Price-Response Matrices Design Methodology for Electrical Energy Management Systems Based on DC Bus Signalling
Round 1
Reviewer 1 Report
The topic is worth investigating but the development of it, in its current state, is deficient, so minor modifications of the current text may be required to correct said deficiencies.
The main deficiencies are summarized in the following points:
- The formatting of the entire paper is in many problems, so please follow the template and make changes. For example, [1-2] should be revised to [1,2].
- Literature should be improved. No importance has the single mention to different systems as in lines 34-35. What is the added contribution of such studies?
- What is the overall research framework of the paper? Please give an explanation in the introduction.
- What is the innovative nature of this paper?
- Please state clearly the research question and mention it in introduction and conclusions. In the last section, add the potential and limitations of your approach and results as well. What would be the added value of your research?

Reviewer 2 Report
- Price-Response Matrices (PRMs) is mostly applicable for which type of energy management. Kindly add technical justification
- In the proposed work, several systems (such as Diesel generator, Supercapacitor, battery bank, PV generator etc.) have been used. Kindly include its rating and name plate information for each system for easy unstinting to the researchers.
- Compare the results with existing approach as well as one advance method
- Novelty part of the proposed work is not clear. Kindly explain in detail.
- IEC TS 60364-8-3 provides requirements and recommendations on technical parameters and their limiting values influencing the following: safety (protection, alarm etc.) and proper functioning for electrical installations. In this situation, how is it different than IEC 62850 in term of safety and function?
- In the proposed approach (figure 3), different converters are used for different uses (such as PV dc-dc, Batteries dc-dc, dc-ac grid etc.). Are these centralized controlled or isolated mode control. If isolated then why not centralize. Kindly add technical detail in vice versa mode also.

Reviewer 3 Report
This paper is an experimental study on the application of Price-Based Power Management strategy to a single PEI with three priority loads, battery energy storage, and a dc-ac converter connected to the ac grid. Results show that power balance is achieved without any knowledge of the power of each element.
The paper is interesting because it demonstrates an alternative to the classical droop control. However, as the authors recognized in table 7, the proposed strategy requires (as opposed to the hierarchical droop control):
a) an accurate and fast voltage detection
b) high bandwidth links
1) How can the limitations above mitigated ? Why can the price based power management strategy an attractive choice despite of the mentioned limitation ?
2) The methodology to determine User parameterization for the price response matrices in Fig.6 has not been thoroughly explained, especially with respect to levels of price determining the action: "buy energy from the DC bus" or "sell energy from DC bus". It appears that multiple choices are possible, how do they affect system performances ? Is the algorithm tuning effort affordable ?
3) Results are clearly presented. However there are cases where the dc bus cannot be controlled during the transient (in scenario 2 the battery is fully discharged and high priority loads are turned off, price increases to $8). How does the proposed strategy cope with those emergency cases ?
