  This paper explores the feasibility of social cooperation between prosumers
within an energy network in establishing their sustainable participation in
peer-to-peer (P2P) energy trading. In particular, a canonical coalition game
(CCG) is utilized to propose a P2P energy trading scheme, in which a set of
participating prosumers form a coalition group to trade their energy, if there
is any, with one another. By exploring the concept of the core of the designed
CCG framework, the mid-market rate is utilized as a pricing mechanism of the
proposed P2P trading to confirm the stability of the coalition as well as to
guarantee the benefit to the prosumers for forming the social coalition. The
paper further introduces the motivational psychology models that are relevant
to the proposed P2P scheme and it is shown that the outcomes of proposed P2P
energy trading scheme satisfy the discussed models. Consequently, it is proven
that the proposed scheme is consumer-centric that has the potential to
corroborate sustainable prosumers participation in P2P energy trading. Finally,
some numerical examples are provided to demonstrate the beneficial properties
of the proposed scheme.
