Temporal and spatial tradeoffs in power system modeling with assumptions about storage: An application of the POWER model

摘要: Abstract As the number and complexity of power system planning models grows, understanding impact modeling choices on accuracy computational requirements becomes increasingly important. This study examines empirically various temporal spatial tradeoffs using POWER model for scenarios a highly renewable US system. First, common simplification representative subset hours from full year available is justified reduced form model. Accuracy losses are generally ≤6%, but storage sensitive to associated modifications, highlighting need proper balancing constraints. Cost adjustments then quantified: four resolutions (1- 8-h-average time blocks); day sizes (1 week–6 months); two site-by-site versus uniform fractional buildout across all solar wind sites; multiple extents, ranging California contiguous US. Most yield
