论文摘要
本文从网络物理的角度解决了岛状微电网（MG）的分布次级电压控制问题。事件触发的分布式模型预测控制（DMPC）方案旨在调节每个分布式发电机（DGS）的电压幅度，以在控制性能和通信和计算负担之间取得更好的权衡。通过使用两个新型的事件触发条件，可以轻松嵌入DMPC以应用MG控制，并且随着控制性能的损害可忽略不计，计算和通信负担大大降低。此外，为了降低传感器成本并消除非线性的负面影响，使用自适应的非反应观察者来估计每个DG的内部和输出信号。多亏了无与伦比的观察属性，观察者可以定期应用与基于DMPC的电压调节器合作。最后，已通过几种代表性的方案在具有4个DGS和修改的IEEE-13测试系统的简单配置上测试了所提出的控制方法的有效性。
This paper addresses the problem of distributed secondary voltage control of an islanded microgrid (MG) from a cyber-physical perspective. An event-triggered distributed model predictive control (DMPC) scheme is designed to regulate the voltage magnitude of each distributed generators (DGs) in order to achieve a better trade-off between the control performance and communication and computation burdens. By using two novel event triggering conditions that can be easily embedded into the DMPC for the application of MG control, the computation and communication burdens are significantly reduced with negligible compromise of control performance. In addition, to reduce the sensor cost and to eliminate the negative effects of non-linearity, an adaptive non-asymptotic observer is utilized to estimate the internal and output signals of each DG. Thanks to the deadbeat observation property, the observer can be applied periodically to cooperate with the DMPC-based voltage regulator. Finally, the effectiveness of the proposed control method has been tested on a simple configuration with 4 DGs and the modified IEEE-13 test system through several representative scenarios.
