Abstract

This paper discusses the design and simulation of the Cascade Greinacher circuit to increase the dc output voltage and current. The voltage increasing circuit using the Cockroft-Walton method has a large output voltage ripple and voltage drop. Meanwhile, half wave and full wave rectifier circuits are only capable of producing a DC output voltage and do not reach the maximum voltage value. In addition, the load resistance at each input power saturation is different and high frequencies require the addition of a capacitor circuit. Therefore, the Greinacher Doubler Circuit (GDC) rectifier is proposed with a modified diode and capacitor series arranged in nine levels in parallel. The circuit modification is used as a DC output voltage rectifier to reduce output voltage ripple. Then the circuit modification was tested by simulating the PSIM software and varying input voltages. Simulation testing uses a 220 volts voltage source, 50 Hz frequency, and component specifications for a single-phase step-down transformer 220 to 12 volts, 8 diodes (DXN, DN/DXN1, DN1/DXN2, DN2/DXN3, DN3), 8 capacitors with 4700Uf value (CXN, CN/CXN1, CN1/CXN2, CN2/CXN3, CN2), and 100 Ω resistor. simulation results which produce a voltage greater than 3 times the input voltage, namely 35.7 V and a current of 0.98 A. Even though at times 0.001 seconds and 0.0035 seconds and 0.0054 seconds the output voltage and current are constant at 4.9 volts respectively, the current is 0.03 A, current 0.08 A and current 0.013 A. The output voltage Vout, Vs and current continue to increase when it reaches 1 second.

Abstract

This research aims to design and develop an advanced monitoring system for solar cells, incorporating solar tracking technology and equipped with an energy storage protection system. In Indonesia, the substantial potential of solar energy remains underutilized, despite the country's advantageous equatorial location, which provides a solar radiation intensity averaging 4.5 kWh/m² per day. The proposed system in this study seeks to maximize solar energy capture by employing a tracking mechanism that aligns the solar cells with the direction of sunlight throughout the day. Additionally, the system is designed with an integrated protection feature to prevent battery overuse, thereby extending the battery's lifespan and ensuring efficient energy storage. The research utilizes an Arduino Uno microcontroller, Light Dependent Resistor (LDR) sensors, and an INA219 sensor module as the primary components for accurate measurement and real-time monitoring. The system's effectiveness is evaluated based on its ability to optimize solar energy reception and maintain the longevity and efficiency of the energy storage system. Experimental results demonstrate that the developed system significantly improves the efficiency of solar energy capture by the solar cells and provides robust protection for the energy storage mechanism. This study contributes to the field of renewable energy by offering a practical solution for enhancing solar energy utilization in regions with high solar irradiance, thus promoting sustainable energy practices and reducing dependence on non-renewable energy sources.

Abstract

The need for electrical energy is currently increasing in line with technological advances, but the energy supply is still insufficient. There have been many developments of power plants using sunlight. Therefore, this study is to analyze the costs required for planning a 200 Wp PLTS as a renewable energy source. This research was conducted in the Dringu sub-district, Probolinggo district, on Thursday 6 June 2023 at 08.00 - 14.53 WIB. The research begins with data collection of sunlight intensity. The highest light intensity on the first day was recorded at 12:38 WIB was 1622 Lux, the second day the sunlight intensity was recorded at 12:02 WIB was 1607 Lux and the third day the sunlight intensity was recorded at 12:32 WIB was 1606 Lux. With the output power of solar panels that produce 1.18 kWh/Day, the amount that can be generated for one day is Rp. 1,704.75 and in one year is Rp. Rp. 613,708.56. The cost of making a 200 Wp PLTS is Rp. 3,977,000 so that it takes 6.4 years to recover the initial investment costs. The total advantage of using a 200 Wp solar panel is Rp. 15,097,230.56.

Abstract

This study aims to evaluate the impact of RLC loading on the power stability and power quality in Wind Power Plant (PLTB) systems. The RLC is applied to stabilize the power generated by the PLTB system, which tends to fluctuate due to wind speed variability. The testing was conducted by measuring the output power of the PLTB system loaded with various RLC configurations. The results show that RLC loading can enhance the apparent power stability and efficiency of the PLTB system. The resistive load (R) yielded the best performance, improving the power factor to 0.95 and maintaining relatively stable output voltage. Meanwhile, the LC loads exhibited lower efficiency with a reduced power factor, but still played a role in balancing reactive power. The reduction in reactive power for inductive and capacitive loads indicates that RLC loading can help reduce power waste and improve power quality. This research makes a significant contribution to the development of more efficient and stable PLTB systems and more reliable renewable energy-based power plants, particularly in managing power stability in the face of fluctuations caused by wind variability.
