Currently, new energy storage has become necessary supporting of constructing new power system, and reasonable energy storage policies and market mechanisms will have a profound impact on the healthy development of new energy storage. Therefore,it’s necessary to learn from advanced experience of countries with better energy storage development. Firstly, research on the planning and development status of new energy and new energy storage in Germany is carried out, and internal factors of the growth of new energy storage are analyzed from the aspects of economy, policy incentives and subsidy policies, and the mechanism of German energy storage’s participation in power market and main income model are further studied. Then, the development status, market mechanism and invocation mode of Jiangsu new energy storage planning are analyzed. Lastly, differences of energy storage development between Jiangsu and Germany are compared, and relevant experience of new energy storage development for Jiangsu power grid is summarized.
