Abstract

The invention belongs to the technical field of power systems and automation of the power systems, and discloses an emergency control optimization method of an electrolytic aluminum self-prepared power grid and based on transient state safety and stability. According to the method, safety and economy are combined, the method is used for making transient safety and stability control measures of the electrolytic aluminum self-prepared power grid, and reference is provided for safety and stability optimization control of an electrolytic aluminum production power supply system through time domain simulation and control cost function establishment.

Description

technical field [0001] The invention belongs to the technical field of electric power systems and automation thereof, and in particular relates to an emergency control optimization method for an electrolytic aluminum self-contained power grid based on transient safety and stability. Background technique [0002] In recent years, with the rapid development of the economy, high energy-consuming industries such as electrolytic aluminum have developed rapidly. Due to the constraints of economic and policy factors, many enterprises have built their own power plants to supply power to their loads. The electrolytic aluminum load belongs to the first-class important load, and has extremely high requirements on the reliability of power supply. The safe and stable operation of electrolytic aluminum power supply system is very important. [0003] The electrolytic aluminum self-contained power grid has its remarkable characteristics. If its security and stability control is completely...
