Abstract

Generators play an important role in providing electrical energy in power systems. Changing loads on generators in an interconnected system can cause voltage instability. The generator voltage can be regulated through excitation current, which is a DC electrical supply that amplifies the field in the generator to produce electrical energy with an output voltage that depends on the excitation current. The purpose of this study is to analyze the effect of synchronous generator load changes on the excitation system on the generator and the effect of excitation current on the generator voltage of unit 2 of Maninjau Hydroelectric Power Plant. The type of excitation system at Maninjau Hydropower Plant is an excitation system with PMG, the output voltage of unit 2 generator of Maninjau Hydropower Plant is 10 kV. The method used in this research is by looking at the data read on the generator load data and the excitation current read on the DCS parameters. Furthermore, from the data obtained, the generator voltage value is in the range of 10.3 kV - 10.6 kV. This shows that the AVR component works well in reading and giving commands in regulating the generator output voltage. From the data obtained, the value of load changes in the generator affects the value of the injected excitation current. The lowest load is at 10.4 MW with an injected excitation current value of 8 A and the generator voltage is at 10.6 kV, while the largest load is at a value of 16.5 MW with a higher excitation current value.

Abstract

In the context of increasing global demand, and the importance of renewable energy sources. There is a need to focus on renewable energy management and explore more efficient sources of energy generation. In recent years, the rise of the transition from fossil energy to renewable energy and its decreasing cost have posed new forecasting problems of interest to researchers, namely, the knowledge in advance of the electricity consumption that wind power plants may generate in the future. Recognizing the need to improve renewable energy management as a strategy to search for better and more efficient sources of energy generation, a system for forecasting the generation of electricity consumption by wind power using neural networks is proposed that allows maximum utilization of the potential that can produce wind power. A backpropagation neural network is used as an artificial intelligence component to accurately predict electricity consumption. The network is a multi-layer perception (MLP) network that uses a reverse transcription learning algorithm to train a feed-forward neural network to perform a specific task. The Levenberg-Marquardt algorithm is used to improve network training and evaluate its performance. In this study, the suggested approach trains the feed-forward neural network for the specified task using a multi-layer perception (MLP) network and a backpropagation learning method. By modifying the weights of the connections between neurons, the number of neurons in the hidden layers is optimised in order to reduce the output error in comparison to the desired target values and achieve high accuracy. Support vector machine (SVM) and auto-regressive integrated moving average (ARIMA) models' performances are compared to those of the suggested model.

Abstract

This study aims to determine the optimal C/N (carbon/nitrogen) ratio of a mixture of chicken manure and water hyacinth in the anaerobic fermentation process, as well as to evaluate the potential for biogas and electricity production with and without the use of a starter. In this experiment, a mixture of 300 kg of chicken manure and 200 kg of water hyacinth, with an additional 75 kg of starter, was used to achieve a more ideal C/N ratio. The fermentation process was carried out in two scenarios: one with a starter and one without a starter, to compare the results. The analysis results show that the use of a starter significantly increased the volume of biogas produced, which was 89.06 m³, compared to 70 m³ produced without a starter. In addition, the potential for electricity generation also increased significantly, from 329 kWh without a starter to 418 kWh with a starter. The biogas production increased by 27.23% with the use of a starter. These findings suggest that the use of a starter not only increases the volume of biogas but also improves energy conversion efficiency, making it an effective method to enhance anaerobic fermentation outcomes and achieve a more ideal C/N ratio, which in turn can optimize renewable energy production from organic materials.

Abstract

Human feces is an abundant organic waste that poses environmental risks if not managed properly. One sustainable solution is to convert it into renewable energy in the form of biogas. This study aims to analyze the potential of utilizing human feces as an alternative fuel source at the Jabal Nur Islamic Boarding School in Kandis, Riau, Indonesia. A quantitative approach was used, incorporating both primary and secondary data. The results indicate that with 820 students, the boarding school produces approximately 328 kg of feces per month, which can generate around 60.5 m³ of biogas. This biogas can reduce LPG consumption by 27.48 kg per month. The economic feasibility analysis reveals that while the project is environmentally viable, it is not yet financially profitable, with a Net Present Value (NPV) of -Rp1,174,700, a Net Benefit-Cost Ratio (Net B/C) of 0.856, and a Payback Period (PBP) of 7.18 years. Nevertheless, human feces-derived biogas holds significant potential as an environmentally friendly and sustainable alternative energy solution.

Abstract

Limited access to electricity in remote areas is a serious challenge in national energy distribution. This study aims to examine the use of Stirling engines as an environmentally friendly alternative energy source that can be used for small-scale power supply systems. Stirling engines were chosen because of their ability to convert heat energy from various sources into mechanical energy, which is then converted into electrical energy. The research methods include prototype design, performance testing, and interviews with experts in the field of energy conversion. The test results show that Stirling engines are capable of producing an average electrical power of 5.7 watts at an operating temperature of ? 300°C, with an energy conversion efficiency of around 15–20%. The integration of a microcontroller-based power control system has succeeded in increasing output stability and facilitating system performance monitoring. The interview results support that this technology has the potential to be further developed in areas that have not been reached by electricity. This study concludes that Stirling engines are an alternative solution that is applicable, economical, and supports the development of renewable energy in Indonesia.
