Abstract
In the power system, the optimal control of reactive power and voltage is the key link to ensure the safety, stability and economic operation of the power grid. With the increase of power load and the complexity of power network structure, the precise control and optimal management of reactive voltage are required. The ob jective of this paper is to discuss the optimal control strategy of reactive voltage in power system and its realization. This paper describes the importance of optimal control of reactive voltage. Voltage is an important index of power quality, and reactive power is a key factor affecting voltage quality. The optimal control of reactive voltage can not only improve the voltage quality, reduce the line loss, but also enhance the stability and economy of the power grid. In the power system, the optimal allocation and efficient utilization of grid resources can be realized by adjusting the distribution of reactive power and voltage level reasonably. This paper analyzes the main strategies of reactive voltage optimization control. These strategies include reactive power optimization calculation based on intelligent optimization algorithms such as genetic algorithm and particle swarm algorithm, and hierarchical decentralized control based on automatic reactive voltage control device (VQC) in substation. Each of these strategies has its own advantages and disadvantages, but the common goal is to achieve the optimal control of reactive voltage in the whole network. In practical application, it is necessary to choose the appropriate control strategy according to the specific situation and control target of the power grid. This paper also discusses the realization method of reactive voltage optimization control. These methods include real-time data acquisition and monitoring, application of optimization algorithms, delivery and execution of control instructions, etc. Through the construction of advanced automatic reactive voltage control system, the real-time monitoring and optimal control of reactive voltage can be realized, and the automation level and intelligence level of power grid can be improved. This paper summarizes the important role and application prospect of reactive voltage optimization control in power system. With the development of smart grid and the continuous progress of technology, the optimal control of reactive power and voltage will become an indispensable part of the power system. In the future, we need to continue to deeply study the theory and technology of reactive voltage optimization control to promote its wide application and development in power systems.
