Abstract

 Based on the Decree of the Minister of Energy and Mineral Resources (ESDM) Number 0074.K / 21 / MEM / 2015 concerning the Ratification of the 2016-2025 Electricity Supply Business Plan (RUPTL), the load growth every year has increased. Therefore, there will be additional Generating Units with a capacity of 1000 MW at PLTU Paiton, it is necessary to analyze the effect of additional loads in 2017 - 2022 on the 500 KV GITET system before and after the addition of a 1000 MW generator. Based on the analysis, it is known that the additional power of 1000 MW will strengthen the Paiton GITET reserve margin in bearing the load growth, it can be seen from the reserve margin value before the addition of power plants by 16% and after the addition of 29%. For the ability of the Paiton - Grati GITET transmission line until 2022, the load is 62% with a power loss of 35.41 MW (2.85%) and the load on the Paiton - Kediri GITET transmission line is 62% with a power loss of 35.41 MW (2.85%) indicates that the channel still in good shape. In addition, the load condition for the IBT transformer until 2022 is 84%, it can be concluded that the transformer is in good condition

Abstract

The length of conductor paths in distribution networks often leads to voltage drop issues and significant network losses. Placing capacitor banks in the distribution network is the primary solution to address these problems. However, optimizing the installation to achieve a significant impact on the voltage level in the network requires complex calculations, especially for very long lines such as in the 20 kV medium voltage network. This paper will use a 20 kV primary distribution system with 10 buses and 9 lines. Based on operational conditions, there are several issues that need to be addressed, and their solutions will be sought through heuristic methods.

Abstract

The central government has established the National Energy Policy (KEN) to increase the utilization of renewable energy sources (EBT) by around 23% by 2025 and 31% by 2050. In an effort to support the government's program, researchers have developed a Thermoelectric Generator (TEG) as an alternative power supply to replace the energy source from PT PLN for electrical equipment used in the green bean germination process such as lights, fans, and water pumps. This prototype consists of two chambers: a combustion chamber that generates electrical energy and a control room for the germination process. These two areas are separated to ensure that the control device and germination process are not affected by the heat from combustion. The main components of this prototype include ten TEG units with a maximum power of 5.2 W, a 33 Ah battery, an 8A Buck-boost converter, a 3A Buck converter, a 6W Full Spectrum LED, four DC fans, and a DC pump. The TEG functions effectively as the germination process proceeds smoothly.

Abstract

The Galunggung feeder has a total line length of 10.68 kilometers and is supplied by power transformer number 1 at the Polehan substation, with a capacity of 30 MVA. As of December 2020, the peak load on the Galunggung feeder was recorded at 231.4 A, while the lowest load was 133.9 A. Up to the current condition, the Galunggung feeder is operating within standard parameters, with a voltage drop of 0.434 kV or 2.17%. However, it is possible that with future developments and an increase in the number of customers over the years, the energy demand will also increase. Due to this additional energy demand, the protection system may require adjustments to accommodate the increased load.After conducting load forecasting using simple linear regression, a forecast for the next 10 years was obtained. In the year 2030, it is anticipated that the Galunggung feeder will experience a 24% increase in load. With this load increase and no changes to transformers or conductors, there will be no alterations to impedance and short-circuit current calculations. Therefore, no protection setting adjustments are necessary. The recommended action would be to upgrade some transformers that are approaching their capacity limits.
