Query: Enhancing the Spatio-temporal Observability of Grid-Edge Resources in
  Distribution Grids   Enhancing the spatio-temporal observability of distributed energy resources
(DERs) is crucial for achieving secure and efficient operations in distribution
grids. This paper puts forth a joint recovery framework for residential loads
by leveraging the complimentary strengths of heterogeneous measurements in real
time. The proposed framework integrates low-resolution smart meter data
collected at every load node with fast-sampled feeder-level measurements from
limited number of distribution phasor measurement units. To address the lack of
data, we exploit two key characteristics for the loads and DERs, namely the
sparse changes due to infrequent activities of appliances and electric vehicles
(EVs) and the locational dependence of solar photovoltaic (PV) generation.
Accordingly, meaningful regularization terms are introduced to cast a convex
load recovery problem, which will be further simplified to reduce the
computational complexity. The load recovery solutions can be utilized to
identify the EV charging events at each load node and to infer the total
behind-the-meter PV output. Numerical tests using real-world data have
demonstrated the effectiveness of the proposed approaches in enhancing the
visibility of grid-edge DERs.
