High voltage direct current (HVDC) links are increasingly used for asynchronous interconnection of AC systems apart from long distance bulk power transmission. The interconnection through HVDC links are generally characterized by weak AC systems. The relative strength of the AC system at the point of coupling is measured by short circuit ratio (SCR) which is defined as the equivalent admittance of the AC system on the base of DC power rating. The AC system is considered to be weak when SCR is less than three.
