Estimation is the second step in the VEEValidation, Estimation, Editing - systematic process to ensure quality of raw metering data from electricity meters. (ValidationThe first step in VEE - automated checks of metering data against technical and logical limits to detect obviously erroneous values., Estimation, EditingThe third step in VEE - manual correction of metering values that cannot be resolved automatically, with full audit trail for all changes.) process. When a meter reading is missing or has been rejected by validation, the MDMMeter Data Management - system for collection, storage, quality assurance and distribution of metering data from the electricity grid. system calculates a substitute value. Common estimation methods include using historical averages for the relevant hour and weekday, interpolation between known values, and data from neighbouring meters in the same grid area. Estimated values are clearly flagged so they can be distinguished from actual readings. Good estimation ensures the metering dataData from electricity meters - the foundation for billing, balance settlement and market processes in the power market. series is complete and usable for billing and balance settlementFinancial settlement between BRPs and the system operator for energy imbalances in a given period. even during communication failures or meter faults.
