The Comparative Analysis of Systems of Long-Term Electric Power Storage Intended for Sources of Back-Up and Emergency Power Supply, as Well as for Power Plants Using Renewable Energy Sources

摘要

This paper describes variants of using electric power accumulators of various types-lithium-ion and lead-acid storage batteries, flow-through redox storage batteries, and the hydrogen cycle-for the niche of back-up and emergency power supply sources designed for long periods of operation (8-72 h). The schematic diagrams are proposed, and, on the basis of data submitted by equipment manufacturers and designers, the comparative technical and economic analysis of these systems has been performed.
