Aiming at the independent AC/DC microgrid, a simple and effective multi time scale control strategy is proposed by adopting the combination of day ahead scheduling and real-time control. The day ahead scheduling strategy takes the minimum operation cost of AC/DC microgrid as the goal, and schedules the controllable loads in the AC/DC microgrid with particle swarm optimization, which makes full use of renewable energy. The real-time control strategy controls the output of the distributed generation, the load reduction and the switching of the diesel generator according to the real-time energy storage state of charge (SOC), which keep the power balance of the AC/DC microgrid. The effectiveness of the proposed two-level control strategy is verified by a practical AC/DC hybrid microgrid. The results show that the proposed method can make full use of renewable energy and ensure the economic and reliable operation of AC/DC hybrid microgrid.
