Abstract
The problems of mode regulation of distribution networks in Ukraine are investigated in this paper. Authors propose to regulate the modes of distribution networks by the means of convertors of renewable energy sources (solar power plants etc.) connected to this networks according to the Smart Grid concept. The analysis of multicriteria mode optimization results of the distribution network was performed and the most perspective criterion were selected according to the features of structure and functioning of distribution networks in Ukraine. The target function of multicriteria optimization by the criteria of minimization of reactive power on the main section of the line and minimization of standard voltage deviations from the nominal value is formalized by the authors. To calculate the optimal value for the target function, the Multivariable extremum seeking control method was chosen, this method was improved by adding additional filters of individual frequency channels. An example of calculations is given in the paper; it illustrates the efficiency of the proposed method of modes regulating of the distribution networks. References 24, figures 3, tables 2.Keywords
