Abstract
Due to the fact that the distributed energy storage(DES) application scenarios are diverse and the potential of energy storage can not be fully utilized under the established strategy
based on the relationship between the sequence characteristics of the operating state of DES
a strategy for DES based on panoramic theory is proposed. First
the complementarity between decentralized energy storage in different application scenarios was taken into consideration
so that a complementary model of energy storage system response capacity was established; moreover
corresponding parameters of the panoramic theory were defined
and the distributed energy storage was grouped and aggregated using the energy function of the panoramic theory. Based on the determination of decentralized household energy storage aggregation
a decentralized energy storage transfer cost optimization model was established
and the results of energy storage transfer cost before and after polymerization were compared and analyzed. The case analysis shows that the proposed energy storage aggregation management method is feasible and economical
and provides a new idea for the operation of multiple energy storage aggregation.
