The work – IPMI based protocol for smart grid architecture (named as SGMPI) aims to define and develop a Software System Architecture (SSA) for power grid electronics. The ability of the electronics to communicate with each other and use feedback makes the Power Grid a Smart Grid. The software system running on the embedded electronics in the power grid, reside at the various generating sources, substations and distribution points. The huge volume of data collected from these points, has to be managed and the methodology of data server architecture is a promising solution. Smart grid architecture demands remote-data monitoring and robust data exchange. IPMI based architecture is capable of handling the large amounts of static data and short bursts of dynamic data in the grid. Proposed architectural solution is described in “4+1 architectural model” and arrive a detailed architectural viewpoint. The methodology of deriving IPMI architecture for smart grid is explained. In short, new data oriented software architecture for smart grid system is explored. © 2020, World Academy of Research in Science and Engineering. All rights reserved.
