1. consider a polymorphic type energy-storage system energy management method for operation and maintenance, it is characterized in that, described method comprises the steps:

  • (1) related data of wind-light storage electricity generation system and battery energy storage system is read;

    (2) the filter order fiducial value that draws of normalized modulus cumulative mean value, resolves into high frequency, intermediate frequency and low frequency signal by power signal;

    (3) current time energy-storage system active power and state-of-charge is asked for, and judge whether the state-of-charge of current time energy-storage system exceedes preset value, if exceed, then stop power smooth controlling, otherwise revise energy-storage system power command value in real time according to the state-of-charge of energy-storage system and actual power;

    (4) judge the charging and discharging state of energy-storage system according to the symbol of energy-storage system active power, and calculate the active power bid value of each energy-storage battery unit based on energy-storage system charging and discharging state.
