Voltage Regulation in Distribution Networks Using Fuzzy Logic Algorithms

This paper proposes an automatic control system based on fuzzy logic to stabilize voltage levels in distribution networks. The system monitors the voltage of a power transformer under load conditions and regulates it by connecting or disconnecting static capacitor banks according to the consumerside voltage level and significantly reduces the number of OLTC tap changes. A mathematical model of the distribution network was developed in the MATLAB/Simulink environment and simulated using a fuzzy logic algorithm. The simulation results demonstrate that the proposed system responds adaptively to voltage fluctuations and effectively improves power quality and network reliability.
