N2 - Grid interfaced converter (GIC) is a crucial element in microgrids for efficient utilization of the generated electrical energy. The microgrid plants are situated in far distances from the load centers, which are eventually integrated into weak utility grid. Therefore, synchronization and efficient power flow together with improved quality become the fundamental criteria when choosing a control strategy. This paper proposes a multi-generalized integrator-based control strategy to improve the power transfer capabilities of a weak grid interfaced microgrid. The vital parameters considered here are, dc-offset rejection, power quality, and unity power factor operation under various modes of microgrid operation. All theoretical implications of the proposed controller are examined through numerical simulations by testing the controller for various conditions of grid, load, and microgrid operations. The simulation results substantiate the efficacy of the proposed controller during the adverse conditions of the utility grid and increased power flow from microgrid sources.
