Supercapacitors Energy Storage System for Power Quality Improvement: An Overview
ABSTRACT
The paper [7] shows that Power quality problem causes a misoperation
or failure of end user equipments. Distribution network, sensitive in-
dustrial loads and critical commercial operations suffer from outages
and service interruptions which can cost financial losses to both utility
and consumers. In India the use of electronic loads is increasing very
fast and the gap between demand and the supply have made the reli-
ability and power quality a critical issue. Further there is continuous
thrust on optimal utilization of the non-conventional energy sources
along with the central power station. In this paper a critical review
have been presented chronologically various work to improve quality
of power with the help of energy storage device i.e. Supercapacitors
energy storage systems for ASD, elevators, UPS, and power distribu-
tion system, ride through capability, real power injection and reactive
power injection for stabilization of the system.
