Multi-agent optimized coordination control method of electric network

Abstract

The invention relates to a multi-agent optimized coordination control method of an electric network in the technical field of electric networks, which comprises the following steps of: collecting local electric information, transmitting the local electric information to a central agent of a microgrid and issuing a control command by a local electric network to the central agent of the microgrid simultaneously; computing by a grid technology; issuing a new control command by the central agent of the microgrid and transmitting the information to a regulation agent of the local electric network by a network line simultaneously; receiving a dispatching instruction of the central agent of the microgrid by the agent of each element and carrying out logical judgment on a result executing these dispatching commands according to the collected local electric information; and meanwhile, optimizing the electric network within a control range by the regulation agent of the local electric network and controlling a computer to carry out parallel computation by the grid technology. The invention is suitable for carrying out optimal dispatching on a distributed energy resource of an intelligent electric network, can control each power supply by an optimization scheme, also enhances the operational processing time greatly and ensures that the intelligent electric network runs safely, stably andeconomically.

Description

technical field [0001] The invention relates to a control method in the field of power grid technology, in particular to a multi-agent optimization coordination control method for a power grid based on grid technology. Background technique [0002] In the future smart grid, electric energy not only flows from the centralized power plant to the transmission grid, distribution network and even to the user, but also various forms of new and clean energy are distributed in the grid, including: solar energy, wind energy, fuel cells, electric vehicles Wait, when these energy sources are installed at the user's end, they are called distributed energy sources. However, when a large number of distributed energy sources are integrated into the grid, the complexity of the grid structure, energy form, power flow, information exchange and control methods will increase greatly. Therefore, how to intelligently manage various distributed energy sources is one of the key technologies to rea...

[0005] After searching the existing technical documents, it is found that Chinese patent application number 200710152493.0, title of invention: system and method for controlling microgrid, publication number: CN101207284, this patent better realizes the connection between large grid and microgrid through the connecting line controller control and management, but this method: (1) the control method lacks the optimization analysis and fast calculation method for the operation of the whole network; (2) the control method does not consider the error correction of the wrong command, which may cause the possibility of system instability. It is difficult for the connected line controller to achieve real-time control due to network delay or congestion, and it is difficult to achieve the purpose of economical and stable operation of the power grid
