AI Technical Summary

Technical Problem

Traditional methods fail to fully consider the impact of complex terrain in mountainous areas on power generation facilities, especially in high altitude areas, which ignores the weakening effect of topographic height and equipment installation angle on power generation efficiency. The existing grid acceptance capacity assessment is usually based on the theoretical maximum capacity, ignoring the stability of the transmission path and the dynamic changes in load demand, resulting in the deviation of the evaluation results from reality.

Method used

By collecting renewable energy data in the target mountainous areas and performing preprocessing, a renewable energy power generation capacity model and a grid acceptance capacity evaluation model are constructed in the mountainous areas, the total power generation capacity of the power generation facility location and the comprehensive transmission capacity of the power grid are calculated, and the two are coupled to calculate the renewable energy acceptance capacity.

Benefits of technology

It significantly improves the accuracy and reliability of the ability to accept renewable energy in mountain power grids, ensuring the reliability and practicality of the final results.
