First storage battery unit includes a first converter that converts alternating current and direct current, a first storage battery, and a first controller that controls first converter, and first storage battery unit is interconnected to a system for supplying power. The first controller detects a frequency of the system, and controls first converter such that first storage battery outputs constant active power to the system on the basis of the frequency of the system falling below a first threshold value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Storage battery system and method for suppressing fluctuation in frequency of AC power system","description":"A storage battery system includes a first storage battery unit.
