Technical Structure and Operation Principle of Mechanical Elastic Energy Storage System

摘要

With the increasing proportion of renewable energy in the power system, energy storage technology is gradually developed and updated. The mechanical elastic energy storage is a new physical energy storage technology, and its energy storage form is elastic potential energy. Compared with other physical energy storage forms, this kind of energy storage system has its own characteristics and advantages. Firstly, the structure and working principle of mechanical elastic energy storage system are introduced in this paper. Secondly, the modular push-pull mechanical assembly technology of series linked energy storage tank group is designed, which greatly simplifies the installation process of energy storage tank group. And the mathematical model of the energy storage tank group is established, which provides the design criteria for the operation power/energy storage capacity of the energy storage system. Finally, the feasibility of the proposed energy storage technology is verified by experiments.
