Research on Frequency Control and Optimization of Power Grid Auxiliary Load for Diversified Vehicle Network Interaction

With the transformation of global energy structure and the rapid development of intelligent transportation system, the interaction between power grid and vehicle network has become a research hotspot. Especially the popularization of electric vehicles (EVs) and the progress of smart grid technology play a key role in maintaining the stable operation of power grid, optimizing energy distribution and improving the reliability of power system. The purpose of this study is to deeply discuss the frequency control and optimization of auxiliary load in power grid under the background of diversified vehicle-network interaction, and put forward effective control strategies through analysis and research. The research methods include establishing a fusion model of power grid and vehicle network, proposing an auxiliary load control strategy based on vehicle battery and fleet scheduling, and using MATLAB/Simulink for simulation analysis. Through simulation analysis, the effectiveness of the proposed strategy is verified, including adjusting the charging and discharging behavior of EV to stabilize the power grid frequency, optimizing the dispatching plan of bus fleet to improve the power grid frequency stability and so on. It is of great theoretical and practical significance to study the frequency control and optimization of auxiliary load in power grid for diversified vehicle-network interaction. The strategies and methods put forward in this study not only help to improve the stability and efficiency of power grid, but also help to promote the further development of intelligent transportation system and contribute to the realization of energy saving, emission reduction and sustainable development goals.
