SUMMARY:

In search of a low-carbon economy, investments in renewable energy generation technologies in place of fossil fuels have been increasingly high. Among renewable energy technologies, photovoltaic systems have had the highest net growth in the world, due to the reduction in their price in recent years (IRENA, 2020) and government policies, incentives and regulations (IEA, 2019). This growth, especially in rural and end-of-line areas, in times of high power generation and low demand, has resulted in the increase of the electricity grid voltage. In this context, this work aims to show a way to maintain the voltage of the network within the regulated limits, so as to allow the amount of photovoltaic distributed generation systems to keep increasing. For this, a Case Study was carried out, in which the Volt-VAr control method was applied in a photovoltaic inverter that presented overvoltage failures. The  definition of the Volt-VAr curve parameters took into account the following Brazilian regulations: NBR 16149 and Module 8 of the Prodist.
