Round 1
Reviewer 1 Report
This paper is a review of the methodologies used for the optimal location, sizing, and 1operation of Distributed Generators (DGs) and Energy Storage Systems (ESSs) in electrical networks. The paper is well written and organized, and from my point of view, only a few typos and format issues can be corrected to improve the quality of the paper.
1. The proportion of the latest published literature should be increased, especially the papers in 2021-2022.
2. Can the authors show more related regulations of the world in other countries, as only the regulations of Columbia are given in this manuscript.
3. The figures should be formatted, e.g., the subtitle in figure 7 is missing which leads to the misunderstanding of this figure, and the font size in figures 4-6.

Reviewer 2 Report
Overall, this paper is well-organized and comprehensive. However, the operating conditions of DGs and ESSs in microgrids are more than the ones provided in this paper. For instance, power losses minimization of DGs and ESSs with communication failure (Power Loss Minimization of Parallel-Connected Distributed Energy Resources in DC Microgrids Using a Distributed Gradient Algorithm-Based Hierarchical Control) and cyber attacks (A High-Order Differentiator Based Distributed Secondary Control for DC Microgrids Against False Data Injection Attacks). Besides, optimization techniques are more than PSO, GA, SO, and SA (Control Algorithms for Energy Storage Systems to Reduce Distribution Power Loss of Microgrids). Furthermore, advanced grid-connected power electronics are not mentioned in this paper. For example, solid state transformer (Review of Solid-State Transformer Technologies and Their Application in Power Distribution Systems) and Electric Springs (Mitigating distribution power loss of DC microgrids with DC electric springs, Reducing distribution power loss of islanded AC microgrids using distributed electric springs with predictive control). For economic dispatch, a system-level optimization including renewable energy sources, fuel cells, battery storage systems, and active loads may also be considered (Operating cost reduction of DC microgrids under real-time pricing using adaptive differential evolution algorithm). Last but the least, would you please provide some outlooks of future research in the last section?
