Background technique [0002] With the development of distributed power generation technology, there are more and more applications of distributed power generation. Regional control and network control have become the main control methods under the condition of high penetration distributed power generation access. Distributed power clusters control a certain number of power sources with similar output characteristics and close geographical locations, and present a distributed power regional control system with a single controllable interface to the outside world.

AI Technical Summary

Problems solved by technology

Due to the distributed nature of distributed power clusters and a large amount of control data, the control of distributed power clusters is relatively difficult. The traditional centralized scheduling method requires a large amount of data communication, and it is difficult to achieve flexible and effective control.

With the development of smart grid, intelligent agent (agent) is gradually applied in distributed power clusters to adapt to the operation mode of distributed power clusters. However, due to the limited computing power of Agents, traditional centralized control methods are still unable to effectively implement Flexible control, and a large amount of communication data increases the communication time

Most of the existing multi-agent system voltage control adopts centralized control, ignoring the calculation function of the underlying Agent, and concentrating the calculation and control tasks on the upper Agent, which results in a large amount of data communication and long communication time.

Moreover, the calculation tasks are concentrated, which greatly increases the calculation amount of the upper agent and takes a long time to calculate.

Since the computing power of other agents is not considered, intelligent resources are not fully utilized

At the same time, when a communication line of the system fails, the control equipment connected to it cannot send and receive information, and the reliability is not high.
