Abstract This paper proposes a novel control method for improving AC interconnected grid dynamic stability using energy storage technology, by configuring the inter-area mode corresponding eigenvalue and damping the inter-area mode effectively even in the case of the capacity of the energy storage device is limited. The optimization of the control coefficients and the selection of energy storage installation site are discussed. The influence of the response time on control effect is analyzed and the practical control strategy is proposed. The validation of the control method is verified by digital simulations. Satisfactory results in the case of limited storage power are obtained.

Key words： Energy storage technology AC interconnected grids low frequency oscillation dynamic stability eigenvalue configuration
