The application discloses a new energy fluctuation-based power balance evaluation method and device, and belongs to the technical field of power balance. When the singular value in the performance parameter value of the new energy is replaced and handled via the performance parameter value mode, the number of parameters sent to the performance parameter value handling mode will affect the accuracy of the parameters obtained after the singular value is replaced. If the number of parameters sent to the performance parameter value handling mode is not large, the small number of singular values will have a considerable effect on the accuracy of the parameters obtained by the mode handling. If the number of parameters sent to the performance parameter value handling mode is not small, the strength of the flexible handling of the singular values is usually not large, so the number of sent parameters of the parameters handled by the most appropriate mode is obtained according to the fluctuation amplitude of the parameters and the number of singular values identified by the singular value algorithm, the mode is added to the sent parameters, and the derived parameters are more accurate.

This invention relates to the field of smart microgrid energy management technology and discloses an integrated smart footwear storage location management system, including a distributed resource storage module, a load flux coupling monitoring module, a dynamic virtual impedance generation module, and a load balancing scheduling control module.
