The ever-changing grid is currently shifting towards distributed generation and the implementation of a growing number of inverter-based power plants, including wind turbines, photovoltaic (PV) arrays and batteries. Due to the increasing number of installations, an increase in the occurrence of interaction problems can be expected. It also leads to a reduction in synchronous machines, which weakens the grid and increases the risk of transient voltage instability and converter instability in grid-following systems. Better controls and parameter tuning can reduce these risks, but there is a limit to how far they can go. In addition, the restoration of meshed networks is becoming increasingly important. This leads to the following challenges:
