Stratified Configuration Of Electrochemical Energy Storage In Distribution Network

This paper has reviewed the study process and application situation of Electrochemical Energy Storage (EES), and has a comprehensive assessment by RAMS/LCC system from many aspects for Lithium-ion battery, Sodium-sulfur battery, lead-acid battery, Redox-flow battery totally five main EES technologies. It has explained the application and demands in distribution network (DN) of EES, and analyzed several problems to configure EES in current applied demonstration, so put forward a stratified and distributed energy storage configuration architecture which comprehensively considers EES function demands, technological performance and product's features. It also proposes the application trend of EES in future DN, offering reference for relevant implementation of engineering construction.
