Abstract

The adoption of mini and micro distributed generation (MMDG) systems, particularly those based on photovoltaic solar energy, has grown significantly, supported by regulatory incentives. However, this expansion presents substantial challenges to the electricity distribution network, including feeder overloads, the risk of overvoltages, and a deterioration in power quality. These issues can negatively impact system stability and may result in penalties for utilities. Understanding the impacts of MMDG on the Brazilian electrical system is essential for developing solutions that ensure a stable and high-quality power supply, while also facilitating a more sustainable and efficient energy transition. In this context, this paper proposes a methodology for evaluating MMDG in medium-voltage distribution systems, taking into account technical aspects and recommending corrective actions where necessaryFinally, a qualitative analysis approach is proposed to assess the current impact of distributed generation on the medium-voltage electricity distribution network.
