Technical Losses Assessment in Medium Voltage Feeders in the Presence of Distributed Generation

The integration of photovoltaic generation (PV) is the subject of study of the distribution companies, universities and research centers around the world, since there is a goal to measure the impact of the presence of this type of generation in distribution systems. In this work, the technical losses (or ohmic losses) in medium voltage (MV) feeders were evaluated considering the insertion of the photovoltaic generation. In general, it is verified that the insertion of this generation is associated to the reduction of losses in the feeders, since there is an intuitive idea of reducing its load. However, through several simulations in the Simulight software [1], this work describes situations in which the ohmic losses increase, also evaluating other relevant factors that influence this issue.
