Abstract In this paper, a smart inverter model for voltage regulation in distribution lines which has been paid attention as a feasible solution on voltage rise due to interconnection of large amount of distributed generations (DGs) is developed. Typical functions including Volt-Var and Volt-Watt control are implemented by using MATLAB/Simulink and inverter average model based on controllable 3-phase current source is utilized in the smart inverter model. Performance of the model implemented is verified by considering various conditions and it is confirmed that this model can effectively solve overvoltage problem at point of common coupling (PCC) in case of distribution system with large amount of DGs.
