The integrated operation of the microgrid with assistance from the utility grid provides both
continuous power availability and electrification of the rural areas. The application of Renewable energy sources,
such as wind and solar photovoltaic (PV) arrays, support the grid and lower electricity costs. In this paper, a dual
mode transfer scheme is used, which allows the control to switch from the present control mode to an
independent functioning mode in the event of a power outage or grid failure. The signal sent to the static transfer
switches (STS) determines when the operational modes begin. Reducing the renewable intermittent nature of
wind and solar PV arrays is made possible in large part by the microgrid's energy storage and grid link. Then By
regulating local load support, the improvement in power quality (PQ) as well as energy security and sufficiency
are perceived. In the grid-connected mode of operation, or current control, the bias compensated improved affine
projection like (BC-IAPL) adaptive filter is used; in the standalone mode, or voltage control, the modified
proportional resonant (MPR) controller is aided by dual modified generalized integrator-based phase locked loop
(DMGI-PLL). The cost of mechanical sensors is decreased by using a modified sensor less technique to estimate
the wind generator's speed and rotor position. A detailed understanding of the microgrid's cooperative behavior
is established.
