Data Buffering for Interrupted Energy Metering
The ongoing project compares two buffering strategies for measurement series that contain gaps, duplicates or misplaced values after offline phases.
Problem
Measurement series contain gaps, duplicates or misplaced values after offline phases. How well a series can be reconstructed afterwards depends on what is kept locally and how it is retransmitted.
Research question
How do local buffering and retransmission differ when storage is limited? The question concerns the conditions under which one strategy preserves the series better than the other.
Method
The work uses synthetic time series, controlled interruption windows and two buffering strategies. The experiments take place on the network test bench.
Evaluation criteria
Completeness, duplicate rate, temporal assignment and storage requirements are assessed. No measurement figures exist at present, and none are anticipated here.
Expected outcome
A traceable scenario and edge cases for storage utilisation are expected. The project is ongoing; reliable results are still outstanding.
Limits
The project does not examine productive smart-meter operation and uses no personal consumption data.
