Research on Technology Readiness Assessment of Typical Energy Storage Technology for Power System

Currently, different forms of energy storage for the electric power system (ES-EPS) are developing rapidly, but they are lack of technology readiness assessment. In this paper, combined with the existing technology readiness assessment method, a technology readiness assessment system to the energy storage for the electric power system is proposed, and then applied to typical energy storage technology. Specifically, firstly, the conception of technology readiness and related assessment methods are introduced. Secondly, based on the commonly used 9-level Technology Readiness Level (TRL), combined with the development characteristics of typical ES-EPS, the description of technical maturity level suitable for ES-EPS is given. Thirdly, the milestone elements of typical ES-EPS are proved; Finally, by matching the milestone elements with the technology maturity level table of ES-EPS, the technology maturity level corresponding to typical ES-EPS are obtained, together with the bottlenecks encountered in the development of ES-EPS are presented.
