Problems solved by technology
[0004] However, it does not solve the problem that in the prior art, the power supply relationship between different substations and different grid power supply areas cannot be selected according to the different power consumption conditions of different grid power supply areas, and the electric energy of the substations cannot be used to provide power for the power supply areas. To effectively guarantee the power supply effect, we propose a grid partition method based on the maximum power supply capacity

The invention discloses a power grid partitioning method based on the maximum power supply capacity, and belongs to the field of power transmission systems, the power grid partitioning method based on the maximum power supply capacity comprises the following steps: determining coordinates of a transformer substation on a map, and dividing a power supply area to be divided into a plurality of grid power supply areas; recording power consumption values of each grid power supply area in different time periods; according to the power utilization values of the grid power supply areas in different time periods, calculating a proportion value Y of the power utilization scores Y1 of the grid power supply areas in each time period to the total power utilization value Y2; the grid power supply areas are divided into a deep electricity utilization area, a middle electricity utilization area and a shallow electricity utilization area according to the proportion value Y of the grid power supply areas in the same time period, and the power supply relation between different transformer substations and different grid power supply areas can be selected according to different electricity utilization conditions of different grid power supply areas; therefore, the electric energy of the transformer substation is utilized to supply power to the power supply area, and the power supply effect is ensured.
Description
technical field [0001] The invention relates to the field of power transmission and distribution systems, and more specifically, to a grid partitioning method based on maximum power supply capacity. Background technique [0002] For a long time, the power grids in many cities in my country have suffered from insufficient power supply capacity, uncertain network transfer capabilities, low utilization of power grid equipment, unbalanced loads, and large losses. The power system is facing increasingly heavy planning tasks, which put forward higher requirements for the planning and operation of the power grid, and the optimization of power supply partitions in the power grid has become a problem worthy of attention. [0003] For example, a distribution network zoning method based on the maximum power supply capacity disclosed in the application publication number CN104836224A, although it can obtain an accurate optimal zoning scheme, and make the zoning faster, making the distri...
