Following the unprecedented generation of renewable energy

Energy Storage Systems (ESSs) have become essential for facilitating renewable consumption and maintaining reliability in energy networks. However

providing an individual ESS to a single customer is still a luxury. Thus

this paper aims to investigate whether the Shared-ESS can assist energy savings for multiple users through Peer-to-Peer (P2P) trading. Moreover

with the increasing number of market participants in the integrated energy system (IES)

a benefit allocation scheme is necessary

ensuring reasonable benefits for every user in the network. Using the multiplayer cooperative game model

the nucleolus and the Shapley value methods are adopted to evaluate the benefit allocation between multiple users. Numerical analyses based on multiple micro-energy grids are performed

so as to assess the performance of the Shared-ESS and the proposed benefit allocation scheme. The results show that the micro-energy grid cluster can save as much as 38.15% of the total energy cost with Shared-ESS being equipped. The following conclusions can be drawn: the Shared-ESS can significantly reduce the operating costs of the micro-energy grid operator

promote the consumption of renewable energy

and play the role of peak-shaving and valley-filling during different energy usage periods. In addition

it is reflected that the multiplayer cooperative game model is effective in revealing the interaction between the micro-energy grids

which makes the distribution results more reasonable.
