Research on the Deviation Processing Model of Power Distribution Mode Based on UHV Supporting New Energy Inter-Provincial Power Grid

With the rapid development of UHV transmission technology, UHV cross-provincial power grid supporting new energy has become an important part of the power system. However, due to the imbalance of power demand and resource allocation in various provinces, the deviation of power distribution mode has become an important problem restricting the stable operation of cross-provincial power grid. This paper proposes a power distribution mode deviation processing model based on UHV cross-provincial power grid supporting new energy, aiming to improve the stability and reliability of power grid operation. First, this paper establishes a mathematical model of power distribution mode deviation by deeply analyzing the structure and operation characteristics of UHV cross- provincial power grid. Secondly, in view of the diversity and complexity of power distribution mode deviation, a deviation processing method based on multi-objective optimization algorithm is proposed. By balancing the power supply and demand relationship and optimizing the power distribution strategy, the risk caused by the deviation is effectively reduced. Finally, the effectiveness and feasibility of the proposed model and algorithm are verified by simulation. The results show that the model can significantly improve the operation efficiency and stability of the power grid under different load conditions.
