Optimization of Power System and Stability Analysis Using Facts Controller

Abstract

Power supply regulates the competence of the consumer appliances, without real power, an newlineelectrical appliance is not able to perform up to its optimum capabilities. The performance of newlinean electrical system is strongly connected to the characteristics of load connected at the newlineconsumer side. The increased use of non-linear loads in the distribution system has resulted in newlinedeterioration of the power quality of the electric system. The power quality has to ensure the newlinecontinuity of supply in distribution networks, should aim to compensate consumers in the event newlineof long-term interruptions and to ensure uninterrupted power supply at adequate voltage level. newlineAlthough the generation of electrical power in almost every country is consistent, but there is a newlinelack of reliability at the distribution end, i.e. problem lies regarding the quality of supply due to newlinevariety of loads connected at the consumer end. There is a large increase in usage of non-linear newlineloads like electronic equipment, power electronic devices, Programmable Logic Controllers newline(PLC), energy efficient lighting system, Uninterrupted Power Supply (UPS) and inverters, etc. newlineThese non-linear loads bring distortions in voltage and current waveforms, introduce harmonics, newlineaffect other consumers in the vicinity and result in various power quality problems. newline
