Intelligent microgrid power-supply system

Abstract

The invention relates to an intelligent microgrid power-supply system which is formed by a power distribution cabinet special for a microgrid, an energy management system, a distributed power source loop, a load loop, an energy storage loop and an active filtering loop. The intelligent microgrid power-supply system achieves diversified application of a novel power source and a novel load in an intelligent building power-supply system, the problem of negative influence of complexity of the building power-supply system on a power distribution system is solved, and novel intelligent building power supply can be accepted by a large power distribution system. By control of the energy management system, multifunctional innovation of the power distribution cabinet special for the microgrid, reasonable coordinating operation of the distributed power source loop and the energy storage loop and peak valley electrovalence adjustment, the intelligent microgrid power-supply system achieves the aims of the demand side response load adjustment and peak clipping and valley filling of a distributed power source, and the running of the microgrid is safe and reliable through conversion of grid connection and an islanding mode.

Description

technical field [0001] The invention belongs to the fields of power supply, power distribution, power utilization and electrification, and specifically relates to an intelligent micro-grid power supply system. Background technique [0002] With the rapid development of building electrical system technology, the power loads of buildings are becoming more and more diverse, and clean energy such as photovoltaic power generation and wind power generation for energy saving and consumption reduction are gradually widely used in buildings and buildings. The operation has had an extremely negative impact. At present, there is no power supply system for the characteristics of the microgrid. The application of the traditional power supply system makes the operation mode and system control difficult. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the existing technology, aiming at the special requirements of micro-grid power...
