Abstract

In reality, the electric power system is run by combining several production units to commit to meeting changes in load demand at each operating time. Apart from that, it also takes into account efforts to reduce overall costs while maintaining the specified technical limits. The general thing that is often done to achieve this condition is carried out with an economical operational approach which leads to minimizing operational costs. During 24 hour operations, the model that is often used is Dynamic Economic Operation (DEO) which takes into account changes in load demand over a 24 hour seven day period. This study uses the IEEE-62 bus system as a model, which is optimized using the Orca Algorithm. The load flexibility pattern is based on the effect of charging integration for Electric Vehicles (EV). The simulation results show that the Orca algorithm solves problems with fast iteration and provides the best results. The Orca algorithm provides good levels of convergence, power output and overall operational costs. EV distances and routes also have varying driving characteristics and varying power utilization. In terms of travel modes, which include one way and two trips, it has a mobility of 208,000 EVs, with respective distributions for working/business/study, service/shopping, leisure time, and other purposes.

Abstract

The Industrial Electronics Practicum is an advanced learning process complementing theoretical knowledge and is mandatory for every student in the Energy Conversion Engineering (TKE) Study Program at Ujung Pandang State Polytechnic (PNUP). Nevertheless, its implementation is often suboptimal due to the lack of practicum modules available in the TKE Laboratory. To address this issue, this research aims to design and create a practicum module for a controlled single-phase rectifier, filling the gap in the TKE Laboratory's offerings. The design carried out in this research begins with thyristor selection, control circuit design, mechanical design, and power circuit design. After the design is carried out, it continues with manufacturing and assembly, tool testing, and data analysis. In the practical module testing, this controlled single-phase rectifier uses half waves, with a resistive load (R). The test results of the module that has been created show that this practical module can operate well and produce an output waveform that can be said to be in accordance with theory.

Abstract

The existence of current technological developments can affect education in tertiary institutions because there is a simulator that can make it easier for students to understand electrical circuits, and researchers get a simulator, namely the Proto Circuit Android App. This study aims to reveal the differences in the measurement values in the 3-loop mesh circuit. The 3-loop mesh circuit is a method or method used to analyze an electrical circuit which usually consists of several interconnected loops. At the beginning of the practicum using a simulator called Proto Circuit Android App to make a design or description of a 3-loop mesh electrical circuit in visual form. The ters application is also a very popular and widely used electronic circuit simulation application. However, there is no research that specifically compares the simulation results with the Proto Circuit Android App and physical practice on a 3-loop mesh circuit. Therefore, this study complements this energy by measuring the measurement results of the three methods. The research results show that the results from the simulator and real are quite accurate but there are differences in values caused by imperfections in components, measurement inaccuracies, or other factors that affect circuit performance in real conditions. This research can be used for readers to operate the Proto Circuit Android App simulator and study the 3-loop mesh circuit.
