Abstract

DC-DC Converter is an important component in modern electric power systems. This converter is used to convert DC voltage from one level to another, which is indispensable in various types of applications ranging from everyday electronic equipment to industrial use. DC-DC full bridge converter is one of the commonly used power converter topologies. However, these converters often face challenges in the form of voltage spikes that can damage components and oscillations that interfere with system performance. In this study the authors designed a RCD snubber circuit that could overcome this problem. The RCD snubber circuit consists of resistors, capacitors and diodes which are connected in parallel to each MOSFET. The test results show that before the snubber circuit is installed, there is a voltage spike that reaches 2 times the input voltage to more. In addition, high-frequency oscillations occur which require 1µs and 4µs to reach steady state. After adding the RCD snubber circuit, retesting was carried out and it was found that the voltage surge had reduced to about 1.2 times the input voltage. In addition, the oscillations that occur also require faster time to reach steady state, which is only 0.4µs and 1.5µs. Based on the test results and calculations, the power dissipation on the snubber resistor is also obtained. At an input voltage of 12V, the power dissipation is 2,234% input power, then at an input voltage of 24V, the power dissipation is 2,273% input power and at an input voltage of 36V, the power dissipation is 1,983% input power. From all the test results show that the RCD snubber circuit is able to reduce the voltage spikes and also the oscillations that occur at the moment of transition. Keywords: DC-DC full bridge converter, snubber, spike, oscillation, transition, dissipation

Abstract

PPSDM Migas is a government-owned company engaged in the energy sector under the auspices of the auspices of the Ministry of Energy and Mineral Resource with a solar energy potential of 5,03 kWh/m2 /day obtained from the Meteonorm 7.1 software. PPSDM Migas has a total consumption of electrical energy in 2021 of 1,866 MWh. The construction of the On-Grid solar system at PPSDM Migas is expected to implement alternative energy resources and save electricity costs. The purpose of this study is to determine a feasibility analysis of solar power plants (PLTS) in technical and economic aspects using the PVsyst software simulation. The solar power plants system (PLTS) at PPSDM Migas has an installed capacity of 120 kWp which is divided into 8 point installation locations with a total of 420 units of solar panel with the Yingli Solar brand with a capacity of 280 Wp. There are 2 types of configuration systems based on their inverter capacity, which are the configuration of 10 kW inverter and 20 kW inverter. The PVsyst software simulation in 2021 produces 195,4 MWh per year of energy or can supply around 10,47% of the total energy consumption of PPSDM Migas. In 2021, this solar system is capable of producing 127,3 MWh of energy. Performance Ratio (PR) in one year is 84,4% from PVsyst, 85% from the theoretical calculation, and 58,9% from field results. The results of the economic feasibility analysis shot that Life Cycle Cost (LCC) is Rp. 2.021.116.083, and the value of the Cost of Energy (COE) is Rp. 963,59 /kWh.The results of the investment feasibility analysis show the value of Net Present Value (NPV) is Rp. 632.633.554, the value of the Profitibality Index (PI) is 1,36, and the Pay Back Period (PBP) or the year of return after the 14th year. Based on the results of the analysis in the technical aspects, it can conclude that the solar system at PPSDM Migas still needs performance improvement, while in the economic aspects, it is considered that the project is feasible to continue.

Abstract

Geographically, Indonesia is located on the equator which is always exposed to sunlight throughout the year, so solar energy has great potential to be developed. In general, there are two technologies that utilize solar energy, which is photovoltaic (PV) technology and solar thermal technology. The main problem of photovoltaic systems is the low efficiency of the electricity produced. To maximize the work of photovoltaic (PV) can be obtained through the Maximum Power Point Tracking (MPPT). One of them is MPPT perturb & observe (P&O). The increase in radiation intensity is proportional to the output power. When the radiation intensity is high, the temperature also increases. When the temperature increases, the efficiency of photovoltaic will decrease. In this study, a cooling system was designed that uses water at MPPT perturb & observe (P&O) with a converter used is a boost converter. The results of this study prove that a decrease in the temperature of solar panels by 21.190C can increase the power generated by 8.748%. keywords─ Photovoltaic, MPPT, Perturb & Observe, Boost Converter, cooling system.

Abstract

Efisiensi energi merupakan fokus utama dalam menghadapi perubahan iklim dan keberlanjutan lingkungan. Salah satu cara untuk mencapai efisiensi energi adalah dengan meningkatkan pengaturan air yang seringkali menjadi sumber pemborosan energi listrik. Penelitian ini berfokus pada sistem pengaturan air tandon di Perumahan Giri Palma. Sistem saat ini menggunakan pengaturan manual yang rentan terhadap kelalaian dan ketidaktepatan waktu operator, menyebabkan pemborosan energi listrik dan gangguan pada suplai air. Untuk mengatasi masalah ini, penulis merancang sebuah proyek prototype sistem otomatisasi pengaturan air tandon berbasis LoRa. Tujuan penelitian ini adalah menyajikan solusi untuk merancang sistem otomatisasi pengaturan air tandon berbasis LoRa dan mengevaluasi keefektifannya. Penggunaan mikrokontroler sebagai pengatur kerja komponen otomatisasi pada setiap tandon, serta teknologi LoRa sebagai pendukung komunikasi jarak jauh antar node digunakan dalam penelitian ini. Sensor ketersediaan air sumur dan sensor ketinggian air tandon ditempatkan untuk mengontrol kerja pompa. Setelah dilakukan implementasi dan pengujian, hasil penelitian menunjukkan bahwa prototype sistem otomatisasi mampu mengisi tandon dengan baik sesuai dengan spesifikasi yang ditetapkan. Hal ini menunjukkan bahwa sistem otomatisasi pengaturan air tandon berbasis LoRa dapat menjadi solusi efisien dalam penghematan energi listrik dan penyediaan air yang stabil di Perumahan Giri Palma. Kata kunci— Efisiensi energi, pengaturan air tandon, LoRa, mikrokontroler, sensor, otomatisasi.

Abstract

Renewable energy is an alternative energy as a substitute for fossil fuels, one of which is solar energy. The problems with photovoltaic technology are low energy conversion efficiency and inconsistent solar radiation. So that from these problems it is necessary to optimize the output power of solar panels using Maximum Power Point Tracking (MPPT) which works by tracking the maximum power point that can be generated by the solar panel system and keeping it always working at that point. In this study, this MPPT Solar Charge Controller uses a Buck-Boost Converter, as well as Incremental Conductance and Hill Climbing as control methods. Both of these methods will be analyzed by comparing the increase in output power through MATLAB Simulink software simulation. Based on the results obtained from the simulations and calculations using the two MPPT methods, it was found that there was an increase in the output power of the solar panel system by 31.17W or 56.9% for the Incremental Conductance method and 7.23W or 13.2% for the Hill Climbing method, compared to PV systems without using MPPT.
