Razvoj programskih rješenja za modeliranje i analizu naprednih distribucijskih mreža

With the continuous increase in the share of distributed energy resources, the task of the distribution system operator (DSO) is more demanding than before. The integration of new technologies makes it impossible to use traditional approaches in the planning and operation of distribution networks. Given the environmental and economic benefits of integrating distributed energy resources, it is crucial to develop methods that will enable the analysis of technical conditions in distribution networks with a high share of low-carbon technologies. This report presents two developed algorithms, the three-phase optimal power flow, and the singlephase and three-phase harmonic power flow algorithm. For both algorithms, mathematical models are presented, as well as a comparison of results with already developed and widely-used simulation tools. The functionality of the developed algorithms is shown in two examples in which the potential maximum production of photovoltaic panels in low-voltage networks is determined and the influence of distributed sources on harmonic interference in the network is analyzed.The European Commission through the European Regional Development Fund grant KK.01.2.1.02.0042 DING
