Revision 1
13 Mar 2024 Author Response The authors would like to thank the editor and reviewers for reviewing the manuscript entitled “Optimal Sizing and Power Losses Reduction of Photovoltaic Systems using PSO and LCL Filter”, PONE-D-24-05446. The authors appreciate your insightful comments and suggestions, which have greatly contributed to improve the quality of their work. In response to your valuable feedback, the following revisions are being made in the revised manuscript. Note: The modifications made in the revised manuscript based on the reviewer’s comments are highlighted with yellow colour. Response to Reviewers Reviewer #1: The manuscript proposes "Optimal Sizing and Power Losses Reduction of Photovoltaic Systems using PSO and LCL Filter"s. The reviewer's concerns are as follows: 1- The novelty of this study is not clear. A flow chart showing the processes should be added to the article. In this paper, the particle swarm optimization (PSO) is used to control a boost converter and to evaluate the power losses and the harmonic distortion rate. The test on the IEEE 14 bus standard makes it possible to determine the allocation or integration nodes for other sources such as biomass, wind or hydrogen generators. This approach has given the possibility and feasibility to know where to inject power from other sources accordingly at each node. For instance, the THD is used to evaluate the respect of the normalized rate of harmonics at the common point of coupling. As suggested by the respected reviewer, the flowchart of the PSO algorithms is added in the revised manuscript. 2- The formulas of THD for current and voltage should be given in the introduction part of the article. As suggested by the respected reviewer, the THD formula is provided in equations (30 and 31) along with the revised manuscript in the introduction section. 3-Reference numbers need to be increased. We thank the reviewer for this relevant suggestion. As suggested by the respected reviewer, reference numbers have been increased. Reviewer #2: Particle swarm optimization (PSO) is used to control a boost converter and to evaluate the power losses and the harmonic distortion rate. The test on the IEEE 14 bus standard makes it possible to determine the allocation or integration nodes for other sources such as biomass, wind or hydrogen generators. the idea is good written but it needs further improvements like: 1. PSO is very old optimization. can you compare your results with the recent optimization approaches? We thank the reviewer for this relevant suggestion. As suggested by the respected reviewer, recent optimization approaches are provided to compare the obtained results. The comparison is done in table 2. 2. Convergence curve for only one optimization! please, use three recent techniques and compared. We thank the reviewer for this relevant suggestion. As suggested by the respected reviewer, three recent techniques are used and compared with the results in table 2. 3. Refs. [21] & [23] are the same, please modify it. We thank the reviewer for this relevant suggestion. As suggested by the respected reviewer, the duplicated reference is modified 4. Consider discussing potential limitations and future research directions to guide further exploration in this field. We thank the reviewer for this relevant suggestion. As suggested by the respected reviewer, limitations and future research directions are given along with the manuscript. 5. useful citations may be used like: 10.1109/ACCESS.2023.3317980 10.1371/journal.pone.0287772 10.1016/j.asej.2022.102047 As suggested by the respected reviewer, these papers are cited in the revised because we found them important and suitable with our topic. https://doi.org/10.1371/journal.pone.0301516.r002
