Summary: Due to the predicted dynamic growth of renewable energy sources, the impact of their operation on the power system needs to be analyzed. The issue is not just about the operation, but also about the determinants of the development of such power sub-sector in the context of increasing the efficiency of electrical power distribution. Preliminary research in this field indicates positive experiences; additional dispersed sources reduce transmission losses. The paper presents analysis results on the actual network part including the level of these changes as a function of the power increase in new sources. A novel concept in the paper is the concept of hybrid renewable energy, consisting of a conventional solution supplemented with energy storage. The built-in device allows for even greater energy management – it offers the opportunity to implement a broader scale of DSM rules, which is the so-called Inverted DSM, which does not require dependence on the consumers of electricity when carrying out the load curve equalization. The final results of the analyses will be based on the distribution efficiency ratios for distribution networks using the proposed hybrid systems.
