Dynamic Linkages between VRE Cost and Penetration Rate in Future Energy System Fudan University, China, People's Republic of The rapid expansion of variable renewable energy (VRE) is reshaping power-system economics: as penetration rises, investment costs often fall through learning-by-doing, while integration costs may increase due to balancing, network, and adequacy needs. This study synthesizes evidence on this penetration–cost co-evolution and assesses how cost representations in planning and dispatch models affect inferred cost-optimal VRE shares. We summarize empirical and model-based learning effects for wind and solar and review integration-cost definitions, components, and quantification methods, showing that estimates diverge widely with system boundaries, allocation rules, and assumed flexibility. Comparing common model formulations, we find that incomplete treatment of learning and integration costs can bias long-term system design, typically underestimating system costs at high penetration and distorting cost-optimal VRE shares. Key modeling priorities and research gaps are highlighted for representing learning and integration costs consistently, thereby improving the robustness of VRE-oriented planning results. | |
