Abstract : —Integrated communications with sensing and measurements are relevant technologies identified to pro-vide automation for the smart grid SG applications. Incorporating intelligence into the electrical grid neces-sitates the gathering of relevant information in in real-time from variety of electrical utility sources located either at the bulk generation, transmission, distribution or customer domain. The deployment of wireless sensor network WSN is an attractive solution for such task, due to certain merits. In this paper, we show how large WSN cluster could benefit from distributed max-dmin MIMO precoder with a proposed node selection technique offering a realistic implementation. We exploit spatial diversity of the nodes to make the channel state information CSI available at transmitting nodes organized into a cluster. Performance evaluation of the nodes selection technique shows substantial amount of energy can be saved in high voltage HV power substation channel environment that is corrupted by Additive White Gaussian Noise AWGN, impulsive noise, and node synchronization errors.
