This paper analyzes the impact of injecting distributed generation (DG) into feeder 0602SR0T04 in the city of Latacunga, Ecuador. The central objective of the study is to evaluate the effects produced by the strategic insertion of photovoltaic systems and how these influence distribution network variables. The methodology begins with the collection of technical data from elements connected to the network and georeferenced data, provided by the Provincial Electric Company of Cotopaxi (ELEPCO S.A.); subsequently, these were processed using data filters to build a simulation of the electrical network of said feeder in OpenDSS software. Once the simulation was built, solar irradiation profiles obtained online from NASA's POWER website were incorporated to represent the actual radiation of the area. The electrical model allowed the simulation of distributed generation penetration scenarios with stepped percentages (0, 25, 50, 75, and 100 percent), randomly selecting users with different average consumption values. The operational benefits in networks with distributed generation associated with energy injection at low voltage levels were identified. The results show a favorable impact on voltage profiles, current reduction, and loss reduction, which increase their effect as the percentage of DG increases. It is concluded that, if the simulated network were implemented, it would comply with the IEEE 1547-2018 standard if DG is injected at 100%. The electrical network simulation and original data are available in the supplementary data.
