Abstract

Permasalahan krisis energi global dan peningkatan emisi gas rumah kaca telah mendorong berbagai negara untuk mencari solusi energi yang lebih bersih dan berkelanjutan. Kondisi ini menuntut adanya transisi menuju sumber energi yang ramah lingkungan dan efisien secara ekonomi. Penerapan sistem fotovoltaik (PV) yang dikombinasikan dengan sistem penyimpanan energi baterai (BESS) semakin populer sebagai solusi untuk mengurangi emisi karbon dan biaya energi. Penelitian menunjukkan bahwa integrasi BESS dengan PV dapat mengurangi emisi karbon dengan mengoptimalkan penggunaan energi terbarukan dan mengurangi ketergantungan pada pembangkit listrik berbasis fosil. Untuk mengoptimalkan implementasi sistem PV dan BESS, digunakan perangkat lunak Hybrid Optimization Model for Electric Renewables (HOMER) Pro versi 3.14.2, dengan kriteria evaluasi berdasarkan nilai net present cost (NPC) dan cost of energy (CoE) terendah. Hasil simulasi menunjukkan adanya trade-off antara aspek ekonomi dan lingkungan dalam pemilihan konfigurasi sistem energi terbarukan. Konfigurasi off-grid PV–BESS berhasil mengeliminasi emisi karbon dioksida, namun memiliki biaya energi (CoE) 0,365 USD/kWh, yang berarti 60% lebih tinggi dibandingkan konfigurasi hibrida genset–PV–BESS dengan CoE 0,219 USD/kWh dan emisi 55.177 kg CO₂/tahun. Dengan demikian, solusi off-grid PV–BESS lebih unggul dalam aspek keberlanjutan lingkungan, sementara skema hibrida lebih kompetitif secara biaya dan tetap menyediakan keandalan energi melalui cadangan genset.

Abstract

LEDs in lighting systems have been widely used, including public street lighting systems. However, the selection of public street lights in Indonesia often does not use lumen calculations and light dimming technology. This study aims to improve energy consumption efficiency by replacing existing lamps with LED lamps according to the lumen calculation method and using a smart system in the form of automatic dimming of the lamps. The research study was carried out in two stages: the measurement of illumination using a lux meter and the analysis of energy consumption between the existing and the replacement. The replacement scenario is to replace the existing lamps with LED lamps equipped with an automatic dimming system based on lumen calculations. The lighting level is adjusted to Indonesian lighting standards, SNI 7391:2008, 2 to 5 lux. The result of the study is that carrying out a replacement scenario can increase energy consumption efficiency by 77.95%.

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

Two key indicators of a battery management system (BMS) are the state of charge (SoC) and the state of health (SoH). Accurately estimating SoC is important to prevent potential issues. Additionally, space, computing time, and cost are important factors in hardware development. To address these considerations, the first-order extended Kalman filter (EKF) and adaptive extended Kalman filter (AEKF) models were selected due to their simpler data pre-processing and better accuracy. The study recommends using the first-order equivalent circuit model (ECM) method in conjunction with the EKF and AEKF algorithms due to their straightforward setup and efficient computational process. Analysis of the charge-discharge cycles shows that the AEKF method consistently outperformed the EKF method regarding SoC accuracy. Moreover, when given different initial SoC values, the AEKF method displayed superior SoC estimation accuracy compared to the EKF method. Moreover, while the accuracy of the EKF is diminished, the error value remains below 2.5% for up to 500 cycles. Additionally, the shorter computing time of the EKF method is a consideration for practical real-world implementation. Furthermore, experiments conducted over 500 cycles revealed that SoH estimation declined from 99.97% to 76.1947%, suggesting that the battery has reached the end of life (EOL) stage.
