“…The temporal reconciliation method has been found to outperform NWP forecasts generated through 3TIER, with a FS up to 0.3. The authors in [104] proposed 'sequential reconciliation' by combining power system spatial and temporal hierarchies so that aggregate-consistent forecasts are generated both in spatial and temporal domains. Independently generated base forecasts are reconciled using two techniques: (i) forecasts are firstly reconciled in space then in time and (ii) forecasts are firstly reconciled in time then in space.…”

“…A better solution would be to produce forecasts at all hierarchical levels and suitably combine them so that the forecasts across the various aggregation levels are coherent . Combining point forecasts across different cross-sectional [1, 2, 4, 11, 12], temporal [3, 1319] as well as cross-temporal [2022] aggregation levels has been extensively studied in the literature. More recently, studies have examined the case of probabilistic and density hierarchical forecasts as opposed to point forecasts [5, 23].…”

“…The concept of reconciliation emerges when the forecast quantity, such as renewable power generation [17][18][19], electrical load [20], tourism demand [21], or FMCG demand [22], can be modeled as a hierarchy. Due to the different information sets available at various levels in the hierarchy, e.g., retailers' business strategy is opaque to the distributor, and modeling uncertainties, the lower-level forecasts almost surely do not sum up to the higher-level forecasts.…”
