On the Problem of Arrangement of Hybrid Energy Storage Systems

. Electric energy storage systems are widely used in electric transport, power engineering and order to provide autonomous supply load regulation of systems. One the ways increase technical economic efficiency devices is their hybridization, i. e. creation consisting blocks different types batteries. The special literature contains no systematic analysis qualitative quantitative effects hybridization corresponding methodological recommendations for choosing a scheme evaluating effectiveness hybridization. In present article, this issue considered from theoretical standpoint, given design serving solar or low-power wind farms. A brief overview data on cost buffering electricity with lithium-ion, lead-acid batteries supercapacitors made. method proposed determining necessity degree an device based simplest dependencies parameters notions coefficient synergetic effect internal introduced. quantitative-and-qualitative model presented. approach calculating recovery It shown that, general, adding supercapacitor unit lithium-ion does not lead reduction due high ratio At same time, feasibility using compensate pulse loads can be determined basis frequency spectrum graph unit. developed models approaches electrochemical specified operating conditions.
