"基于VMD技术与混合储能策略的风电并网控制方法"

Based on the VMD technology and hybrid energy storage strategy, a wind power grid connection control method is proposed to address the adverse effects of wind power fluctuation and randomness on the stable operation of the power grid. The method involves the decomposition of the original power of typical wind power output scenarios using variational mode decomposition (VMD) technology, and then the power is divided into grid-connected power and storage power based on the wind power grid connection power fluctuation standard. By suppressing wind power fluctuations, the method achieves maximum power grid connection while ensuring the optimal decomposition and reasonable allocation of wind power. Furthermore, the method involves the primary allocation of storage power based on the response characteristics of energy storage components. The state of charge (SOC) of supercapacitors is monitored internally within the system, and a fuzzy control is used to make a secondary adjustment to the primary power of the energy storage components. Simulation results show that this control strategy effectively suppresses wind power grid connection power fluctuations while ensuring maximum power absorption, and also ensures that the state of charge of the energy storage components remains stable within a safe range, greatly extending the lifespan of the energy storage components. In conclusion, the proposed wind power grid connection control method based on VMD technology and hybrid energy storage strategy effectively addresses the challenges posed by wind power fluctuations and randomness, ensuring the stable operation of the power grid and maximizing the utilization of wind power while prolonging the lifespan of energy storage components. This method has the potential to significantly contribute to the development of efficient and sustainable wind power integration into the power grid.
