The method provided by the invention is applied to optimization of the controller parameters of the automatic power grid generation control system.

Description

technical field [0001] The invention relates to the field of automatic control of power systems, in particular to a parameter optimization method for a controller of a power grid automatic generation control system. Background technique [0002] Frequency is one of the most important parameters in power system operation, which reflects the real-time balance state of the active power of the system. Controlling the system frequency is a content that cannot be ignored in the safe operation of the power system. In order to maintain the frequency deviation during system operation within the allowable range, modern power grids mainly use Automatic Generation Control (AGC) technology to continuously change the active output of frequency modulation units to balance random load fluctuations. Among them, the controller The parameters have an important impact on the dynamic control performance of the grid automatic generation control system. [0003] As a mature control technology, f...
