Abstract

The invention discloses an intelligent microgrid operation and maintenance controller, comprising a concentration unit and a dispersion unit, wherein the dispersion unit cooperates with a local measurement control unit, acquires a running state of a microgrid and uploads the acquired data to the concentration unit of the intelligent microgrid operation and maintenance controller, and intelligent operation and maintenance is carried out by cooperating with the concentration unit; and the concentration unit collects the acquired data sent upward by the dispersion unit, analyzes the data and responds to user requirements, and coordination control on each unit in the microgrid according to operation strategy requirements, thus intelligent operation and maintenance on the microgrid is realized.The intelligent microgrid operation and maintenance controller provided by the invention can realize real-time high-precision measurement on the running state of the microgrid, provides a microgrid operation and maintenance strategy based on microgrid operation reliability, operation and maintenance suggestions are provided for microgrid operation and maintenance personnel, and operation and maintenance difficulty and operation and maintenance cost are reduced.

Description

technical field [0001] The invention relates to micro-grid operation and maintenance technology, in particular to a micro-grid intelligent operation and maintenance controller. Background technique [0002] Energy and environmental issues are the focus of attention of countries all over the world. In my country, in order to achieve the national goal of "energy saving and emission reduction", the power industry has vigorously developed various renewable energy power generation on the power generation side, moving towards the direction of "low carbonization" and "zero emission" of electric energy production, which has led to wind power The rapid development of distributed power sources such as power generation and photovoltaic power generation and micro-grids. Microgrid refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, related loads, monitoring and protection devices. It is an au...
