Abstract:In order to deal with the massive, heterogeneous and distributed power data, it is urgent to use new information technology to process and manage power data in smart grid. In this paper, an efficient and secure data aggregation scheme in smart grid is proposed (ESDAS). This paper first models the distributed and hierarchical data aggregation architecture of smart grid by utilizing mathematical method. In order to find the optimal aggregator placement, a distributed cost update algorithm is also proposed. By in… Show more
