摘　　要：微电网系统由直流配电和交流配电两部分组成,包含光伏和风力发电、储能装置、微型燃气轮机和交直流负载,并通过PCC并网点接入大电网。交直流混合微电网结构的能量管理核心是根据交直流母线的电压频率状态,控制各发电系统、双向功率变换器和储能装置工作在合适的模式,使微电网内部功率保持平衡,既提高新能源的利用率,又提高系统供电的可靠性。该微电网系统通过Matlab/Simulink仿真,验证了可行性和有效性。The micro grid is made up of AC/DC hybrid, including photovohaic, wind power generation, storage device, micro gas turbine and the AC/DC load, and it ean be connected to the power grid through PCC. The core of hybrid mierogrid energy management ean keep the power balance of mierogrid through the power balance state of the AC/DC subgrids and controls each power systems. The dual power eonvert and energy storage devices keep the balance of micro grid inner power, which improves the utility of new energy and the reliability of power supply. The feasible and effective of micro grid are verified through Matlab/Simulink simulation.
