Optimum placement of Interline Power Flow Controller (IPFC) to simultaneously reduce losses, cost and improving the power system load ability using PESA_II algorithm

The use of FACTS devices is increasing due to the improvement of the transmission capacity of lines and the reduction of losses and costs related to the power system, and for this reason, new devices are used. One of these tools is the of interline power flow controller (IPFC), whose main task is to control the inter-line power of the transmission system, and it is one of the newest FACTS tools. In this article, the placement and regulation of the controllable parameters of IPFC has been discussed in an optimal way. The main goal of this optimal placement of IPFC in a multi-objective manner in the power network is to simultaneously reduce system losses, cost, and also improve system load taking into account the relevant constraints. In order to carry out placement studies, the selection algorithm based on beam forming or PESA_II has been used, and the placement process has been carried out on the IEEE 30-bus network. The results show that all indicators have improved so that compared to the case where IPFC is not present in the network, active power loss (%) is reduced by 59.43, load capacity (%) is increased by 32.08, reactive power loss ( 26.63% reduction and power plant fuel cost has decreased 59.01%.document.
