Voltage drop using Arduino Uno and monitored in real time through LabVIEW simulation” (Paper ID: Ijies3819) was the result of the bachelor theses by Yohanes Artha Setiawan last year. My reasoning for choosing the corresponding author was because Yohane's ability to write papers in English was relatively limited, so I helped him write and submit the results for publication in English to the International Journal of Intelligent Engineering and Systems ( IJIES) including communication with the editor about its progress (also revision of this paper).

The observed parameters are overhang depth 𝑉𝑆, overhang deviation 𝑉𝐿, load 𝑇𝐻𝐷𝑉, source 𝑇𝐻𝐷𝐼 and real-time simulation. With a sag depth of 𝑉𝑆 65%, this topology results in a sag deflection of 𝑉𝐿 0% and a load of 𝑇𝐻𝐷𝑉. Ye, et.al [26] proposed an elliptical recovery method for voltage drop compensation and power factor correction.
31] implemented a VSI-SPWM-based single-phase DVR model with a NI-myRIO-1900 interface monitored in real time by LabVIEW. Based on the research results of [31] and [32], this study implemented a single-phase DVR model using the UVTG method with an Arduino-Uno interface monitored in real time by LabVIEW. With a sag depth 𝑉𝑆 of 80%, the proposed model is capable of producing a sag deviation 𝑉𝐿 of 6.4%.
The proposed study is able to provide the best performance because it is able to produce the source 𝑇𝐻𝐷𝐼 lower than [28] and the source 𝑝𝑓𝑡𝑟𝑢𝑒 is higher than [26]. Another contribution is that by using the Arduino-Uno interface, the proposed model can be run and monitored in real time with LabVIEW. 5 with the legend marked with red circles (A to G) to help the reader see and understand detailed section of software design using LabVIEW interface for simulating signal.
Through simulations/experiments, the authors must justify the effectiveness of the proposed method by comparing it with existing methods. Many articles report the effectiveness of the proposed method in comparison with existing methods.

1 shows a single-phase DVR supplied by BES using load voltage control with the UVTG method. The series active filter protects sensitive loads against multiple voltage disturbances from the source bus. In [31], the control method of source and load voltage in a three-phase series active filter has been discussed.
Using the same procedure, the authors propose the same method for active filter control in single-phase series as shown in Figure. A single phase locked loop (PLL) is used to generate sinusoidal unit vector templates with a phase delay using the sine equation. The reference load voltage (𝑉𝐿∗) is then compared to the sensed load voltage (𝑉𝐿) by an SPWM controller used to generate the desired four-port signal on a single-phase active filter in series.
The step-up transformer installed in series with the load acts to inject the voltage from the series active filter to the load. The goal is for the series active filter to be able to inject enough current to compensate for the voltage drop at a level of 10% to 90%. The Arduino Nano flip-flop acts as a timer to run system simulations using a single-phase DVR-BES without and with drop voltage.
This timer is expected to operate when there is a sag voltage and automatically commands a single-phase active filter to inject a voltage compensation into the load so that the load voltage will remain stable. All data displayed in LabVIEW is real-time and continuous data as long as the single-phase DVR-BES system is operated after the system.
Results and discussion
9 Performance of case deviation of 𝑉𝐿 for single-phase DVR-BES system on three load type from 13.03 V to 8.06 V. 10 Performance of source true power factor for single-phase DVR-BES system on three load type. 11 Performance of load true power factor for single-phase DVR-BES system on three load type The percentage of load voltage deviation for the system with sag deviation of 𝑉𝐿 for the three load types are respectively. 8.87%.
Alternatively, for the step-down system, the single-phase DVR-BES system produces the true power factor of the source ( single-phase supplied by BES with load voltage controlled by the UVTG method.
During voltage drops, the single-phase DVR-BES system can maintain the load voltage for all types of loads.
