Abstract

Nigeria, a country of over 200 million people, has witnessed high demand in power consumption in recent times. Consequently, power transmission lines have to transfer power at their maximum transmission limits. Stable and reliable operation of such transmission system can be achieved by monitoring the line stresses and predicting the effect of outages through contingency assessment. In this paper, a method of placement of interline power flow controller (IPFC) based on the probability of severity has been proposed. Composite Severity Index (CSI) of Fast Voltage Stability Index and Line Utilization Factor was used for the contingency ranking of lines for the placement of IPFC. IPFC is placed on the line with highest probability of severity during the event of different outages. Thereafter, cuckoo search algorithm was used to optimize the size of the IPFC. The method was applied to the Nigeria 330KV 31 bus system data. For this system, the overall CSI, active and reactive power losses were predicted to reduce by 2.22%, 15.35% and 28.11% respectively. The results show that optimal placement of IPFC effectively reduces line congestion and improves voltage stability. It also reduces the active and reactive power losses of the system and thereby reducing the risk of network collapse.
