Abstract :
Voltage flicker, a phenomenon of annoying light intensity fluctuation, caused by rapid change in industrial and domestic load such as electric arc furnaces (EAF), rolling mills, welding equipments and pumps operating periodically has been a major concern for supply utilities, electricity regulatory agencies and costumers. SVC´s and STATCOM have been able to solve the voltage flicker problems by rapidly controlling the reactive power. But, control of active power along with reactive power control helps to mitigate the voltage flicker problem more effectively. In this paper, voltage flicker mitigation of EAF with STATCOM along with energy storage system (ESS) is presented and performance results of the system using the PSCAD/EMTDC software are analyzed.
