| Abstract: |
| Operating characteristics of high permeability distributed generator (DG) in micro-grid (MG) is analyzed firstly, and special operation problems of distribution network brought about high permeability DG in MG is also described, on this basis, the multi time scale MG stable control method based on the design of three layer control architecture is proposed. This method is composed of four aspects, including the fast stable control by MG power electronics equipment, transient stable control of MG, dynamic stable control of MG and steady state stable control of MG. This method can complete power rapid adjustment, disturbance quickly stabilization, fault rapid isolation, operation efficiency improvement, and stable level optimization. This paper focuses on the research of realization method of fast stable control which is participated by power electronic equipment. Related engineering applications show that the above method is effective. |
