摘要

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.%为了在储能功率有限的情况下能够更有效地阻尼系统低频振荡,提出了一种利用储能技术提高交流互联电网动态稳定性的控制方法,即利用储能技术配置区域间振荡模式对应特征根、增大系统区域间振荡模式的阻尼。研究了储能装置控制参数的优化和安装地点的选取,分析了储能装置功率响应时间对所提方法控制效果的影响,提出了实用化的控制策略,并进行了仿真分析。结果表明,所提控制方法在储能功率有限的情况下,仍然具有令人满意的控制效果。
