Joint Optimal PMU Placement and Data Pruning for Resource Efficient Smart Grid Monitoring

This article proposes a novel joint system-aware data pruning and optimal phasor measurement unit (PMU) placement framework for smart grid monitoring. Mathematical modeling of the spatial error propagation across the system due to distorted reconstruction of direct measurements at the phasor data concentrator is undertaken. The node-level data pruning is analyzed on a large-scale data from the PMUs on IEEE 6, 14, 30, and 57-bus system infrastructure, under conventional deployment statistics. The analysis is extended for system-level data traffic reduction, and a revised optimal PMU placement is proposed. It is observed that the joint optimal PMU placement and system-aware optimal data pruning is able to achieve up to 95% bandwidth saving per PMU data communication. With the revised optimal PMU placement, the overall system-level communication resource consumption is reduced by $\geq 32\%$, while ensuring a predefined monitoring error threshold across the grid.
