False data injection (FDI) attack is one of the severe attacks that threatens the smart grid's efficiency and reliability. Power grid's status is monitored by many measurement units spread all over the grid; these units periodically send their measurements to the grid's control center (CC), which utilizes them to make the right decisions for the grid. FDI attack inserts fake measurements among the...
To reduce the huge consumption of traditional sensing, a multi-centers estimation based sensing scheme is proposed in this paper. Firstly, all potential channels are clustered into highly related groups with some channels selected as detecting channels (DCs) using an unsupervised algorithm. In each group, the states of other channels (estimated channels, ECs) are estimated according to their correlations...
