A threshold storage unit stores a discharge control threshold for determining whether to discharge remaining storage cell power. When demand power exceeds generated power, a command unit controls storage cell discharge by comparing remaining storage cell power with the discharge control threshold and transmits a control command to a power conditioner. If the remaining storage cell power exceeds the discharge control threshold, then the command unit commands storage cell discharge. A threshold setting unit sets the discharge control threshold, and updates the discharge control threshold when that value changes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply system","description":"A demand measurement unit measures load demand power and a power generation measurement unit measures solar cell output power.
