NOVELTY - The method involves calculating power fluctuation rate of to-be-investigated wind electricity field unit, and scheduling area network according to power fluctuation rate. Smooth upper and lower limits of power fluctuation are calculated, and wind electric field output power is collected. Lithium battery charge state and needed load are provided with maximum allowable value less than or equal to minimum allowable value. A system peak adjusting amount is added to form a new smooth limit reference value and original wind electricity field power prediction value.    USE - Method for controlling a wind electric field energy storage lithium battery in a wind power station.    ADVANTAGE - The method enables providing prediction result and load power requirement of dynamic reference active current to be tested according to a wind power station power unit, by tracking control active current of battery energy storage system. The method enables realizing smooth control of the wind power station output power, and provides response to assertion of the power balance requirement of system. The method enables making the battery to immediately enter into smooth control strategy when the battery is in peak area, so as to ensure smooth and stable output of wind power, and to detect load peak of the battery system in time. The method enables making the battery to enter into smooth control strategy when the wind power is in peak period so as to satisfy load demand and ensure smooth output of wind power.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following:    (1) a wind electric field energy storage lithium battery smooth control device    (2) a wind electric field energy storage lithium battery smooth control device working method.    DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a method for controlling a wind electric field energy storage lithium battery in a wind power station.'(Drawing includes non-English language text)'
