Abstract
Reactive power optimization and voltage control of the power system are the key technologies to ensure the safe and stable operation of the power grid. With the large-scale access of new energy and the change of load characteristics, the traditional control methods face many challenges. Therefore, this paper focuses on the construction of reactive power optimization and voltage control system adapted to the characteristics of modern power grid, aiming to improve the operation efficiency and stability of the system. Based on the multi-ob jective optimization theory, a comprehensive evaluation model integrating static and dynamic characteristics is proposed to realize the optimal configuration of reactive power compensation equipment by introducing intelligent algorithm. At the same time, a voltage control strategy is established with a high proportion of new energy. The simulation results show that the proposed method can effectively reduce the network loss, improve the voltage pass rate, and ensure the economy of the system. This research provides a new idea for solving the problem of reactive power and voltage control in complex power system, especially showing good adaptability and robustness in dealing with the uncertainty of new energy, and provides theoretical support and technical reference for the construction of smart grid.
