An improved decentralized multi-agent system for multi-objective energy management in microgrids

Abstract

The invention discloses an improved distributed multi-agent system that can be used for micro-grid multi-target energy management, including: at least one micro-grid unit; a main container, which includes a basic Agent, an aggregated electrical Agent and an Agent platform; the basic Agent is used for Making decisions, negotiating and executing microgrid unit solutions, its running time is defined as the decision cycle, which starts asynchronously with unpredictable events, and the completion time is dynamically adjusted; the basic Agent also includes an allocation unit, and the microgrid units are divided according to functions , and the allocation unit is paired with at least one type of basic Agent; at least one Agent container, each Agent container includes a unit electrical Agent and at least one basic Agent, the unit electrical Agent is bound to a microgrid unit, and sends the corresponding electrical information to Aggregate electrical Agent; each basic Agent communicates with Agent protocol. Establish communication among agents, make decisions on their own behavior based on their own information and local environmental information, and finally achieve the overall optimization control goal of the microgrid.

Description

technical field [0001] The invention relates to the technical field of microgrid energy management and control, in particular to an improved distributed multi-agent system that can be used for microgrid multi-target energy management. Background technique [0002] In recent years, in view of the outstanding problems in distributed power generation and microgrid operation control and optimization, various artificial intelligence technologies such as Multi Agent System (MAS) technology, genetic algorithm, artificial neural network, fuzzy logic, etc. have been applied to distributed power generation. and the field of microgrid control have received extensive attention. [0003] The definition of MAS is a collection of autonomous computing entities (Agents), which can be effectively applied to perform tasks based on goals in environments that are difficult to define and analyze. The operation of each microgrid unit in the microgrid has relatively strong independence and must ha...
