Abstract

Small-disturbance angle stability or low-frequency oscillation is one of the important stability in the power system. Although damper windings and power system stabilizer (PSS) have been proved to stabilize and improve small-disturbance angle stability. However, due to increasing demand in the recent years, adding redox flow batteries (RFB) as additional devices is crucial. This paper investigates, the utilization additional devices called RFB to enhance the small-disturbance angle stability in the power system. Furthermore, ant colony optimization (ACO) method is used to tune RFB parameter. To analyze the stability improvement on the power system, single machine infinite bus is used as a test system. Eigenvalue and time domain simulation is used to examine the behavior of the investigated system. From the simulation, it is found that by installing RFB in the system, the small-disturbance angle stability of power system is improved and ACO can be a solution of tune RFB parameter.

Abstract

One of methods that can be used to determine the stability of a power system if the fault occured is the equal area criterion method. The equal area criterion method (Equal Area Criterion, EAC) is an example of a direct method for predicting the stability and also the critical clearing time (Critical clearing time). However, to calculate the complex calculations required to determine the equivalent impedance of each condition system. In this study used several approaches to facilitate the calculation of the equivalent impedance. This method uses the equation of power losses. This method is equivalent impedance using modified with Ploss and Qloss for Determining Pmax. From the analysis, it can be concluded the use of this method is quite accurate in analyzing or calculating the transient stability of the generator system in South Sulawesi, with each loading condition, before, during and after short circuit. Generator being looked at is Bakaru, Pare, Suppa, Barru and Sengkang.
