The invention belongs to the technical field of power systems, and particularly relates to a coordination method and system for source-load power balance of a distribution network. The method comprises the steps that grid division is carried out on a distribution network system, each grid comprises a power supply and a load, and the power supplies comprise a new energy power supply and a traditional power supply; when the power supply total power and the load total power of a grid are unbalanced, new energy power is transferred to or extracted from other specified grids according to the difference value of the power supply total power and the load total power in the grid, and the transferred or extracted new energy power refers to the power with the corresponding difference value provided by a new energy power supply; and if the new energy power is still unbalanced after being transferred or drawn to other specified grids, the power of the traditional power supply in the grid is coordinated by using the distribution network monitoring system, so that the total power of the power supply and the total power of the load in each grid are balanced, and the communication pressure, the coordination difficulty and the coordination time during the balance coordination of the source and load power of the distribution network are reduced.

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. By monitoring the load flux density of logical partitions in real time to construct a nonlinear dynamic virtual impedance, and combining it with the correlation coupling degree model to calculate the comprehensive acceptance potential energy, load scheduling instructions are generated. This invention utilizes an embedded negative feedback saturation suppression loop to exponentially increase the impedance when the flux density approaches the threshold, forcibly suppressing the load adsorption capacity of high-heat nodes, and realizing dynamic power balance between energy flow and information flow within the system.

The invention belongs to the technical field of power system regulation and control, and particularly relates to a regulation and control method and system for power balance of a distribution network system. The method comprises the steps that grid division is carried out on a distribution network system, each grid comprises a power supply and a load, the power supply comprises a new energy power supply and a traditional power supply, and the load comprises a flexible load; when the total power of the power supply and the total power of the load in the grid are unbalanced, regulating and controlling the power of the flexible load or the power of the new energy power supply in the grid in situ according to the total power of the power supply and the total power of the load in the grid; if the grid is still unbalanced after regulation and control, the distribution network monitoring system is used for regulating and controlling the traditional power supply power in the grid, so that the total power supply power and the total load power in each grid are balanced, the regulation and control time is shortened, the communication and operation pressure of the distribution monitoring system is reduced, the source load power in the grid can be quickly balanced, and the power of the whole distribution system is further quickly balanced; electricity utilization requirements of different types of loads are met, and overall reliable operation of a distribution network system is guaranteed.
