Data collection agents are assigned to storage area network nodes in a storage area network resource management system, such that the bandwidth and cost of data collection are equitably distributed among data collection agents. Data collection overlaps and load imbalances are eliminated across the data collection agents, creating approximately equal partitions of bandwidth and data collection for each data collection agent. Graph partitioning is used to accomplish load balancing. The assignment of data collection agents to storage area network nodes equitably distributes the bandwidth and processing costs among the data collection agents and ensures a load balance.

The invention discloses a method and a system for stabilizing a power grid. The method includes the following steps: when a power failure occurs in a substation on the high-voltage side, a low-cycle load shedding device sends a locking signal to a fast switching device of a low-voltage side distribution room through a communication line; and the fast switching device of the low-voltage side distribution room enters a disenabled state according to the locking signal, wherein the low-voltage side distribution room is connected with multiple pieces of electric equipment through a change-over switch, the low-voltage side and the high-voltage side are connected by a pair of power feeders, and the communication line is used to transmit the locking signal. The technical problem in the related technology that the low-voltage side distribution room cannot be accurately switched off when the cycle wave of the power grid failure system collapses is solved, and the technical effects of power consumption balancing and power grid stabilizing are achieved.

The invention relates to an active adjustment method for realizing low-frequency load shedding capacity based on power grid topology, which comprises the following steps of: selecting a section, and determining an initial node of a local power grid based on the section; reading the real-time power flow value of the section and the low-frequency load shedding capacity of the local power grid, and calculating the low-frequency load shedding capacity deviation ratio according to the real-time power flow value and the low-frequency load shedding capacity of the local power grid; performing power grid topology analysis based on the initial node, searching all nodes communicated with the initial node to obtain a power grid topology structure of the local power grid, and screening out a tail end switch; establishing a power grid low-frequency load shedding information table, adding low-frequency load shedding rounds, and adding an operation item for each low-frequency load shedding round; according to the sequence in the power grid low-frequency load shedding information table and the low-frequency load shedding capacity deviation ratio, the screened tail end switches are selected, and a low-frequency load shedding sequence table is generated; and according to the low-frequency load shedding sequence table, the low-frequency load shedding device in the tail-end switch interval is remotely controlled to be switched on and switched off, and active adjustment is completed.
