A power system is a complex, nonlinear, and dynamic system, with its operating parameters continuously changing with time. High-voltage transmission power systems are frequently subject to transient instability problems due to the complexity of large load lines and faults, which results in power losses and higher voltage deviation. This problem can lead to catastrophic events such as cascading failure and/or widespread blackouts. Based on the collected data in 2021 GC from the EEP office, Ethiopia's high-voltage transmission power system in the North-West region is a victim of this problem. Du...
A power system is a complex, nonlinear, and dynamic system, with its operating parameters continuously changing with time. High-voltage transmission power systems are frequently subject to transient instability problems due to the complexity of large load lines and faults, which results in power losses and higher voltage deviation. This problem can lead to catastrophic events such as cascading failure and/or widespread blackouts. Based on the collected data in 2021 GC from the EEP office, Ethiopia's high-voltage transmission power system in the North-West region is a victim of this problem. Due to the growth in demand for electrical energy, the maximum capacity of the transmission lines should be increased to ensure a secure and uninterrupted power supply to consumers. This can be achieved by means of the installation of flexible AC transmission system (FACTS) devices. To address the problem, this research uses ANFIS-based UPFC for high-voltage transmission lines. Preference was given to this device for its fast-acting reactive power compensation on high-voltage transmission networks. The PSO algorithm was used to locate the optimal placement of the UPFC.
