柔性聚合体虚拟惯量调频控制方法及电子设备
By using the flexible polymer virtual inertia frequency regulation control method, model predictive control is used to optimize the coordinated frequency regulation of heterogeneous energy sources. The virtual inertia control coefficient is dynamically adjusted, which solves the overshoot and excessive operation of energy storage devices in the frequency recovery stage of the existing technology, and improves the frequency stability and frequency regulation capability of the power system.
