This book discusses three novel applications based on a Sub-Synchronous Series Controller that has a strong positive impact on power system. First novelty of the research presented is the introduction of a SSSC for the design & implementation of shared/robust control on the Gulf Co-operative Council grid.Second novelty is describing the operation of the SSSC device using three control limits based on the PI controller's three sets of new tuning parameters attained by incorporating a COOPER control optimization. These parameters will adjust the SSSC device compensation factor in both...
