Optimal Location of Ipfc in Nigeria 330 KV Integrated Power Network Using Ga Technique

摘要

The Nigeria 330 KV integrated power system currently consist of the existing network, National Independent Power Projects (NIPP), and the Independent Power Producers (IPP). This network consist of Seventeen generating stations, Sixty four Transmission lines and Fifty two buses. Loss reduction and bus Voltage improvement control mechanism is still based on conventional devices (synchronous generators/condensers, tap changers, reactors and inductors) and building more generating stations and transmission lines as an alternative to meet the ever increasing power demand. This work modeled and analyzed the application of Interline Power Flow Controller (IPFC),which is a modern control Flexible Alternating Current Transmission System (FACTS)device on the network using Genetic Algorithm (GA) for its optimal placement and an option for power improvement. The result obtained showed improvement of weak bus voltages and loss reduction with and without IPFC devices on incorporation in the network. It is recommended that FACTS devices be incorporated into the power network for improved efficiency and not necessarily building more stations and transmission lines, as this is the current practice in Nigeria. This should be an integral part of the planning process for both the existing, NIPP and IPP in the country so as to meet the vision 2020 goal.
