In the view of the situation that structure of micro-grid and its control strategy are very complex, as well as difficult to fast implement and expand, this paper proposes a practical engineering stand-alone microgrid based on distributed photovoltaic generation, to realize fast construction and safe and efficient operation. The key technologies such as construction and operation mechanism, the power electronic device development, and energy management and dispatch strategy are studied. Based on the topology, the demonstration microgrid composed of photovoltaic, diesel generator, and storage battery is constructed on the island, and an uninterruptible power supply is produced. Operation test analysis of the stand-alone microgrid verifies the effectiveness of the microgrid architecture, and some suggestions are recommended for the problems existed.
