Method and apparatus for balancing power among power grid partitions

Abstract

The invention discloses a method and apparatus for balancing power among power grid partitions. The method includes the following steps: partitioning a power grid within an object area to obtain a plurality of grid partitions; based on the power supply output power, tie-line power, and load occupancy power of each grid partition, computing the state of output balance of each grid partition; transmitting the redundant output power of grid partitions which are at a rich state in terms of output balance to grid partitions which are at an inadequate state in terms of output balance, thus realizing power balance among grid partitions. Therefore, the method firstly divides the power grid within the object region into a plurality of grid partitions, further computes the state of output balance of each grid partition based on the power supply output power, the tie-line power and the load occupancy power of each grid partition, and transmits the redundant output power of grid partitions which are at a rich state in terms of output balance to grid partitions which are at an inadequate state in terms of output balance, and thus implementing power balance of different grid partitions through the transmission of output power.

Description

technical field [0001] The present invention relates to the field of electric power technology, and more specifically, relates to a method and device for balancing electric power between grid divisions. Background technique [0002] The whole composed of substations of various voltages and transmission and distribution lines in the power system is called the power network, referred to as the power grid, which includes three units of power transformation, power transmission, and power distribution; . [0003] In the prior art, for a power grid in a large area, such as a province, the output power of the power grid is often not balanced, that is, the output power of some areas in the power grid is greater than the required power, and the output power of some areas is less than the required power. This imbalance leads to poor power supply reliability of the grid. [0004] To sum up, how to provide a technical solution for realizing power balance between sub-regions of the pow...
