Means selection and capacity configuration of energy storage

In this paper, familiar means of energy storage are compared with respect to both performance and cost, on the basis of which some general rules are discussed on how to select proper energy storage means. Based on integrative analysis of capacity-fluctuation´s impact on system and customers, some technical requirements of energy storage capacity configuration are determined. Proper capacity proportion of energy storage corresponding to total power generation is discussed by considering both technical performance and economical factors. An optimal method on how to determine the proper capacity of energy storage is proposed and demonstrated by a simulation case. The motive to propose the rules and method in this paper is to arouse more attentions and in-deep study on manner selection and capacity configuration of energy storage.
