Research On Control Strategy Of The Micro-grid With Different Types Of Distributed Sources

This article to control Micro-Grid method is the focus of research,first introduced the definition of distributed gend Micro-Grid,followed by a simple study of the four common mathematical model of distneration aributed power.It focuses on distributed power control method based on grid inverter,generator virtual method microgrid control and microgrid control method based on the in vitro and network and network operation mode control mode micro-grid were in-depth discussion.Last created based on the P/Q control and V/f control,micro-grid model,shaped in the mold as a large power inverter interfaces Interface with DG,rely on this way to control and verify the P/Q V/f control in MATLAB / SIMULINK Simulation Software the way.On the one hand under the V/f control micro-grid and network operation,and the two run off-grid mode switch each other,then the simulation analysis using MATLAB / SIMULINK,then control strategy based on a peer to peer micro-grid and off-grid network run each other conversion of these two modes of simulation,to arrive at an important conclusion is based on the following method of controlling a virtual micro-grid generators microgrid grid,off-grid conversion between these two modes and the simulation analysis.By running the simulation feature micro-grid switching between each other and off-grid and grid-connected and off-grid reliability and accuracy.
