Damping control method and system suitable for hybrid energy storage power station

The invention discloses a damping control method and system suitable for a hybrid energy storage power station. The system runs in a hybrid energy storage power station or a new energy power station master control system containing hybrid energy storage, and when low-frequency oscillation of a power grid is detected, an oscillation energy flow smaller than zero can be provided to suppress low-frequency oscillation of the power grid. The system can perform graded adjustment according to response capabilities of different types of power generation equipment and energy storage equipment in a power station so as to make full use of the adjustment performance of the equipment and meet different adjustment requirements, and aims to achieve a better adjustment effect under different adjustment requirements, prolong the service life of the power generation equipment and the energy storage equipment, and improve the power generation efficiency. And the comprehensive cost caused by adjustment is reduced. 本发明公开一种适用于混合储能
