Application of SSSC for Voltage Stability Improvement in the Nigerian 330 kV Transmission System using Particle Swarm Optimization Technique

“…In the real power generation system, the occurrence of voltage instability is usually caused by the imbalance of transmission capability of the power system network, increase in the generation plant reactive power, exceeding the voltage control limits, and inadequate monitoring of the voltage sensitivity as a result of load increase (Das & Panigrahi, 2020;Zhang, Fu, Diao, Sheng, & Jia, 2018). Therefore it can be seen that the voltage stability problems in the modern Nigerian power system network is an issue related to existing power system constraints and increase in voltage collapse, hence, the introduction of flexible alternative currents transmission system (FACTS) which has been studied and found to be essential in the improvement of the voltage stability by effective control of the active and reactive power (Li, et al, 2020 ), the authors utilized voltage collapse predictive point which was centered on the quadratic line voltage stability index (q-LVSI) and the machine earning auditory intelligent technique (AMI). The proposed model method was applied to the 30 bus network of the Nigerian 330 kV transmission network and the outcome of the model was validated with group method of data handline time series model (GMDHtime-series) which was a polynomial model utilized for the fitting of the artificial neural network model based on the inductive network learning and self-organization system.…”
