Micro grid is an important puzzle of the energy Internet. As the brain of the integrated energy station

the coordination controller assumes the pivotal role of control and command.Firstly

in order to verify the performance of the coordinated controller of the micro grid

the typical elements and networking schemes of the micro grid are firstly introduced. Secondly

microgrid simulation system containing all elements is built based on the RTDS real-time simulation platform. Next

the communication networking scheme between the coordinated controller and the RTDS is designed. Finally

simulation tests are carried out based on the closed loop test system

including one - button start - stop test

frequency modulation test

and backup power supply test. The simulation results verify the functions of the coordinated controller

and can provide a solid guarantee for the subsequent application of the coordinated controller on the project site.
