Approach, allowing the use of data regarding an electric energy consumption for determination of typical values (peak, minimum, average) of electrical loads or their curves for separate consumers or group of consumers, is described in this article. The important factor of effective application of the developed algorithm is a presence of objective, reliable information about the typical load-curves of consumers, that is differentiated not only on technological principle, but also in according with the seasons of year and characteristic days of week. The offered algorithm allows one to take into account the actual uncertainty of the used limited statistical data in the process of the construction of typical load curves in an interval form, not only for consumers but for alternative generating sources, integrated in distribution networks as well. The set of algorithms, directed to the increase of adequacy of load modeling in the power supply systems with the sources of the distributed generation, is also considered in-the paper.
