Summary:The paper discusses the challenges with today's power systems with large integration of renewables and the importance of short circuit contribution and inertia. Another aspect of the paper is to highlight impact on power quality devices (SVC, STATCOM, HVDC, MSC, harmonic filters etc.) when system parameters such as harmonic resonances and SCR is changing.The falling fault levels on system may require Synchronous Condensers to be installed which enhance inertia, dynamic performance and improves stability of the grid. A hybrid configuration based on STATCOM and Synchronous Condenser technologies is discussed as a solution there each technology focus on their best characteristic to optimize power system performance. Low SCR impact on SVC and STATCOM performance is also highlighted. Simulations with STATCOM and Synchronous Condenser in same connection point is presented to show contribution to fault ride through. The importance of common and coordinated control of the devices to achieve optimum performance, and the advantage of overload capacity of Synchronous Condenser in conjunction with fault handling is shown in simulation result.
