Dynamic Characteristics-Based Capacity Optimization Strategy for Hybrid AA-CAES and Battery Storage Systems in Source-Grid-Load-Storage Integrated Base
Bibliographic record
Abstract
Advanced adiabatic compressed air energy storage (AA-CAES) is a promising large-scale energy storage technology, offering a long lifespan, low maintenance, and high safety. However, its slower response speed limits its ability to handle the rapid fluctuations of wind and solar power. Combining AA-CAES with battery storage in a hybrid system provides an optimal solution for integrated energy bases, prompting the need for robust capacity planning. Existing AA-CAES planning strategies, developed primarily for grid-connected applications, often neglect AA-CAES’s dynamic characteristics, making them unsuitable for hybrid contexts. To address this issue, this paper proposes a capacity optimization strategy that incorporates AA-CAES’s dynamic behavior into a cost-minimization model with operational constraints. Using historical wind, solar, and load data, the proposed approach is compared with conventional battery-only configurations. The case study demonstrates that the proposed CAES-Li hybrid energy storage system achieves 30-45% annualized cost reductions compared to traditional Li-ES configurations, with sensitivity analyses revealing critical optimization pathways through efficiency enhancements and technology cost reductions.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
