Power grid key transmission section limit transmission capacity calculation method with consideration of artificial scheduling knowledge

Abstract

A power grid key transmission section limit transmission capacity calculation method with consideration of artificial scheduling knowledge includes the steps of S 1) definition of an electricity generation area and a load area; S 2 definition of an electricity generation load increasing mode; S 3 calculation of key transmission section limit transmission capacity by the adoption of a continuous power flow mode. According to the power grid key transmission section limit transmission capacity calculation method with consideration of the artificial scheduling knowledge, the continuous power flow mode of an electricity generation area load area definition mode and the electricity generation load increasing mode with the consideration of the artificial scheduling knowledge is adopted to calculate the key transmission section limit transmission capacity, so the calculation result of the key transmission section limit transmission capacity is fitter for a power grid practical operational mode, adaptability of the key transmission section limit transmission capacity for power grid practical on-line operation is improved, and the result is more real and believable.

Description

technical field [0001] The invention relates to a method for calculating the limit transmission capacity of a key section of a power grid, in particular to a method for calculating the limit transmission capacity of a key section of a power grid considering manual scheduling knowledge. Background technique [0002] In today's power system operation, in order to ensure the safe and stable operation of the power grid, the power system operation department often formulates a series of operating rules for the power system to limit the power system to a certain safe operating space. An important part of these operating rules is the limit transmission capacity of key sections of the power grid. By limiting the transmission power of key sections of the power grid, the effect of ensuring the safe operation of the power grid is achieved. [0003] When the key section is selected, the calculation result of the critical section’s ultimate transmission capacity will be affected by many ...

Problems solved by technology

[0007] 1. The calculation uses all the power generation side as the power generation area and the load side as the load area, which does not conform to the definition mode of the power generation area and the load area of ​​the key section of the power grid in actual operation, and has poor adaptability to the actual operation of the power grid;

[0008] 2. The calculation adopts an extremely unfavorable power generation load growth mode, which is difficult or basically impossible to appear in the actual power grid operation. It does not conform to the definition mode of the power generation load growth mode of the key sections of the power grid in actual operation, and is less adaptable to the actual operation of the power grid.
