Validation is the first step in the VEEValidation, Estimation, Editing - systematic process to ensure quality of raw metering data from electricity meters. (Validation, EstimationThe second step in VEE - calculation of missing or rejected metering values based on historical patterns, neighbouring meters or statistical models., EditingThe third step in VEE - manual correction of metering values that cannot be resolved automatically, with full audit trail for all changes.) process. Its purpose is to identify metering values that are obviously erroneous - such as negative consumption, extreme jumps between intervals, missing readings or values outside technically possible ranges. Validation runs automatically in MDMMeter Data Management - system for collection, storage, quality assurance and distribution of metering data from the electricity grid. systems based on configurable rules. Readings that fail validation are flagged and passed to estimation or manual editing. Robust validation is the cornerstone of data qualityThe degree of accuracy, completeness and reliability in a dataset - critical for correct billing and balance settlement in the power sector. work and determines whether metering dataData from electricity meters - the foundation for billing, balance settlement and market processes in the power market. are reliable enough for billing and balance settlementFinancial settlement between BRPs and the system operator for energy imbalances in a given period..
