Abstract

Abstract: Energy cooperation between multi-island microgrids can improve overall economics. However, some island microgrids, especially in the pelagic ocean, do not have the engineering conditions for laying submarine cables. For such island microgrids, marine mobile energy storage systems, i.e., vessel-mounted container energy storage systems, can be used to achieve energy exchange. Nevertheless, it is debatable how to realize energy trading for island microgrids under this scenario. This paper first proposes a novel energy cooperation framework for multi-island microgrids based on marine mobile energy storage systems to realize energy sharing. Firstly, an energy transportation operator is defined to manage marine mobile energy storage systems and trade with island microgrids. Secondly, a bi-layer energy trading problem is modeled via the analytical target cascading method. The upper layer is energy trading between island microgrids and the energy transportation operator, and the lower layer assigns scheduling tasks to each marine mobile energy storage system. Furthermore, a benefit-sharing mechanism based on the asymmetric Nash bargaining model is designed. Especially, a nonlinear contribution mapping method with the exponential function is presented to determine the contributions of island microgrids. Finally, numerical simulations verify the effectiveness of the proposed energy cooperation framework. Highlights: Marine mobile energy storage systems are used to island microgrids interconnection. A novel energy cooperation framework for island microgrids is proposed. A bi-layer ATC-based energy trading model is presented to solve efficiently. A benefit-sharing mechanism based on the Nash bargaining theory is designed.
