Abstract

Generator scheduling remains an intriguing issue within the energy industry. It relates to the optimization of production costs, where system operators must select the optimal combination of available resources to minimize production costs. This paper proposes an enhancement to the Equal Incremental Cost (EIC) Method using Adjustable Gamma Control (AGC) in generator scheduling. Iterations begin with an initial lambda value, then gradually increase with the application of the factor until power demand is met. A variable of 10% is used as an adjustment step in the optimization method. The proposed method is capable of achieving convergence with 100% accuracy, where the power generated by all generators precisely matches the load demand (2,650 MW), at a cost of USD 32,289.03. EIC-AGC ranks second-best after VLIM, albeit with the consequence of consuming 195 seconds. This method is expected to have a significant impact on designing highly accurate economic dispatch techniques. Thus, generator scheduling will lead to a reduction in operational costs compared to current practices.

Abstract

In electric power distribution systems, the distance between the load bus and the generating unitsignificantly affects grid efficiency and reliability, with longer distances causing greater voltage drops. To mitigatethis, Distributed Generation (DG) is increasingly being used, generating electricity closer to the point of consumption.Determining the optimal DG location requires advanced metaheuristic methods. This research proposes the Grey WolfOptimizer Algorithm (GWOA) to determine optimal DG placement, tested on the IEEE 14-bus distribution grid. Themethod generated two scenarios: In the first scenario, power losses were reduced by 98.1465% for real power and98.9538% for reactive power compared to the existing conditions, while voltage increased by an average of 0.0127 p.u.for all buses combined. The second scenario also showed a notable voltage increase of 0.0064 p.u. The GWOA methodproves to be an efficient and effective solution for DG placement, enhancing system reliability and protectinghousehold electronic devices.

Abstract

The TSE-Creative Teaching’s Workshop is a community service program by the undergraduate Energy Systems Engineering faculty aimed at sharing knowledge with teachers at SMKN 4 Bandung. This workshop aims to assist teachers in integrating educational technology into their teaching methods. Teachers will learn how to use hardware to install Wind Power Plants (PLTB) and simulate PLTB installations. This aims to enhance the teachers' experience so they can transfer their knowledge to students, preparing them for the clean energy transition in the digital era. During this activity, the teachers achieved an average accuracy of 61% in answering questions correctly. Based on the questionnaire results, 100% of SMKN 4 Bandung participants agreed or strongly agreed on the relevance of the implemented community service program. Through this training, it is expected that teachers will improve their understanding of renewable energy, inspiring and guiding students in understanding the importance of renewable energy and their role in environmental conservation. Additionally, this training is expected to strengthen the school's involvement in sustainable practices and spread awareness about the importance of renewable energy within the local community.
