Realization of power dispatching automation and control system based on smart grid

电力调度自动化中的峰值约束和各个层级间断面的潮流限制约束问题极大的降低了系统的运行速度,影响业务的正常运行,导致电力调度的效率下降。为了减缓两种约束给系统带来的弊端,本文提出了一种智能电网的电力调度自动化优化控制模型,以计算机和自动优化技术为核心,包括安全分析、状态估计、在线负荷预测、自动发电控制等功能模块,通过电网双向供电交互式系统调度,使得电力调度达到最优化状态。经过实验测试表明,在电网系统中采用本文的方法下,电力调度的效率较大提高,控制系统运行速度提高了32%,证明本文方法的有效性和可靠性。

The peak constraint in power dispatching automation and the power flow restriction constraint problem between sections of each level greatly reduce the running speed of the system,affect the normal operation of the service,and lead to the decline of the efficiency of power dispatching. In order to alleviate the shortcomings caused by the two constraints,this paper proposes a power grid automation optimization control model for smart grid,with computer and automatic optimization technology as the core,including security analysis,state estimation,online load forecasting,automatic power generation control. The functional modules are distributed through the grid bidirectional power supply interactive system,so that the power dispatching is optimized. The experimental results show that under the method of this paper,the operating speed of the control system is increased by 32%,and the efficiency of power dispatching is improved by 25%,which proves the effectiveness and reliability of the proposed method.
