Abstract

Pada zaman ini, listrik sudah menjadi suatu kebutuhan bagi kehidupan manusia. Namun dalam kenyataanya, masih banyak sistem tenaga listrik di Indonesia yang masih belum dapat menyalurkan listrik kepada seluruh penduduk Indonesia. Hal tersebut dapat dibuktikan dari rasio elektrifikasi nasional yaitu masih berada di angka 99,45% pada akhir tahun 2021 dan menargetkan di angka 100% pada tahun 2022. Bahan bakar fosil masih menjadi pilihan terbesar sebagai sumber pembangkitan energi listrik di Indonesia. Salah satu usaha penghematan bahan bakar fosil tersebut ialah dengan memaksimalkan penggunaan EBT sebagai sumber pembangkitan energi listrik. Selain itu, target untuk tercapainya net zero emission tahun 2060 menjadikan pembangkit EBT akan terus ditingkatkan dimana bauran EBT di tahun 2025 mencapai 23% sesuai dengan Rencana Usaha Penyediaan Tenaga Listrik (RUPTL) 2021 – 2060. Tujuan dari penelitian ini adalah studi pengaruh implementasi PLTS dan BESS terhadap kestabilan suatu sistem terisolasi di Indonesia sebagai usaha mengurangi penggunaan pembangkit listrik berbahan bakar fosil dan peningkatan penetrasi pembangkit EBT. Penelitian ini dilakukan menggunakan perangkat lunak DIgSILENT PowerFactory. Hasil analisis aliran daya dan kestabilan sistem menunjukkan bahwa pemasangan PLTS dan BESS pada sistem jaringan terisolasi di Indonesia beroperasi pada tegangan yang aman baik pada waktu beban puncak siang hari ataupun malam hari atau berada pada batas aturan jaringan di Indonesia yaitu ±10% dari tegangan nominalnya. Selain itu sistem pun mampu menjaga nilai frekuensi dan tegangan sistem ketika terjadi gangguan hingga dilakukan tindakan penanggulangan yang ditunjukkan pada nilai tegangan yang berada pada batas nilai tegangan ±10% dari tegangan nominalnya dan nilai frekuensi 50 Hz ± 2,5%. Berdasarkan hasil analisis aliran daya dan stabilitas, rencana pemasangan PLTS dengan BESS pada sistem jaringan terisolasi di Indonesia dapat dilaksanakan dan layak untuk diimpelentasikan

Abstract

The power transformer is one of the leading electrical instruments used to transmit electrical power between generators to adjust the voltage without changing its frequency. Like any other machine, the power transformer will experience degradation over time. High electrical resistance, external factors and environmental temperature could lead to faster degradation. This degradation usually affects transformer isolation material. Degradation of this component furthermore will decrease power transformer efficiency. In 2022, power transformer 3 GI Angke has been used for 28 years, while PT PLN (Persero) has decided that power transformers operating for over 25 years fall into the category of the old machine and need to be replaced. The last asset wellness maintenance data showed that ethane was found in the oil insulation in the second level inspection. The third level inspection also showed degradation of bushing insulation, with the tan delta test result showing the value of 1.28. Asset wellness management is needed in this situation to ensure stability. There are two mitigation options available, to replace some of the components or replace the power transformer altogether. Risk, cost and benefit analysis using a multicriteria approach is used in choosing the best mitigation approach for PT PLN (Persero).

Abstract

The government of Indonesia developing mitigation for climate change and achieving decarbonization in the sea transportation sector by encouraging increased use of onshore power supply for ships when berthing at ports. Off-Grid is one of the green transition technologies that provide great benefits to ports for the mitigation of environmental. To ensure optimal system operation, determining the proper configuration and component sizes is an important decision at the design stage. One of the important activities at the port is the transportation of mining products, B3 waste, and others by using ships operated with diesel engines which are known to be expensive and not environmentally friendly. The configuration consists of a photovoltaic system and an energy storage system as well as land electricity support at the port then optimized by considering solar radiation, temperature, and data component specifications to supply power to the ship so that do not use diesel generators on board. From the calculation results it is known that when the ship is anchored it requires 3,310.34 kWh/day of electrical energy. To meet electricity needs, 3,200 units of PV modules are designed with a power output of 1,216 kW peak and a BESS capacity of 4,064 kWh.

Abstract

Electrical equipment in essential oil processing plants is generally dominated by electric motor loads. In today's digital era, global competition and technological advances encourage factories to increase the efficiency and reliability of their production equipment. One way of efficiency is to use a variable speed drive (VSD). The existence of Profinet technology as a network protocol between the control equipment and the VSD allows users to increase system reliability while increasing energy use efficiency. Even so, there are still many factories that are hesitant to use this technology in their automation systems. Many low to medium-sized factories still use traditional control methods such as hardwired. This method is considered more reliable, and inexpensive compared to using Profinet technology. Cost-benefit analysis is carried out to prove this paradigm. At the same time provides certainty that the investment costs incurred in building the system provide added value for production equipment. From this research, it is proven that the use of Profinet technology in addition to providing savings on investment costs also provides benefits from a technical perspective. This technology also allows the implementation of condition-based monitoring systems for electric motors in production equipment. Which in turn can increase the performance and service life of the machine.

Abstract

As technology develops, the rapid increase in PV capacity will affect the grid. This makes it important to determine the PV limit that can be injected into the grid defined as the PV Hosting Capacity (PVHC). In this paper, the author evaluates and analyses the impact of PV connections on medium voltage distribution lines (20kv) using ETAP 19.01 simulation. A medium voltage Grid with a capacity of 30MVA, has an industrial load varies from 650 kVA to 25 kVA with the total load capacity of 2225 KVA. The loads are supplied from two sources, grid and PV system. The simulation results state that the best of grid performance which provide the best losses and voltage condition when connecting 100% capacity of PV to the existing grid network is by setting the inverter power factor to 0.9. This setting will provide lowest power losses of 0,7 kW and improve the voltage value.

Abstract

The Java-Bali electricity system is the largest electricity system in Indonesia which consists of 5 areas including Jakarta-Banten area, West Java area, Central Java area, East Java area and Bali area. This system is operated to meet the economic, reliability, quality, and green principles. In the case of reliability, one of the essential aims is minimization of transmission losses due to importance in system improvement to increase system operational efficiency to the possible extent. Transmission losses are an inevitable part of the electric power transfer process from generation stations to consumers. The power losses in a transmission line are inversely proportional to the square of the line voltage. This implies that lower line voltages result in higher power losses. Therefore, it is crucial to maintain optimal voltage levels to minimize transmission losses and ensure efficient energy delivery across the power system. One effective way to achieve this is by integrating capacitors into the system. In this study, we have explored two methods that aim to pinpoint the most advantageous locations for the integration of new capacitors. The goal is to optimize capacitor planning, with an emphasis not only on improving voltage levels but also on minimizing transmission losses within the Java-Bali system. The research results indicate that implementing two proposed methods can significantly reduce transmission losses in The Java-Bali system. Method-1 involves identifying the lowest voltage over the course of a year, while Method-2 focuses on the lowest voltage value within the first quartile (Q1/25%) during the same period

Abstract

Energy is a basic human need that has increased in use. Given the limited energy resources, it is necessary to manage energy appropriately and efficiently. Energy efficiency not only has an impact on reducing production costs, but also on reducing emissions. As a concrete step to support the government's net zero emission program by 2060, the company is trying to use alternative biomass fuels, namely: palm kernel shell. The purpose of this study is to conduct a technical and economic analysis of the use of 100 percent palm kernel shells as fuel in a circulation fluidized bed boiler type power plant. This research was conducted at power plant unit 2 of PT XYZ, located in Cilegon, Banten Province. The parameters measured are limited to boiler efficiency, thermal efficiency, and heat rate. The results showed that when using palm kernel shells, boiler efficiency decreased 0.47 percent, thermal efficiency decreased 0.24 percent, and heat rate increased 22 kcal/kWh or 0.76 percent. By considering of three operational parameters (boiler efficiency, thermal efficiency, and heat rate) it can be concluded that technically the use of 100 percent palm kernel shells as fuel in the plant is feasible. There is no major impact on boiler performance regarding the transition of coal to palm kernel shells. The impact of long-term use of palm kernel shells on equipment is beyond the scope of this research.

Abstract

Indonesia has set a target to reduce emissions by 29% or 835 million tons of CO2 by 2030, which was increased to 32% or 912 million tons of CO2 in 2023. The building sector is one of the largest contributors to emissions in Indonesia. To reduce these emissions, the Indonesian government has issued energy conservation regulations requiring each sector to reduce energy consumption. According to Government Regulation No. 33 of 2023, energy conservation is mandatory for energy users in the building sector who use energy sources equivalent to or greater than 500 Tons of Oil Equivalent. One way to conserve energy is by implementing energy-efficient technologies, without compromising the comfort of building users, which includes thermal and visual comfort as part of indoor environmental quality (IEQ). An energy-efficient technology using the Evolution Mating Algorithm (EMA) is proposed. This study will discuss energy use without compromising building user comfort in tropical countries using the EMA optimization algorithm. The study demonstrates that EMA successfully optimizes energy use without reducing user comfort in tropical countries.
