A Novel Modified Lightning Attachment Procedure Optimization Technique for Optimal Allocation of the FACTS Devices in Power Systems

The Flexible AC Transmission Systems (FACTS) are the static power electronic devices that installed and used in transmission networks to enhance capability of transferring for providing controllability stability. However, optimization site size these is a crucial task due their high capital cost practical capabilities. In this paper, optimal reactive dispatch (ORPD) embedded with two effective controllers including Static VAR Compensator (SVC) Thyristor Control Series Capacitor (TCSC) solved using Modified Lightning Attachment Procedure Optimizer (MLAPO). searching basic LAPO enhanced stagnation avoided by application levy flight distribution spiral orientation motion. reducing losses, voltage deviations, operating cost. MLAPO examined tested on modified IEEE30 IEEE57 bus-standards considering SVC TCSC. effectiveness further analyzed compared outcomes well-known techniques namely LAPO, PSO, ALO, EO, MPA, WOA SCA without FACTS devices.
