VOLTAGE AND REACTIVE POWER REGULATION IN DISTRIBUTION NETWORKS BY THE MEANS OF DISTRIBUTED RENEWABLE ENERGY SOURCES

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