Abstract

The invention provides a test method and system for a micro grid energy management system. The test method comprises the steps that a micro grid model is built on an RT-LAB real-time simulation host;the micro grid model comprises at least one renewable energy power supply device model, at least one energy storage device model and a micro grid communication interface; the renewable energy power supply device model and the energy storage device model are connected with the micro grid communication interface respectively; the simulation host compiles and downloads the micro grid model to a real-time target machine; the real-time target machine runs the micro grid model, acquires the status information of a micro grid in real time, and uploads the information to the simulation host; the status information of the micro grid is uploaded to the micro grid energy management system through the micro grid communication interface; a dispatch instruction sent by the micro grid energy management system is received through the micro grid communication interface; and the dispatch instruction is issued to the real-time target machine for execution. The test method and system have the advantages of low cost, convenient realization, comprehensive problem testing and good real-time performance.

Description

technical field [0001] The invention relates to the field of real-time simulation testing of power systems, in particular to a testing method and system for a microgrid energy management system. Background technique [0002] With the depletion of petrochemical energy and the rapid development of new energy power generation, green energy represented by distributed microgrids has gradually attracted people's attention. Compared with traditional fossil fuel power generation technologies, the power generated by distributed microgrids is often random and cannot Directly put into use, the micro-grid energy management system is the key technology to realize the distributed micro-grid for people to use. Equipped with the micro-grid energy management system, the distributed micro-grid becomes intelligent, efficient, economical and environmentally friendly; As the core of the flexible operation of the microgrid system, it is very important to test the microgrid energy management algor...
