| 摘要: |
| 在独立交流微电网系统内，微型燃气轮机与储能蓄电池的协调控制是保证独立微电网稳定运行的关键。首先建立了光伏、微型燃气轮机、蓄电池的模型；再根据不同微电源的特性，采用下垂控制或PQ控制的控制方法；然后，建立了微型燃气轮机与蓄电池的协调控制，针对切换过程中的短时停电，提出微型燃气轮机与蓄电池间的无缝切换控制策略；最后，在PSCAD／EMTDC仿真软件上进行了仿真验证。仿真结果表明所提协调控制方法能保证在切换过程中对系统的冲击小，影响时间短，实现了无缝切换。 |

| Abstract: |
| The coordinated control of storage battery and microturbine is essential to the stable operation of islanded AC microgrid. The models of photovoltaic cell，microturbine and battery are established；Droop control or PQ control is adopted according to the characteristics of microsource to be controlled；the coordinated control of microturbine and battery is established and the control strategy of seamless switching between them is proposed to avoid the short-time outage. Simulative verification is carried out with PSCAD／ EMTDC simulation software and results show that，the coordinated control realizes the seamless switching，ensuring the small and short-time impact on system during switching process. |
