Research on hybrid energy storage planning of isolated integrated energy system based on EMD decomposition
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.
