摘要:
利用MAS技术，以某高校校园微电网为模型，我们设计了一种微电网孤岛运行时黑启动策略。以单轴微型涡轮机为主启动电源，燃料电池为参考电源，具有黑启动能力的分布式电源同时启动，接入各自的受保护负荷，形成多个子微电网。再根据参考电源的电压、频率，各子网络同步后并联运行。黑启动最后阶段无黑启动能力的分布式电源从低压电网吸收功率启动，各分布式电源在微电网中央管理层的调配下改变控制方式，协调电源的输出功率，使微电网持续、稳定、高效地运行。通过Matlab/Simulink平台上搭建仿真模型，仿真结果验证了该黑启动策略能独立自主、稳定快速地实现微电网故障瘫痪后的黑启动。
A strategy of black-start based on MAS is proposed for isolated microgrid, which builds in a uni-versity campus. The SSTM is used as chief start-up power; fuel cell power provides reference and voltage. Distributed power with black-start capabilities starts at the same time; every source sup-plies the power to the load which they protect. According to the voltage and frequency from the fuel cell, every subnetwork runs synchronously. At last, the distributed power without black-start capabilities gets power from the low-voltage grid to start-up. Every distributed power changes their control method under the control of MGCC agent, the MGCC coordinates the power to make microgrid continuously, stably and efficiently. Based on the Matlab/Simulink platform, built the simulation model, the simulation results verify that the black-start strategy can achieve the goal of black start independently and stably after micro-grid fails.
