Model order reduction (MOR) has been widely used in the electric networks but little has been done to reduce higher index differential algebraic equations(DAEs). Most methods first do an index reduction before reducing a higher DAEs but this can lead to loss of system physical properties. In this paper we present a new MOR method for DAEs called the index-aware MOR (IMOR) which can reduce higher index-2 system while preserving the index of the system.
