236 doi: 10.1007/s11708-012-0198-6

Abstract: The frequency of the power system varies based on the load pattern of the consumers.Further increase in the load will result in more frequency drop leading to the need of load shedding,The load shedding steps were obtained based on the rate of change of frequency with the increase in theload in both areas.The impact of superconducting magnetic energy storage (SMES) was obtained on load shedding scheme.
