Micro electric network coordination control system based on multi-proxy technology

Abstract

The invention relates to a micro-grid coordination control system based on multi-agent technology, pertaining to the information technology field, wherein an element agent module independently controls the operation of bottom elements in the micro-grid, realizing direct control on a distributive power source, power generation, power-reserving elements and some loads; a micro-grid agent module operates in accordance with the internal dispatching of the micro-gird and manages the agents; task division and shared resource allocation among agents are solved by communication and coordination between the micro-grid agent module and an upper grid agent module, and the upper grid agent module takes charge of the coordination and dispatching in the electric market and among agents and makes the important decisions by integrating information of the micro-grid agents. A certain amount of data communication among the agent modules are kept for better ensuring rationality for decisions made by each agent. The structure and the communication method fit the complex and flexible characteristics of micro-grid distribution. The coordination control system can promote the safe and steady operation of the micro-grid as well as the generating efficiency.

Description

technical field [0001] The invention relates to a system in the field of information technology, in particular to a micro-grid coordination control system based on multi-agent technology. Background technique [0002] Microgrid is a system composed of load and micro power supply, which can provide electric energy and heat energy at the same time; its internal power supply is mainly responsible for energy conversion by power electronic devices and provides necessary control; its performance compared to the external large power grid It is a single controlled unit and can meet the user's requirements for power quality and power supply security at the same time. It includes the following main features: 1) It includes distributed power sources such as photovoltaics and wind power. 2) Equipped with an energy management system, through the control of a large number of power electronic devices, problems such as power flow and protection can be solved. 3) It is required that it can...
