Static Synchronous Series Compensator (SSSC) is a series compensating Flexible AC Transmission System (FACTS) controller for maintaining to the power flow control on a transmission line by injecting a voltage in quadrature with the line current and in series mode with the transmission line. In this work, an Adaptive Network-based Fuzzy Inference System controller (ANFISC) has been proposed for controlling of the SSSC-based damping system and applied in a Single Machine Infinite Bus (SMIB) power

For implementation of the learning process of this controller, we use from one approach of the learning ability that named as Forward Signal and Backward Error Back-Propagation (FSBEBP) method for improving of the system efficiency. This artificial intelligence-based control model leads to a controller with adaptive structure and improved correctness of the system, and finally cause to enhancing to the high damping ability and dynamic performance. System implementation is easy and requires 49 fuzzy rules for inference engine of the system. As compared with the other complex neuro-fuzzy systems, this controller has medium number of the fuzzy rules and low number of the layers, but it has high accuracy. In order to demonstrate of the proposed controller ability, it is simulated and its output compared with that of the classic Lead-Lag-based Controller (LLC) and PI controller.
