Transient Stability Analysis of Nine Bus Power System Network

Abstract

Modern energy systems are complex due to the highly interconnected networks of thousands of buses and production stations. Due to economic and environmental constraints on the installation of new generators and increasing load demand, transmission on existing lines increases. After that, the frequency fluctuates suddenly. Then, black-out occurs in the whole power system. This paper has been focused on voltage and frequency stability analysis. CYME PSAF software has been implemented as a real virtual laboratory for load flow and stability analysis. The Newton-Raphson method is a fast computational application. which is used in PSAF. The simulated data obtained from PISF is fully consistent with the real-time data. After simulation, it helps to reduce line loss, frequency loss, and mismatch, various countermeasures. A reasonable reduction in line loss and mismatch, therefore, represents a performance gain.
