SFO Based Economic Load Dispatch with FACTS Devices for DC Link Placement Problem

This Paper Presents a SFO based Economic Load Dispatch with FACTS devices for DC link Placement Problem. While most of the existing DC links are designed for point to point transmission, the multi-terminal DC system operation has become a reality and its usage is expected to increase in the future with a view of making the operation more flexible, secure and economical. The realization of multi-terminal DC systems cannot be done at once but can be executed by replacing the existing AC transmission lines with DC links over a period of time. The other development in power electronics pioneered FACTS devices that make the operation of the power system more flexible, secure and stable and have become popular in the recent years. The FACTS placement problem is another important optimization problem in power systems. New solution strategies involving FO have been suggested for the developed OPF with DC link and FACTS placement problem with a view of obtaining the global best solution in this paper. It presents simulation results of IEEE57 bus test systems with a view of demonstrating the effectiveness of the developed strategies.
