Description

Method and device for optimally regulating and controlling flexible load resources, storage medium and processor

At present, the flexible load control technical modes at home and abroad mainly comprise: centralized control system, distributed control system, and distributed control system. The centralized control structure frame is to establish a bidirectional communication channel between a unified control center and all controlled loads. The control center directly gives control instructions to each load device, and the load devices respond accordingly and upload the running state information of the devices to the control center. The application representative of centralized control architecture is direct load control (Direct Load Control, DLC), which is often suitable for large industrial users with relatively centralized loads. The realization of the distributed control mode requires that each load device corresponds to an independent controller, the load devices automatically respond according to the frequency information detected by the controller, the information interaction with a power grid dispatching center is not required, and the load devices are isolated from each other. The distributed control scheme requires the addition of a load manager, i.e., a load aggregator, as an intermediary for information transfer between the individual load controllers and the dispatch control center over the distributed control scheme. On the one hand, the load aggregator aggregates the running state information of the controlled load and then uploads the running state information to the control center, and meanwhile, receives and analyzes the instruction of the control center and then transmits the instruction to the load equipment.
However, the current flexible load regulation and control technology of the power grid regulates and controls the load according to the flexible load timing and quantifying of the protocol user, meets the peak clipping requirement of the power grid at different periods, and directly or indirectly reduces the flexible load so as to cause the user to generate unfavorable perception or inconvenience of electricity consumption. Meanwhile, the flexible load regulation and control technology is more load peak clipping, and a control method for improving the new energy absorbing capacity by increasing the load demand of a user is not considered.
Aiming at the problem that the flexible load regulation technology in the related technology does not consider improving the new energy consumption capability by increasing the load demand of a user, no effective solution is proposed at present.
