<p>An innovative approach to’intelligent regulation and control of major parts of the power grid is suggested to improve the stability and productivity of the large-scale integration of new energy grids. Using data analysis, the application research of intelligent control technology of the grid section in new energy grid-connected systems is suggested, and the use of intelligent regulation technology of the power grid section in large-scale new energy grid-connected operation is examined. This attempts to enhance the stability and operation effect of renewable energy integration and is driven by the unsatisfactory operation effect of large-scale new energy grid-connected operation.The methodology will be the analysis of tie line power exchanges and the formation of an intelligent control model of power distribution by means of recursive multi-level optimization. The piece presents a new smart control policy of large blocks of a power grid. First, the factors influencing the power grid's transient voltage stability after the new energy grid connection is made are examined. Next, the power exchange of the contact line is examined in order to propose an intelligent regulation strategy for the power grid section, build a power control model for the contact line, and finish the application research of the grid section's intelligent control technology in the large-scale new energy grid connection. The mathematics of simulation experiments indicate that the proposed technique can achieve a maximum of a saving of 42.54 percent of the energy as opposed to the traditional energy grid-connected and cross-section control techniques.Lastly, the simulation experiments demonstrate that the application analysis conducted in this research has good application effects and can successfully increase the stability of large-scale new energy grid-connected operation.</p>
