CONTROL METHOD FOR ENERGY STORAGE SYSTEM OF MICROGRID

摘要

The present specification relates to a control unit and a control method for controlling a battery unit that stores energy generated by various energy sources of a micro grid. The control unit of the grid uses a heating unit or a cooling unit to increase or decrease the temperature of the battery unit while discharging (or charging) the battery unit. It illustrates a battery unit, a control unit, and a related control method that can minimize irreversible damage. In addition, the present specification relates to a battery unit and a related control method in which some batteries are mounted to facilitate replacement. For example, a number of batteries are divided into separate batteries or separation packs that are easy to separate, and fixed batteries or fixed packs that are relatively difficult to separate, and then mounted on the battery unit, and discharged at low or high temperatures outside the appropriate temperature range ( Or charging) can be selectively dedicated to the separation battery (or separation pack). Thus, the control unit allows the separate battery to suffer more irreversible damage, while the damage to the stationary battery can be minimized. In addition, when a user replaces a damaged battery (or battery pack) in the future, a number of fixed batteries (or fixed packs) can remain in the battery unit and only a few separate batteries (or separation packs) can be replaced, so the capacity is reduced. The cost of replacing lost batteries can also be reduced.
