The impact of the distribution network reconfiguration on active power losses: Selected issues of UPGRID project realization

The dynamic development of smart grids allows the use of remote controllable switches to change the configuration of the distribution network. The paper discusses the impact of the distribution system reconfiguration on active power losses, taking into account the typical daily load profiles. Based on modified IEEE 33-bus test distribution system the article presents the method of selection the appropriate sensitivity factor and the configuration of the MV network. The objective function is to minimize active power losses. The studies were performed using DIgSILENT Powerfactory software for two variants of the daily load curve and for different values of the sensitivity coefficient. The calculation results indicate, that adequate (optimal) configuration of MV distribution network, ensures reduction of active power losses.
