CHARGE/DISCHARGE METHOD FOR ENERGY STORAGE SYSTEM AND ENERGY STORAGE CABINET

A charge/discharge method for energy storage system and energy storage cabinet includes: acquiring peak-valley electricity price information, load power prediction result, and/or energy storage system charge level information; determining, based on peak-valley electricity price information, energy state interval of target time period; determining, within energy state interval of target time period, charging/discharging amount in target time period based on load power prediction result and/or energy storage system charge level information; determining charging/discharging power in target time period based on charging/discharging amount in target time period, duration of target time period, current ambient temperature, thermal management strategy of energy storage system, and/or corresponding relationship between conversion efficiency and power of power conversion system. It is conducive to dynamically adjusting charge/discharge plan and generating reasonable charge/discharge plan, which solves problems of efficiency loss and revenue reduction of energy storage system due to unreasonable configuration of charge/discharge plan.
