| 摘要: |
| 利用多代理（Agent）系统，提出了一种针对全黑的孤立微电网的黑启动策略。参考电源及其他具有黑启动能力的微电源首先由微电网中心控制（MGCC）Agent以电压控制模式启动，再根据参考微电源的电压进行预同步后进行并联。接着，具有黑启动能力的微电源切换至PQ控制模式，其输出功率和电流被功率锁存功能锁定以避免切换振荡。最后，无黑启动能力的微电源被MGCC Agent以PQ 控制模式启动，在与参考电源进行同步后并入微电网。MGCC Agent 通过协调微电源的输出功率，使微电网可以高效、稳定地运行。微电网稳定运行后，由主网-微电网控制（GMＧC）Agent恢复微电网与大电网的连接。利用MATLAB／Simulink建立微电网仿真模型，仿真结果验证了所提策略是高效、可行的。 |

| Abstract: |
| A strategy of black-start based on multi-Agent system is proposed for isolated microgrid，which starts up in voltage control mode the reference microsources and microsources capable of black-start by MGCC（MicroGrid Central Control） Agent first，carries out then the pre-synchronization and grid-connection for the reference microsource according to its voltage，switches then the microsource capable of black-start into PQ control mode while blocks its power and current outputs with the power latch function to avoid switching oscillation，and at last，starts up in PQ control the microsources incapable of black-start by MGCC Agent，synchronizes them with the reference microsource and connects them to microgrid. MGCC Agent coordinates the power output among microsources to make the microgrid operate efficiently and stably，and then GMGC（Grid-MicroGrid Control） Agent connects the microgrid to power grid. A simulation microgrid is built with MATLAB／Simulink and the simulative results verify the feasibility and effectiveness of the proposed strategy. |
