【摘要】：针对含多个分布式电源的微电网协调控制问题,根据电源特性的不同分别进行了控制器设计。运用多智能体技术将集中控制和分散控制有效结合起来,保证微电网在孤岛运行和联网运行模式之间切换时系统稳定运行,基于多智能体技术的能量管理系统对分布式电源的输出进行优化分配。电压/频率控制采用一个与配电网频率同步的正弦信号作为参考电压,控制结构简单且响应速度快,在确保系统的稳定的同时使得微电网频率与配电网维持同步,降低了重新并网的难度。通过PSCAD软件对微电网在不同运行模式下的分布式电源输出和负载变化进行仿真,对结果的分析表明提出的控制结构是正确有效的。
[Abstract]:Aiming at the coordination control problem of microgrid with multiple distributed power sources, the controller is designed according to the different characteristics of the power supply, and the centralized control and decentralized control are effectively combined by using multi-agent technology. To ensure the stable operation of the microgrid system when the island operation and the switching between the operation mode of the network, The energy management system based on multi-agent technology optimizes the output of distributed generation. A sinusoidal signal synchronized with the frequency of the distribution network is used as the reference voltage in the voltage / frequency control. The control structure is simple and the response speed is fast. In order to ensure the stability of the system, the frequency of the microgrid is kept in sync with the distribution network, and the difficulty of reconnection is reduced. The distributed generation output and load change of the microgrid under different operation modes are simulated by PSCAD software. The results show that the proposed control structure is correct and effective.
