AbstractCurrently, there is a rapid growth in the installation of photovoltaic solar systems in power distribution systems. The functionalities of smart inverters can bring benefits in the operational performance of the network. In this work, the influence of the smart inverters control functions: fixed power factor; Volt-VAr; and Volt-Watt, is evaluated in the voltage regulation of the network, assuming various operating scenarios. For this, power flows are simulated considering quasi-static time-series that incorporate the dynamic behavior of the distribution system. The simulations and analyzes are carried out in a real distribution feeder of an Ecuadorian utility. The results show that under simulated test conditions, the inverter’s Volt-VAr control presents better results in supporting voltage regulation.
