Energy local area network distributed cooperative control method based on multi-intelligent-agent system

Abstract

The invention discloses an energy local area network distributed cooperative control method based on a multi-intelligent-agent system. The method comprises the following steps: (1) constructing a three-level control framework of the energy local area network, namely a control framework of local droop control-secondary power optimization control-centralized optimization and area autonomous control;(2) designing a dispatching decision function module, in the processes of fault generator tripping and connection and disconnection switching in the energy local area network, coordinating the controllable resources with different control response rates, responding to the internal and external energy requirements of the local area network, and rapidly stabilizing the power fluctuation of the interconnection line; (3) constructing a distributed sparse communication network based on a multi-intelligent-agent system, communicating through the adjacent intelligent agents, estimating the average voltage of the whole net based on the consistency algorithm, and correcting the voltage and the frequency of the local droop controller to simulate the behavior of the synchronous generator. The control method provided realizes the energy management optimization, flexible interaction of multiple users, and coordinate operation of distributed resources.

Description

technical field [0001] The invention relates to the field of distributed cooperative control of an energy local area network, in particular to a method for distributed cooperative control of an energy local area network based on a multi-agent system. Background technique [0002] With the substantial increase of the proportion of renewable energy in the power grid, random fluctuations of distributed power sources and loads pose a great challenge to the operation security of the power grid. Because the energy local area network can flexibly and reliably combine distributed power sources, loads, energy storage and control devices, and seamlessly connect to large power grids, it has attracted more and more attention in recent years. [0003] In terms of energy local area network energy management system research and construction, the European Power Matching City project proposes to realize coordinated interconnection of energy supply and thermal power demand based on multi-agen...
