Smoothing Out the Sun's Wrinkles: A New Filter for Solar Power, But is it a Game Changer?
This paper investigates the use of Savitzky-Golay filtering combined with battery energy storage to smooth solar power fluctuations and reduce ramp rates. The results suggest that this method can achieve good smoothing performance with less battery usage compared to moving average, low-pass, and Gaussian filters, but further analysis with more datasets and cost considerations is needed.
Possible Conflicts of Interest
This work was supported in part by the Deanship of Research with the King Fahd University of Petroleum and Minerals and the King Abdullah City for Atomic and Renewable Energy (K.A.CARE). While these are academic/governmental institutions, there might be a potential conflict of interest depending on their specific research priorities and funding sources. However, without more information, it is hard to determine the extent of this potential conflict.
Identified Weaknesses
Limited Comparison with State-of-the-Art
The paper lacks a clear comparison with existing state-of-the-art smoothing techniques, making it difficult to assess the novelty and practical advantages of the proposed method.
Limited Dataset and Generalizability
The simulation results are based on a single dataset from May 2013, which limits the generalizability of the findings. The performance of the proposed method under different weather conditions and solar irradiance profiles is unknown.
Lack of Cost-Benefit Analysis
The paper does not provide a detailed cost-benefit analysis of the proposed method. The economic feasibility of implementing the Savitzky-Golay filter and battery storage system needs further investigation.
Lack of Detail on Battery Control
The paper briefly mentions the integration of a battery charging control based on charge-discharge depth SoC, but does not provide a detailed explanation of its implementation or its impact on the overall system performance.
Simplified Grid Model
The paper assumes a fixed ramp rate limit for the grid, which may not be realistic in practice. The impact of varying grid requirements and constraints on the performance of the proposed method is not explored.
Rating Explanation
The paper presents a relevant topic and a reasonable methodology for smoothing solar power fluctuations using Savitzky-Golay filtering. However, the limited dataset, simplified grid model, and lack of thorough comparison with other smoothing techniques and cost analysis prevent a higher rating. The clarity and presentation of the paper could also be improved.
