A New Triple Bargaining Game-Based Energy Management Scheme for Hierarchical Smart Grids

This paper deals with the hierarchical structure of smart-grid systems. The major challenges of this structure are to balance electric power production and consumption within the hierarchical smart grid, and makes active use of the flexibility of a large number of power producing and consuming units. In this study, we present a new triple game based energy management scheme for the hierarchical smart-grid architecture. By using the Nash with claim, midpoint-constrained egalitarian and proportional bargaining solutions, the proposed approach can adaptively distribute the limited energy resource of smart-grid system. To reduce the computation complexity, these bargaining solutions are hierarchically applied based on the developed triple game model. According to the attractive characteristics of each bargaining solution, control decisions in our proposed scheme are mutually dependent on each other and can cause cascade interactions to reach a desirable system performance. The results obtained from the simulation analysis illustrate the effectiveness of the proposed scheme compared with the existing state-of-the-art protocols. Finally, we conclude advantages of our triple game based energy management scheme and identify research areas for future study.
