Efficient authentication scheme for data aggregation in smart grid with fault tolerance and fault diagnosis

Authentication schemes relying on per-packet signature and per-signature verification introduce heavy cost for computation and communication. Due to its constraint resources. smart grid’s authentication requirement cannot be satisfied by this scheme. Most importantly. it is a must to underscore smart grid’s demand for high availability. In this paper. we present …

A New Digital Distance Relaying Scheme for Series-Compensated Double-Circuit Line During Open Conductor and Ground Fault

A new digital distance relaying scheme presented in this paper provides adequate protection to series-compensated double-circuit lines during a simultaneous open conductor and ground fault. The proposed scheme is based on the derivation of the compensated values of impedance using the symmetrical components theory. It measures the correct value of …
