Abstract:V sodobnih sistemih vodenja distribucijskih omrežij je ena izmed glavnih funkcij izračun pretokov energije. V tem magistrskem delu je izračun pretokov energije po eni izmed obstoječih metod uporabljen v kombinaciji z optimizacijskim algoritmom na realnem primeru distribucijskega omrežja Zgornje Savinjske doline, natančneje na daljnovodih Rastke in Logarska dolina. Ovrednoten je vpliv električne energije proizvedene iz razpršenih virov na obravnavano omrežje. S postopkom optimizacije so določene referenčne vrednosti za generacijo delovne in jalove moči razpršenih virov, ki so priključeni na nizkonapetostni strani transformatorskih postaj. Pri tem je analiziran vpliv generacije delovne in jalove moči na profil napetosti ter na izgube v obravnavanem srednjenapetostnem omrežju. Preverjena je robustnost in uporabnost predlaganega algoritma za različna obratovalna stanja.

Title:Analysis of the impact of distributed power generation on distribution network in upper Savinjska dolina
Abstract:The load flow calculation is one of the main functionalities incorporated in modern distribution network management systems. In this master thesis, an already known load flow calculation method, combined with an optimization procedure, is applied and tested in the case of real distribution network in Zgornja Savinska dolina (upper part of valley Savinjska dolina), more precisely on distribution lines Rastke and Logarska dolina. The impact of electrical energy produced in distributed generation units on discussed distribution network is evaluated. The optimization procedure is applied to determine the reference values for active and reactive power generation in distributed generation units connected to the low voltage side of distribution transformers, where the impact of generated active and reactive power on voltage profile and distribution network losses in medium voltage network is analyzed. The robustness and usefulness of the proposed algorithm regarding its suitability to be used in different operating conditions is checked.
Keywords:distribution network, distributed generation, load flow, optimization, voltage profile, losses
