Resumo

The recent changes in distribution systems have challenged utilities to assess the unprecedented volume of photovoltaic (PV) generator connections, which can result in adverse technical impacts from voltage rise and conductor overload. Therefore, a fast and effective way to analyze a distribution system's capacity to host new PV generators is crucial for the utilities. Usually, the connection assessments are based on repetitive power flow and short-circuit calculations, and even though these analyses can be accurate, they require a steep increase in person-hours and processing time. A simpler way to identify the hosting capacity of distribution systems to the connection of new PV generators is the adoption of connection assessment tools that, if properly designed, allow utility engineers to evaluate quickly if a new PV generator can be connected or not. This work proposes a connection assessment tool based on a fast screening approach that allows utility engineers to graphically analyze if a rooftop PV can be connected to a distribution system without causing adverse impacts. Tests of the proposed method are performed in two real distribution systems, attesting to its efficiency. (AU)
