Smart grids and power system reliability

Abstract

Smart grids and the reliability of the power system issues are discussed in the paper. Smart Grids have emerged as a mean to increase the efficiency of energy systems around the world. Based on the analysis of Smart Grid implementation, liberalization of the electricity market and system reliability, it is concluded that Smart Grid has not improved the reliability of the power system The reliability can be improved only by constant investment in production and capital plants of the system, with optimal use of smart grids.. The paper presents the case study of disintegration of the power system under calm weather conditions, and case of low quality of power delivery where smart grids did not help enough.
