Primary and Secondary Control of Grid Connected Micro Grids using ANFIS Controller

The microgrid has been defined to cope with the large penetration of distributed generations (DGs). is capable operating in grid-connected mode (GC) and islanded (IS). In microgrid, (DGs) are always connected power network via inverters. Grid Connected mode, DGs commonly acts as current controlled sources retain a high grid-current quality fast dynamic response photovoltaic wind generation systems. However, this cannot work alone without voltage/frequency support from utility-grid. Islanding occurs when portion micro-grid becomes electrically isolated, yet continues be energized by isolated subsystem. islanding inverter-interfaced voltage-controlled sources. As system voltage frequency not determined utility-grid, should take care stability. Moreover, sharing guaranteed according their individual ratings avoid circulating currents among DGs. operation control existing utility networks becoming more complex due increased interconnection DG systems diverse characteristics. So paper intends address above problems come out proper strategy using ANFIS controller that could implemented for successful microgrid.
