Abstract

We study the meter data management systems (MDMS) with a focus on missing data handling, and propose two approaches, called Lookback-N and Sandwich-N, based on the historical data. Using a realistic dataset, we demonstrate that Lookback-N is effective for online processing, and Sandwich-N outperforms the conventional offline approach, in terms of estimation accuracy, in all test cases. The proposed approaches are simple, effective, and show promise in handling missing data for emerging smart meter data management systems.
