Uticaj solarnih panela na gubitke u niskonaponskoj mreži

Abstract

The largest part of technical losses of electricity in electricity distribution are technical losses in low-voltage lines. Technical losses of electricity are losses that occur in the distribution of electricity from transformers to consumers in electrical distribution equipment. Commercial losses include unauthorized use of electricity and losses due to errors in measuring equipment. The main source of technical losses of electricity is caused by the flow of electric current through conductors. Solar panels installed by consumers can affect the reduction of losses by reducing the flow of electric current, i.e. of electricity through low-voltage lines. The presentation of the assumed daily diagram of the symmetrical load of the lowvoltage line is given with the calculation of losses per hour with and without the influence of solar panels. Solar panels effects are also shown in the daily diagram, as well as the voltage values at the end of the low-voltage line. In the calculation, an equivalent line with half the length and full hourly load is used for the lowvoltage line.
