Abstract

In order to improve the power angle and voltage stability of the sending end power grid, this paper first establishes the model of the external sending end system of new energy power generation, and optimizes the new energy output based on the stability of the sending end power grid. Secondly, the system power angle and voltage change under disturbance are analyzed, and the virtual power angle model of new energy power generation is established. Then, a power angle stability control model based on energy fluctuation is established to analyze the influence of energy fluctuation on power angle stability. Finally, aiming at the minimum power angle deviation and the maximum transient stability margin of the sending end power grid, the multi-objective optimization algorithm based on neural network is used to calculate, and the effectiveness of the proposed method is verified by simulation.
