Analysing the Effect of Unified Power Flow Controller on Power System Performance
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 11
Abstract
The objective of the planning and operation of an electric power system is to satisfy the system load and energy requirement as economically as possible. Therefore, the system planner has to consider a variety of options, including Flexible AC Transmission Systems (FACTS) controllers, and they have to make decisions not only based on technical and cost considerations, but also on return of investment. FACTS controllers are characterized by their ability to have control algorithms structured to achieve multiple objectives in a transmission system. For this, an Optimal Power Flow (OPF) algorithm is considered to find a steady state operation point which minimizes generation cost, network loss etc. or maximizes social welfare or system utilization etc. while maintaining an acceptable system performance in terms of limits on generators’ active and reactive powers, line flow limits, maximum output of various compensating devices etc. In this paper, the complete mathematical model for one of the advanced FACTS controller i.e. unified power flow controller (UPFC) is developed and the effect of this device on system parameters is analyzed on standard test systems with supporting numerical and graphical results.
