A modified ANFIS controlled Unified Power Flow Controller for Power Quality Improvement in Transmission System

Nearly every component of the system, including the generators, the transmission and distribution lines, and the loads themselves, contributes either to the production of reactive power or to its consumption. The capacity of an interconnected power system to return to regular or stable functioning after being disrupted in some way is referred to as its stability. It is getting more difficult to maintain synchronism amongst the different components of the power system as linked systems continue to expand in size and spread out across huge geographical areas. In this paper, the capacity of the Custom Power Active Transformer that deliver UPFC services is investigated. These services include power flow management, reactive power compensation, voltage regulation, and the removal of harmonics. A 69kV transmission line American Electric Power system namely IEEE 14 test bus system is considered for dealing the power quality issues like reactive power compensation and harmonic elimination. A modified ANFIS (BA-ANFIS) controller is used to control the UPFC. All the simulations carried out in MATLAB/Simulink.
