On the Calculation of Time Alignment Errors in Data Management Platforms for Distribution Grid Data
Sensors, 2021 The operation and planning of distribution grids require the joint processing of measurements from different grid locations. Since measurement devices in low- and medium-voltage grids lack precise clock synchronization, it is important for data ...
