In this paper we consider all consistent extensions of the AdS_5 x S^5superalgebra, psu(2,2|4), to incorporate brane charges by introducing bothbosonic and fermionic (non)central extensions. We study the Inonu-Wignercontraction of the extended psu(2,2|4) under the Penrose limit to obtain themost general consistent extension of the plane-wave superalgebra and comparethese extensions with the possible BPS (flat or spherical) brane configurationsin the plane-wave background. We give an explicit realization of some of theseextensions in terms of the Tiny Graviton Matrix Theory (TGMT)[hep-th/0406214]which is the 0+1 dimensional gauge theory conjectured to describe the DLCQ ofstrings on the AdS_5 x S^5 and/or the plane-wave background.Comment: 27 pages, LaTe
