Research on Microgrid Capacity Planning based on Cooperative Game

To address the problem of cost sharing among multiple economic agents participating in microgrid capacity planning, it is proposed that the formulation of binding agreements is the key to the cooperative game that can be realized ultimately. Firstly, the conditions that need to be satisfied by the cost sharing strategy of cooperative game in islanded wind-photo-hydrogen storage microgrid system are given, i.e., overall rationality, coalition rationality and individual rationality. Secondly, four cost-sharing strategies are used to cost-share the total economic cost in the fully cooperative game, and the acceptance degree of each game participant in the cooperative game process is measured by the MDP (modified disruption propensity, MDP) index. Finally, taking the actual wind speed and light intensity of a place in Northwest China as an example, it is verified that the cost sharing strategy based on equal MDP index and Shapley value is more attractive to all parties and belongs to the core set, which is a binding cost sharing strategy.
