Description

Technical Field

[0001] The present invention relates to the technical field of intelligent coordinated control systems, and in particular to a generalized intelligent coordinated control system and method. Background Art

[0002] Intelligent coordinated control refers to a control method in which the subsystem that controls the load in the coordinated control system accepts the restrictions on steam pressure changes, and the subsystem that controls the steam pressure accepts instructions in advance to reflect the needs of load changes, so that the boiler and steam turbine can coordinate with each other to control power and steam pressure.

[0003] In order to increase the balance and operational stability between power generation equipment and energy storage equipment, a coordinated control system will be used to transmit the current generated by each different power generation method to the storage device for storage according to the rated power current.

[0004] Traditional coordinated control systems generally only coordinate the input and output currents, which will cause some electric energy to be wasted during the transmission process, and will also affect the system response speed, reduce the frequency modulation times and the optimization of energy storage characteristics matching, thereby reducing the overall service life of the system.

[0005] Therefore, it is necessary to provide a generalized intelligent coordinated control system and method to solve the above technical problems. Summary of the invention
