A Novel Energy Sharing Framework for a Residential Community

The local energy sharing in a residential community has becoming a research hotspot in the area of distribution system. Designing a transparent energy sharing price scheme, ensuring users who participate in the energy sharing to gain benefits, and distributing the cost savings fairly are three key factors for establishing the local energy trading market. In this paper, we propose a novel energy sharing framework among residential users (RUs) with considering the demand response. First, an individual cost optimization is solved to find the potential buyers and sellers in every time slot, and further to calculate the energy sharing price. Then, an energy sharing problem is formulated, in which the interest of each RU is guaranteed by an incentive constraint. Finally, a redistribution problem is proposed to attack the problem of multiple energy sharing schedules and to recalculate the payoffs. The results show that the RUs can gain benefits via energy sharing and it is necessary to carry out the redistribution problem.
