Core claim
The study presents a controlled parametric framework for analyzing energy storage planning under uncertainty in a multi-stage model predictive control setting. Through parametrized generation of synthetic datasets in energy price arbitrage, it characterizes the joint effects of battery characteristics, signal structure, forecast uncertainty, and planning horizon on operational revenue.

What carries the argument
Parametrized synthetic dataset generation within a multi-stage model predictive control model for energy price arbitrage, which maps the dependencies between battery properties, data features, uncertainty levels, and horizon performance.
Where Pith is reading between the lines
- Such mappings could support the development of adaptive algorithms that select planning horizons dynamically based on observed forecast quality.
- Battery designers might use these insights to prioritize characteristics that perform well under short-horizon constraints.
- The method offers a way to test planning strategies for new energy markets without access to proprietary data.
Load-bearing premise
The synthetic dataset generation and multi-stage model accurately reflect the real combined effects of battery characteristics, price signal structure, and forecast uncertainty.
What would settle it
Collecting data from actual battery operations in energy markets and verifying whether optimal planning horizons decrease as forecast uncertainty increases in a similar systematic manner.

This study presents a controlled parametric framework for analyzing energy storage planning under uncertainty in a multi-stage model predictive control setting. The framework enables a broad and systematic exploration through parametrized generation of synthetic datasets in the context of energy price arbitrage. It facilitates the study of the joint effects of battery characteristics, signal structure, forecast uncertainty, and planning horizon on revenue performance in energy storage optimization, which are rarely considered together. The analysis is driven by two objectives. First, it characterizes how these interacting factors influence operational revenue and its sensitivity to planning horizon selection, including economic losses caused by deviations from optimal horizons. This provides guidance on expected horizon ranges and their impact on revenue and computational cost. Second, it enables a compact parametrization of the relationships between battery properties, data characteristics, forecast uncertainty, and horizon-dependent performance, providing a basis for future modelling of optimal planning horizon length. Results show that the framework captures consistent structural dependencies across configurations and provides meaningful guidance for horizon selection under uncertainty. In particular, increasing forecast uncertainty systematically reduces the optimal planning horizon across battery types, reflecting the diminishing value of long-term information under increasingly unreliable forecasts. Comparison with real market data shows that the parametrization reproduces the main qualitative trends of optimal horizon behavior, suggesting its potential as a lightweight surrogate for more complex simulation-based analysis.

Referee Report
Summary. The paper introduces a parametric framework that uses synthetic dataset generation to systematically explore the joint effects of battery characteristics, price signal structure, forecast uncertainty, and planning horizon length on revenue in multi-stage MPC for energy price arbitrage. It reports that increasing forecast uncertainty consistently shortens the optimal planning horizon across battery types, provides guidance on horizon selection and associated revenue/computational trade-offs, and shows qualitative agreement with trends in real market data, positioning the approach as a lightweight surrogate for more complex analyses.
Significance. If the synthetic generation process accurately reflects real joint distributions, the work offers practical value for selecting planning horizons under uncertainty in battery scheduling and a compact parametrization that could support future surrogate modeling. The systematic coverage of interacting factors (rarely studied together) is a positive contribution to the energy storage optimization literature.
major comments (2)
- [Methods (synthetic data generation)] Methods section on synthetic dataset generation: the process for generating price signals, injecting forecast uncertainty, and coupling these with battery parameters is not shown to be free of confounding structure (e.g., implicit coupling of uncertainty magnitude to autocorrelation or variance). This is load-bearing for the central claim that uncertainty systematically reduces optimal horizon, because an artifact in the generation procedure could produce the reported monotonic relationship rather than reflecting real market dynamics.
- [Results and validation] Results and validation sections: the headline result and guidance for horizon selection rest on qualitative trend matching to real market data only, with no quantitative metrics (error bars, R² values, sensitivity sweeps over generation hyperparameters, or out-of-sample real-data horizon computations) reported. This weakens the claim that the framework 'reproduces the main qualitative trends' sufficiently to generalize beyond the tested configurations.
minor comments (2)
- [Methods] Notation for the multi-stage MPC formulation and uncertainty parametrization could be clarified with an explicit equation or table summarizing all free parameters and their ranges.
- [Abstract and Conclusions] The abstract states that the framework 'enables a compact parametrization' of relationships, but the main text does not detail the functional form or fitting procedure used to obtain it.

Referee: [Methods (synthetic data generation)] Methods section on synthetic dataset generation: the process for generating price signals, injecting forecast uncertainty, and coupling these with battery parameters is not shown to be free of confounding structure (e.g., implicit coupling of uncertainty magnitude to autocorrelation or variance). This is load-bearing for the central claim that uncertainty systematically reduces optimal horizon, because an artifact in the generation procedure could produce the reported monotonic relationship rather than reflecting real market dynamics.
Authors: We acknowledge the referee's concern regarding potential confounding in the synthetic generation process. The framework parametrizes price signal generation independently via controllable parameters for mean, variance, and autocorrelation structure, with forecast uncertainty introduced as additive scaled noise that does not modify the base signal statistics. To address this explicitly, we will revise the Methods section to provide the full algorithmic description of the generation procedure and include empirical verification (such as pairwise correlation analyses across uncertainty levels and signal properties) confirming independence. This addition will directly support that the observed reduction in optimal horizon with increasing uncertainty arises from the modeled dynamics rather than generation artifacts. revision: yes

Referee: [Results and validation] Results and validation sections: the headline result and guidance for horizon selection rest on qualitative trend matching to real market data only, with no quantitative metrics (error bars, R² values, sensitivity sweeps over generation hyperparameters, or out-of-sample real-data horizon computations) reported. This weakens the claim that the framework 'reproduces the main qualitative trends' sufficiently to generalize beyond the tested configurations.
Authors: We agree that incorporating quantitative metrics would provide stronger validation for the generalization claims. The manuscript prioritizes qualitative trend matching to illustrate the framework's utility in capturing directional behaviors across configurations. In the revision, we will augment the Results and validation sections with error bars on key plots, R² values quantifying the uncertainty-horizon relationship, sensitivity sweeps over generation hyperparameters to demonstrate robustness, and additional out-of-sample horizon computations on real market data. These changes will offer a more rigorous quantitative foundation while preserving the focus on practical guidance. revision: yes
Circularity Check
No significant circularity; simulation results are independent of inputs
full rationale
The paper conducts a forward simulation study using parametrized synthetic price signals, injected forecast uncertainty, and multi-stage MPC optimization to map performance across battery designs, uncertainty levels, and horizons. Key observations (e.g., uncertainty shortening optimal horizons) are outputs of these numerical experiments rather than algebraic identities or parameters fitted to the target quantities and then relabeled as predictions. No equations reduce to their own inputs by construction, no load-bearing self-citations close the argument, and the qualitative match to real market data is presented as external corroboration rather than internal validation. The framework therefore remains self-contained against its own generation process.
