Power grid linkage type stable sectional power flow control method and server

Abstract

The invention discloses a power grid linkage type stable sectional power flow control method and a server. The power flow control method comprises the following steps of judging whether each stable section is out of limit or not according to power flow and a control zone of each stable section in a power grid linkage type stable sectional set; adjusting the output of a correlated control machine set so as to carry out upper limit control on the stable section exceeding an upper limit in the linkage type stable sectional set according to adjusted associated information between an upper-stage stable section and a lower-stage stable section in the linkage type stable sectional set when the stable section exceeds the upper limit; adjusting the output of the correlated control machine set so as to carry out lower limit control on the stable section exceeding a lower limit in the linkage type stable sectional set according to the adjusted associated information between the upper-stage stable section and the lower-stage stable section in the linkage type stable sectional set when the stable section exceeds the lower limit; and counting total adjustment quantity of all participated linkage type stable sectional power flow control machine sets, and updating the control adjustment quantity of an automatic generation control (AGC) region.

Description

technical field [0001] The invention relates to an electric power system scheduling automation technology, in particular to a power grid chain-type stable section power flow control method and a server. Background technique [0002] Power dispatching is a key link to ensure the safe, high-quality, economical and environmentally friendly operation of the power grid. As a technical support system for power dispatching, the power dispatching automation system is the brain and command center of the power system operation. [0003] Dispatchers in the power dispatching center rely on various information and functions provided by the power dispatching automation system to conduct daily dispatching of the power system. Among them, the monitoring and control of the stable section of the power grid is an important task. However, the existing power dispatching automation system provides relatively limited technical support for dispatching operation, which is manifested in the fact that...

Problems solved by technology

However, the existing power dispatching automation system provides relatively limited technical support for dispatching operation, which is manifested in the fact that the stable section of the power grid currently only has a monitoring function, and the control of the flow of the stable section can only be done manually

With the continuous expansion of the grid scale, the increasingly complex grid structure and the complex and changeable grid operation mode, it has become more and more difficult to control the stable section of the grid manually, and it is difficult to meet the real-time requirements. The daily dispatch of personnel and the safe and stable operation of the power grid have brought new challenges
