AI Technical Summary

Problems solved by technology

If the power transmission capacity between regions is overestimated, the safety and reliability level of the system will be reduced, and dangerous accidents will easily occur in emergency situations.
Underestimating the power transmission capacity will make the existing resources not be fully utilized and reduce the economical efficiency of power system operation.

Abstract

The invention relates to a trans-provincial and trans-regional residual transmission capacity evaluation system, comprising a future-state power grid model construction module, a future operation modematch module, a residual transmission capacity calculation and evaluation module, an auxiliary adjustment module, a data interface module and a visualization module. The system supports trans-provincial and trans-regional channel residual transmission capacity calculation and evaluation work and is capable of rapidly and accurately evaluating the transmission capacity, meeting the regional load electricity utilization to the greatest extent under the premise of satisfying safety and stability constraints, and enabling electricity market participants to gain the maximum benefits.

Description

technical field [0001] The invention relates to the technical field of power grid control, in particular to an evaluation system for cross-provincial residual power transmission capacity. Background technique [0002] The remaining transmission capacity of inter-regional and inter-provincial channels is an important technical index of the power grid. It provides reference for the arrangement of power grid dispatching operation mode and the formulation of power generation plan, and plays an important guiding role in the operation of the power grid. The distance of this constraint can prevent the occurrence of branch overload and node voltage exceeding the limit caused by unreasonable dispatching plan. At the same time, it is also an important indicator to reflect the market signal of grid transmission capacity and measure the feasibility of power trading. With the advancement of power system reform, the volume of direct power purchase transactions (bilateral transactions) by...
