A game theoretic approach for distributed generations in DC microgrid

This paper presents a new control strategy for distributed generations (DGs) in a DC microgrid. The proposed technique is derived based on game theory and is independent of the communication network. In the presented paper, the operation of the DC microgrid with non-communication structure is regarded as a non-cooperative game. With reasonable game mechanisms, the operation of the DC microgrid converges to a stable equilibrium, known as Nash equilibrium. Compared with the traditional droop control, the proposed approach eliminates the trade-off between the power sharing accuracy and the output voltage deviation. Finally, the simulation and experimental results corroborate the theoretic analysis.
