Research on Control of Micro Grid

The micro grid is an integrated form of distributed energy resources. The interconnection of small modular generation technologies at the medium voltage (MV) and low voltage (LV) distribution levels may affect the power system performance. This type of the networks will use the best combination of control and modeling technologies to meet the specific capacity, quality and reliability. For the MG good control, it is necessary to know dynamic behavior of the system. This paper proposes a hybrid control method for the whole micro grid and a systematic control method design of micro-sources in grid-connected mode and isolated mode are analyzed.
