This paper proposes a developed control technique for integration of renewable energy sources into the weak grids. The developed controller alleviates the negative impact of weak grid operating condition on the stability of interface converters by mean of impedance reshaping technique. Furthermore, the proposed controller provides virtual inertia to support the power grid stability. Satisfactory and stable operation of the interface converter as well as providing virtual inertia under weak grid condition with high penetration level of RESs, are the main contributions of this paper. Comparative simulation results are presented to demonstrate and verify the effectiveness of the proposed control technique.
