This article proposes a "cross-forming" control concept for grid-forming inverters operating against grid faults. . Proposing an unbalanced current limiting strategy is the main aim to be achieved in this paper. It differs from classical grid-forming and grid-following paradigms that feature voltage magnitude-and-angle. . The primary focus is on understanding the implications of the current limiter on the overall system performance and developing methodologies to mitigate any adverse effects on the outer control loops. Through simulation results, the effectiveness of these strategies in protecting inverters under. .
