Reactive power compensation is one of the leading ways to improve the power transmission efficiency. Currently, there is a problem of increasing the calculations accuracy for compensating devices selection and their application feasibility. The development of smart grids creates an information base that enables refined solution of such problems. We examine one of the ways to increase the accuracy in this work – it is the consideration of temperature dependence of the network resistance elements. In this case, we specify as the optimal values of power compensation devices, as payback periods. Moreover, the clarification for payback period could exceed 100%. We can apply a similar approach to other measures to reduce energy losses, and it opens up an additional field of research. We can use the results obtained in this study both as for power industrial systems, as for urban and rural distribution networks.

W niniejszej pracy rozpatrzono jeden ze sposobów zwiększenia precyzji kompensacji mocy – post temperaturowe zależności oporów elementów sieci. Określone optymalne wartości mocy urządzeń kompensacyjnych na podstawie okresu zwrotu. Podobne podejście można zastosować również do innych metod w celu zmniejszenia strat energii. Wyniki uzyskane w tej pracy, mogą być stosowane w systemach zasilania zakładów przemysłowych, a także w miejskich i wiejskich sieciach rozdzielczych.
