Abstract As a significant component in AC-DC hybrid microgrid, Bi-directional AC-DC converter plays an important role in stabilizing system as well as adjusting allocation of power. In this paper, a novel control strategy for Bi-directional AC-DC converter based on switched system modeling has been established. First, a switched dynamic modeling is established. A common Lyapunov function is proposed based on the system energy storage function. Then an optimal switching sequence is proposed and the system stability is analyzed. In order to facilitate the controller digital implementation, the discrete control strategy is proposed. At last, the modeling approach and control strategy is validated by both simulation and experiment.

Key words： Bi-directional AC-DC converter switched modeling current control hybrid microgrid forecasting
