Distributed power supply voltage control method based on hybrid layered multi-agent system

Abstract

The invention provides a distributed power supply voltage control method based on a hybrid layered multi-agent system. The method comprises the following steps that: (1) the hybrid layered multi-agent system is constructed; (2) distributed power supply cluster agents obtain voltage maximum and minimum values of each line; (3) a trend model is simplified; and (4) the voltage of a line node is judged, if the voltage of the node is lower than a voltage limit value, boosting is carried out, and if the voltage of the node is higher than the voltage limit value, then voltage reduction is carried out. According to the invention, the task load of a single Agent is reduced, the calculation time is shortened, the algorithm is simplified, the amount of communication data is reduced, and the communication time is shortened; in addition, a communication line is annularly designed, communication lines are added as few as possible, and the reliability of the system is simultaneously improved.

Description

technical field [0001] The invention relates to a distributed power supply voltage control method, in particular to a distributed power supply voltage control method based on a hybrid layered multi-agent system. 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. 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 metho...

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
