Fast analysis of wind power consumption path based on graph theory

With the increasing proportion of wind power in the power supply structure, its impact on the safe and stable operation of the power system is increasingly significant. The contradiction between the development of wind power in some regions and the safe operation of the system is gradually emerging, and the phenomenon of wind abandonment continues to occur. The consumption of wind power has become a key issue affecting the healthy development of China's wind power. Therefore, it is very important to quickly and accurately analyze the absorption path of wind turbines in the whole power grid. This paper uses graph theory to quickly calculate the power composition of transmission lines and the actual power transmission relationship between generators and loads, thus providing a reasonable basis for how to improve the grid structure to improve the wind power absorption capacity. The proposed method is also applicable to the analysis of the relationship between active and reactive power transmission in practical systems. The standard IEEE 14-node system is used for simulation calculation, and the results verify the effectiveness and feasibility of the algorithm.
