Abstract :

Low Frequency Oscillations (LFO) occur in power system when the imbalance conditions take place during the system operations due to any cause it will give impact on the sensitive system parameters.LFO damping is important in electrical power system design and operation. Due to unexpected large power consumption in industries and other sectors, to make smoother operation between generation and expected demand, various damping techniques has been developed with time. For the reliable operation of a small power system various controllers are used for same purpose. So many methods are improved with time in order to obtain better results. In the recent past Power System Stabilizer (PSS) was used to damp LFO and also the FACTs device Unified Power Flow Controller (UPFC), can control power flow and may be used to damp LFO instead of PSS. UPFC damps LFO through direct control of voltage and power through various methods. Keywords- Low Frequency Oscillations (LFO), Power system stabilizer (PSS), Unified Power Flow Controller (UPFC), neuro-fuzzy controller (ANFIS)
