To solve the problem of energy trading in the power market of multi-microgrid systems in the distribution network side
this paper proposes an optimization method for energy trading in multi-microgrid systems based on Stackelberg game. Firstly
the energy storage output and transaction status of the microgrid in the game stage are determined by single microgrid optimization strategy. Secondly
the optimization results of microgrid operation scheduling are interacted with the distribution system operator (DSO)
and a Stackelberg game model is established to engage in the game with internal electricity prices and dispatchable energy as the strategy. The optimization operation objective of the proposed method is to reduce the operation cost of microgrid
improve the operation efficiency of DSO
and reduce the impact of the multi-microgrid on regional power grid. The feasibility of the game strategy is verified by simulation cases.
