With the large-scale development of integrated energy microgrids
microgrid cluster cooperative operation has gradually become an important way to improve the security and stability of the power system. As the regulation means for flexible operation of microgrids
integrated demand response can guide the active adjustment of multiple loads through price signals
and shared energy storage can realize inter-temporal energy balance through energy shifting
which provides important support for the cooperative operation of microgrids. In order to improve the economy of microgrid cluster cooperative operation and enhance the satisfaction of each participant
this paper constructs an asymmetric Nash bargaining model of a microgrid cluster with shared energy storage taking into account the integrated demand response. Firstly
the optimization models of microgrids and shared energy storage with integrated demand response are constructed with the optimization objective of minimizing the economic cost of each microgrid and shared energy storage
respectively. Secondly
an asymmetric Nash bargaining model based on the difference in the size of the energy contribution of each participant is proposed and decomposed into a cost minimization subproblem of the microgrid cluster and a trading tariff bargaining subproblem. Finally
a microgrid cluster is taken as an example for case analysis
and the results show that the constructed operation optimization model can effectively improve the operation benefits of the collective as well as the participant
and the cooperation benefits are fairly distributed based on the energy contribution size of each participant.
