This paper introduces a ANFIS power flow control of interconnected AC-DC micro-grids in grid-connected hybrid micro-grids based on implementing a modified unified interphase power controller (UIPC). A typical grid connected hybrid micro-grid including one AC micro-grid and one DC micro-grid is considered. These micro-grids are interconnected using a modified UIPC. As the first contribution of this paper, the ANFIS controller, which uses three power converters in each phase is modified so that a reduced number of power converters is implemented for power exchange control between AC-DC micro-grids. The modified structure includes one power converter in each phase, named as the line power converter (LPC). And a power converter which regulates the DC bus voltage, named as bus power converter (BPC). The AC micro-grid is connected to the main grid through the LPCs which their DC buses are linked and can operate in capacitance mode (CM) or inductive mode (IM). ANFIS controller is used in the control structure of the LPCs. The ANFIS inference system is optimized based on H filtering method to reduce the errors in membership functions design. Thus as the second contribution to stabilize the DC link fluctuation. A new nonlinear disturbance observer based robust multiple-surface sliding mode control (NDO-MS-SMC) strategy is presented for DC side control of the BPC.
