Abstract

Voltage stability has become an important issue because there are some blackout incidents have been happened that caused by voltage instability. The main problem of voltage instability is the failure working of reactive power demand as the load demand increases. In this project, the main objective is to investigate the voltage stability control in a power system. A designed micro grid system is modelled without controller to analyze the voltage stability. To maintain the voltage stability of system, Artificial Intelligence (AI) technique as a proposed method is developed with Fuzzy Logic (FL) technique. As a comparison, a micro grid system with Proportional Integral (PI) controller is modelled and compared the analysis results with Fuzzy Logic Controller (FLC). As result obtained, the voltage stability in a power system is investigated with artificial intelligence technique. According the results obtained, a PI controller is performed a better result in high load power while a fuzzy logic controller has a better performance in low load power. Thus, both controller can be used to control the voltage stability of the micro grid system.
