Potential of Technical Losses Reduction in Low Voltage Feeder Using Small Photovoltaics

Efficiency of electricity systems is currently a high priority for the society. Our article focuses on the area of low voltage distribution system, where we focus more deeply on the possibilities of reducing technical losses. To achieve this goal, many traditional methods are known which require modification and intervention in the distribution system. Our concept is based on the possibility of reducing active losses using small photovoltaic systems installed at low voltage customers. For this purpose, a low voltage feeder model of the corresponding structure was created in this work. Using this model, a case study based on real data (solar irradiation data and typical daily diagrams of low voltage customers) was performed. The results of the simulations show considerable potential for reducing technical losses using the described concept.
