Optimal Placement and Sizing Sources of Distributed Generation Considering Information Uncertainty

Abstract

Distributed generation (DG) plays an important role in the development of modern systems of electric energy distribution and the formation of Smart Grid. The appearance of generating sources in the structure of electric networks can have a significant effect on the whole spectrum of technical and economic indicators of distribution systems. At the same time, in many cases, renewable energy sources are used as DG. Their peculiarity is the inability to accurately predict the output power. Thus, a such energy sources introduce some peculiar properties into the process of modeling of distribution network modes of operation, which is related to the need to take into account the uncertainty factor. In this regard, the paper deals with the justification of the power and operating modes of DG sources when they are integrated into certain nodes of distribution networks in order to minimize operational costs, considering information uncertainty.
