Abstract

This paper provides a comprehensive harmonic picture of Photovoltaic operations integrated with the Electric Power System (Photovoltaic on-grid). Harmonics in Photovoltaic on-grid are generated from the inverter. One way to reduce harmonics is by installing a filter. Apart from reducing harmonics, filters can improve the system power factor value. This research examines the effect of variations in Photovoltaic on-grid filter parameters on inverter power capacity using Simulink/Matlab simulation. The FFT (Fast Fourier Transform) method is used to determine the harmonic order and THD of the current and voltage of the system on the side before and after the filter. The simulation results show changes in filter parameter variations for Qc (Var) values ​​giving THDi and THDv values ​​before and after filter installation using the FFT approach.

Geographically, MTs Negeri 1 Mataram is located in the Mataram city area with a distance of approximately 1 kilometer from the Mataram University campus, which is the place of duty for the team carrying out this service. The method for implementing this service is through socialization and education about the basic concepts of solar power plants, how they work, and their environmental and social benefits through various stages including presentations, discussions, practical demonstrations of PLTS modules, and assessing student understanding through post-tests. and pre-test. Practice demonstration of PLTS modules. Evaluation of the 20 students who took part in this activity showed an increase in their awareness regarding the importance of PLTS in sustainable energy and environmental conservation, because the average post-test and pre-test score was above 83. This is expected to encourage active participation of students in supporting renewable energy in the future

Abstract

The allocation of LPG gas subsidies has increased, putting a burden on state finances, while surplus electricity production is not being utilized optimally. Electrical energy can replace LPG gas by replacing the gas stove with an electric stove. This conversion requires adequate installation to ensure the safe and secure operation of the electric stove. The implementation of the conversion program must be supported by community readiness regarding standard electrical installations for electric stoves in the form of training. Training activities were carried out in Nyurlembang Village, Narmada, West Lombok, as a community service activity. This activity aims to educate and train the public about repairing and redesigning electrical installations for electric stoves. Training methods include lecture, discussion and practice methods. Before and after the activity, participants are given a written test to determine the success of the training activity. The test results show an average score before and after training of 38.33 and 66.00 for the range 0-100. These results show that the training was quite effective with an increase in participants' theoretical and practical knowledge of 27.67.

Abstract

Electricity consumption has become an integral part of daily life and is pivotal in supporting various aspects of human life. North Aceh Regency, a tropical region in Indonesia, experiences significant seasonal fluctuations between the rainy and dry seasons. This research aims to investigate and analyze the impact of these seasonal differences on electricity consumption patterns by consumers in the region using the IBM SPSS statistical method. Monthly electricity consumption data from consumers in North Aceh Regency over a specific period were collected and analyzed using IBM SPSS software. Descriptive statistical analysis, hypothesis testing, and regression models were employed to identify significant differences in electricity consumption between the rainy and dry seasons and to understand the factors influencing consumption patterns. The results of the analysis indicate a significant difference in electricity consumption between the rainy and dry seasons in North Aceh Regency. The dry season shows an increase in electricity consumption, possibly related to factors such as the use of air conditioning and additional lighting.

Abstract

One of the renewable energy power plants whose construction is very massive is the solar power plant (PLTS) because it can be built anywhere in Indonesia. The type of PLTS with cheap investment is the on-grid system. This study aims to analyze the performance of the 600 Wp on-grid PLTS based on data loggers. Data logger is a data recording system designed using an Arduino Nano microcontroller equipped with sensors such as a solar radiation sensor (PYR20), temperature and humidity sensor (DHT22), PV module temperature sensor (DS18B20), DC voltage sensor, DC current sensor (ACS712), real time clock (DS3231), AC digital wattmeter module (PZEM-004T 10 A) and Micro SD Card Mini to store measurement data. The data logger is set to store measurement data every 5 minutes. The results of sensor measurements after calibration have an average measurement error of 5.20%, 0.56%, and 0.68% for the PYR20 irradiance sensor, 50 V range DC voltage sensor, and DC current sensor (ACS712). Based on the results of data logger recording, the 600 Wp on-grid PLTS system has a PV module efficiency in the range of 2.45 - 19.2% with an average of 8.60%, and the inverter (smart microgrid inverter) has an average efficiency of 89.40%.

Abstract

Novel selective modal analysis for the determination of low frequency power flow oscillation behaviour based on eigenvalues with corresponding damping ratio, cumulative damping index, and participation factors is proposed. The power system being investigated consists of three large longitudinally interconnected areas with some weak tie lines. Different modes, such as exciter modes, inter area modes, and local modes of the dominant poles are fully studied to find out the significant level of system damping and other factors producing power flow instability. The nature of the energy exchange between area is determined and strategic power flow stability improvement is developed and tested.

Abstract

Deregulasi pada sistem tenaga saat ini membawa kecenderungan untuk membangun unit-unit pembangkit yang letaknya tersebar dekat dengan pusat-pusat beban. Unit ini umumnya berkapasitas kecil berbeda dengan kondisi sistem lama yaitu pembangkit berkapasitas besar terletak terpusat (lumped). Beroperasinya unit pembangkit tersebar membawa kecenderungan transfer daya inter dan antar area menjadi berkembang. Hal ini mengakibatkan perubahan titik operasi pembangkitan dan pola aliran daya yang akan menyebabkan masalah pada stabilitas dinamis sistem. Penelitian ini bertujuan mengetahui pengaruh unit pembangkit tersebar terhadap stabilitas dinamis sistem tenaga. Pada penelitian ini dibuat dan diuji program untuk stabilitas dinamis dengan program aplikasi MatPower 3.0 dan MATLAB 7.0.4. Pembangkit tersebar (DG) yang diteliti adalah PLTM yang masuk ke salah satu bus pada sistem 14 bus dan 4 pembangkit. Hasil penelitian menunjukkan sistem yang diteliti berada  pada kondisi stabil untuk beban puncak dan gangguan penambahan beban 10%. Pengaruh DG membawa dampak perbaikan pada pembangkit yang terhubung langsung dengan DG rata-rata sebesar 0.2280 pu (0.26 %), tetapi memberikan respon keterlambatan  nilai settling time terhadap gangguan rata-rata sebesar 13,84 detik.

Abstract

The Boost DC-DC Converter plays a significant role in renewable energy applications and electric vehicles, serving to increase the output voltage from low-voltage sources. This study aims to analyze the performance of the Interleaved Boost Converter with Linear Quadratic Regulator (LQR) control compared to open loop and PID control. The research methodology involves designing and simulating the converter using MATLAB/Simulink, where various control configurations are tested to assess their ability to regulate output voltage. Simulation results show that the Interleaved Boost Converter with LQR control produces a stable output voltage of 28 volts with the fastest response time (9.629 µs) and no overshoot. In contrast, the PID control configuration delivers an output voltage of 28.46 volts with a maximum overshoot of 0.510% and a slower response time (25.177 µs). The open loop configuration, despite having the fastest response time (19.768 µs), results in significant voltage ripple. The conclusion of this study emphasizes that LQR control is superior in terms of stability and quick response and is recommended for applications requiring high performance. Future research is suggested to focus on optimizing PID control parameters and evaluating LQR performance under dynamic load conditions
