Optimal Design and Control of SSSCs for TLs Considering Technical and Economic Indices Using GA and SAMPE-JAYA Algorithms

Improving transmission lines (TL) steady-state stability limit can be achieved by Static Synchronous Series Compensators (SSSC) that work as a converter-based compensator. The modification of the SSSC function to inject both active and reactive power into TL improves its performance according different indices. improvement indices include reduction losses, enhancement dynamic margin voltage profile along TL. economic index is considered vital factor in design devices installed TLs. This paper proposes an objective control considering various technical economical formulation requires flow analysis compensated line under loading conditions compensation levels. proposed multi-objective includes span, cost device. Genetic Algorithm (GA) Self-adaptive Multi-population Elitist Jaya (SAMPE-JAYA) are optimization techniques obtain minimized value function. installation two leads indexes. applied for tie-line (400kV, 400km) connects between networks.
