电力系统中分布式发电数量的不断增加提出了对快速且可扩展的分布式控制算法的需求。本文提出了一种用于二次频率控制的分布式模型预测控制，该控制详细模拟电网区域内的动态，同时通过系统等效考虑其他区域的动态。分布式优化算法保证了控制解的一致性。控制器通过测量边界总线处的等效系统阻抗来适应不断变化的系统条件。使用宽带频率阻抗设备进行测量，然后进行复杂曲线拟合，以提取电网阻抗的传递函数。此外，该算法只需要来自其他网格区域的聚合信息，从而减少了脆弱性并增加了每个区域的隐私性。通过数值模拟验证了分布式模型预测控制器的性能。
The increasing number of distributed generation in the power system raises the need for fast and scalable distributed control algorithms. This paper proposes a distributed model predictive control for secondary frequency control that models the dynamics within a grid area in detail while considering the dynamics of other areas through a system equivalent. Consistency of the control solution is ensured by the distributed optimization algorithm. The controller adapts to changing system conditions through the measurement of the equivalent system impedance at the boundary bus. A measurement using a wideband-frequency impedance device followed by complex-curve fitting is used to extract the transfer function of the grid impedance. Furthermore, only aggregated information from other grid areas is required by the algorithm, reducing vulnerability and increasing the privacy of each area. The performance of the distributed model predictive controller is verified through numerical simulations.
