Abstract
With the continuous expansion of power system scale and the rapid growth of electricity load, the reasonable compensation of reactive power and the effective optimization control of voltage have become key issues to ensure the safe and stable operation of the power grid. This study aims to explore the theories and methods of reactive power compensation and voltage optimization control in power systems, proposing an improved algorithm based on a multi-ob jective optimization model for achieving efficient reactive power distribution and precise node voltage regulation. By integrating modern intelligent optimization techniques, this research introduces an adaptive particle swarm optimization algorithm combined with hierarchical and zonal control strategies, utilizing a dynamically constructed sensitivity matrix to evaluate the coupling relationships between nodes, thereby significantly enhancing the convergence speed and solution accuracy of the algorithm. Simulation results demonstrate that the proposed method effectively reduces network losses, improves voltage qualification rates, and exhibits excellent robustness and adaptability under various operating conditions. Furthermore, this study innovatively incorporates distributed generation scenarios into the analytical fr amework, verifying the applicability of the proposed strategy in power systems with high proportions of renewable energy. Overall, this research provides new theoretical support and technical approaches for reactive power compensation and voltage optimization in power systems, playing a significant role in advancing the development of smart grids.
