Abstract:

In order to achieve the medium and long-term goals of “carbon peaking” and “carbon neutrality”,as well as promote the development of new energy technologies,solve the imbalance of electricity demand,and reduce the pressure on the power grid peak load regulation.The hybrid energy storage technology has become a key to solving the problem.The hybrid energy storage system composed of the energy-type energy storage devices and the power-type energy storage devices is a system with both energy and power advantages,which greatly improves the power performance and economy of the system,which can not only smooth the fluctuation and randomness of the renewable energy generation,but also effectvely solve the problem of the insufficient power grid peak load regulation capacity.Therefore,the combined application of two or more energy storage technologies can effectively improve the grid-connected capability of the renewable energy and solve the above problems.The modeling,advantages and the simulation current state of different energy storage systems,and solutions and recommendations to address the growing burden on power grid are put forward.

Key words: hybrid energy storage, modeling of energy storage systems, fuel cell, lithium ion battery
