The correct taking into consideration the uncertainty of the initial information is an important element in the process of decision of a wide range of problems of operational control and planning in the modern distribution systems. The actuality of the mentioned problem will not disappear in the course of the further formation of the integrated power systems. Inevitable development of information base in a certain measure will be compensated by the additional uncertainty, brought by active implementation of alternative energy sources. In this connection, the approach, allowing one to use in the optimal form the all available in power company’s direct and indirect information related to electrical loads, is offered in this article. The developed algorithms allow forming the generalized estimates of loads and certain characteristics of energy sources of the distributed generation on the basis of aggregation of the diverse retrospective data. To realize this problem the mathematical approach of the fuzzy sets theory is used.
