Cost-Benefit Estimation of the Smart Grid Development for the Russian Unified Power System

The paper is devoted to the issue of smart power system cost-benefit analysis. The innovative character of smart grids is defined and related obstacles for traditional cost-benefit assessment are revealed, primarily referred to external effects evaluation. Brief systematization of existing methods of smart grids assessment is provided and their weak points are defined. A new Smart Grid cost-benefit assessment approach is presented, basing on the elaborated comprehensive system of smart power system effects. The approach is tested for the system effects of smart power system implementation in the Russian Unified Energy System, quantitative results are presented
