Small Signal Stability Analysis of Wind Turbine Penetration in Sulselrabar Interconnection System

Abstract

This paper present and explain the analysis of power flow and small-signal stability of the electrical system in the islands of South Sulawesi, East and West (Sulselrabar) located in Indonesia. The research focused on the Eigen values analysis that used to investigate small-signal stability performance of the main electricity grid when the fault conditions with and without control equipment as well as the inclusion of wind turbines large scale on the system. Power Systems Analysis Toolbox (PSAT), which integrated in MATLAB is used to develop a network topology in Sulselrabar. This study allowed us to determine the optimal location of the placement of Power System Stabilizer (PSS) to dampen the oscillation. The simulation result shows the placement of PSS on two generators can add system stability and help the system to resume operation at the balance point. Time domain simulation methods are used to see the frequency response of the rotor speed.
