Intelligent control system for microgrid

Abstract

The invention discloses an intelligent control system for a microgrid. The intelligent control system for the microgrid comprises a microgrid energy management unit, a central control unit and a distribution type control unit, wherein the central control unit is respectively connected with the microgrid energy management unit and the distribution type control unit; the microgrid energy management unit is used for realizing the optimal energy matching of the mcrogid; the central control unit issues a command to the distribution type control unit according to the comprehensive operation control command of the microgrid energy management unit; and the distribution type control unit controls a power generation unit or an energy storage device. According to the intelligent control system for the microgrid, which is disclosed by the invention, the whole system is divided into different logic blocks, a system function is refined, and the system development and maintenance cost is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of microgrid control systems, in particular to a microgrid intelligent control system. Background technique [0002] Since the beginning of the 21st century, with the continuous decline of oil, coal and other resource reserves, the world's energy supply has continued to be tense, and the development and utilization of clean and efficient renewable energy has become the main way to solve future energy problems. Several new energy sources that are currently widely used include solar energy, wind energy, fuel cells, etc., all of which are distributed energy resources (DER), and some corresponding power generation technologies are called distributed generation technology (Distributed Generation, DG). Combining distributed power generation technology with large power grids is considered by many experts and scholars at home and abroad to be the main way to reduce energy consumption and improve the security and fle...
