DisTT Use Case
Disaggregation of net metered distributed generation (DG) from customer load uses high-precision measurements on the utility side of the meter to estimate the actual generation and amount of load offset behind the meter.
When the distribution utility lacks access to separate load and generation telemetry from customer premises, net metered solar generation masks an unknown amount of load. This masked load implies a greater system exposure to contingencies. The masked load must be accounted for to assure adequate generation reserves in case of simultaneous tripping of many DG units, and to assure safe cold load pickup after an outage.
