The invention provides a micro power grid hybrid energy storage coordinative frequency modulation method. A micro power grid comprises hybrid energy storage equipment. The hybrid energy storage equipment at least comprises energy storage devices from a first type to a third type. The method comprises the steps of: obtaining total power, which needs to be emitted or absorbed by the hybrid energy storage equipment, according to a current voltage frequency of an alternating current bus in the micro power grid and a frequency reference value; and utilizing a preset low-pass filter and high-pass filter to carrying out distribution on the total power which needs to be emitted or absorbed by the hybrid energy storage equipment, wherein first power distributed by the low-pass filter is emitted or absorbed by the first type of energy storage device, residual second power after the distribution of the low-pass filter and the high-pass filter is emitted or absorbed by the second type of energy storage device, and third power distributed by the high-pass filter is emitted or absorbed by the third type of energy storage device. By adopting the method, the energy storage devices of different types are uniformly managed and are applied to a micro power grid system for carrying out micro power grid frequency modulation, so that the stability of the frequency of the micro power grid system is realized.
