Abstract

As a system that relies on internal energy to meet users' needs

island integrated energy system can guarantee continuous operation through energy storage technology. A configuration method for hybrid energy storage system composed of supercapacitor-battery-compressed air energy storage is put forward

on the basis of empirical mode decomposition(EMD). By using the EMD

the hybrid energy storage system power obtained by active energy storage strategy is processed

and the modal components obtained by EMD decomposition are reconstructed to determine the energy storage power allocation. Moreover

the power and capacity planning is conducted

and the optimal optimization scheme of hybrid energy storage system is determined by taking the whole life cycle cost of the hybrid energy storage as the optimization objective. Finally

the effectiveness and economy of the above planning method are verified by a specific example. The research can provide some technical reference for the planning and operation of isolated integrated energy systems.
