Comparative study of Enhanced Power Flow Controller and TCSC

摘要

Flexible AC Transmission System (FACTS) controllers are based on technology which provides better control, reliability, system stability; power transfer capability for transmission network by using power electronics (PE) based switches. Their high capital cost and reliability problems have limited the use of FACTS controllers in smart grid systems. In recent times, a new approach of Distributed-FACTS (D-FACTS) was known as anew methodology to recognize cost-effective power flow control through multiple modules, small in size, fixed series impedance injections in power transmission network. These small D-FACTS controllers are distributed over whole transmission line as modules at every small short span of length which are mounted on the transmission line. D-FACTS controllers can dynamically and statically change the impedance of the connected transmission line to control the power flow. A new D-FACTS device Enhanced Power Flow Controller (EPFC), which is distributed version of Thyristor Controlled Series Compensator (TCSC) FACTS controller, has been analysed on MATLAB model and the results are compared with conventional TCSC controller. The comparative results are shown in the manuscriptafter MATLAB simulation which concludes that D-FACTS are more beneficial to use.
