Abstract

Solar-powered electric vehicle (EV) charging stations are essential in advancing low-carbon transportation. However, determining optimal locations remains challenging due to spatial, technical, and environmental constraints. This systematic review, conducted under the PRISMA 2020 framework, synthesizes optimization techniques for siting solar-powered EV charging stations from 15 peer-reviewed studies published between 2016 and 2024. The reviewed methods are classified into five major categories: geographic information systems (GIS)-based spatial models, multi-criteria decision-making (MCDM) frameworks, hybrid approaches integrating fuzzy logic and GIS, heuristic/metaheuristic algorithms such as genetic algorithm (GA) and particle swarm optimization (PSO), and artificial-intelligence-based models for predictive site selection. GIS-MCDM hybrid approaches were the most prevalent, offering improved robustness in spatial decision-making. Nevertheless, the literature reveals persistent gaps, including limited empirical validation, insufficient use of real-time data, and weak integration with smart-grid planning. This review provides a structured methodological classification, highlights sustainability considerations, and outlines a research roadmap toward intelligent, data-driven, and sustainable EV infrastructure planning aligned with global energy-transition goals.

Abstract

Inverter-based Heating, Ventilation, and Air Conditioning (HVAC) systems are increasingly utilized in industrial settings for their superior energy efficiency and controllability. Despite these advantages, nonlinear switching in inverters generates significant harmonic distortion, particularly at lower-order frequencies such as the 3rd and 5th, which can compromise power quality, reduce system lifespan, and lead to non-compliance with regulatory standards. This study proposes a hybrid passive filter solution—combining a Double Tuned Filter (DTF) and a High Pass Filter (HPF)—to mitigate harmonic distortion in an industrial HVAC system. Field data collected using a Power Quality Analyzer (PQA) revealed a 3rd-order Individual Harmonic Distortion of Current (IHDi) of 12.9%, far exceeding the 4.0% threshold specified in IEEE 519:2022. The hybrid filter was analytically designed and validated through MATLAB/Simulink simulation. Post-simulation results demonstrated effective mitigation of Total Harmonic Distortion (THD) to 3.45%, with the 3rd-order IHDi mitigated to 3.42%, achieving full compliance with IEEE 519:2022. Furthermore, the hybrid filter preserved voltage waveform quality and suppressed high-order harmonics without incurring additional energy losses or resonance issues. The combination of DTF and HPF offers wide-spectrum harmonic mitigation and enhanced power system stability. This solution is well-suited for high-load, scalable infrastructures aligned with Industry 4.0 requirements. The study concludes that passive hybrid filters are a reliable and cost-effective strategy for harmonic suppression, and future work should explore real-time adaptive control and hybrid active-passive configurations for enhanced dynamic performance

Abstract

The insulation condition of high-voltage equipment can be determined by measuring partial discharge (PD), which is an important indicator in insulation degradation. One of the PD detection methods that can be used is to use antennas as sensors in detecting electromagnetic waves generated from PD activities, especially in gas insulated switchgear (GIS) systems. This study focuses on designing and testing dipole antennas in the ultra-high frequency (UHF) frequency range of 300 Mhz-3 GHz to detect PD signals in GIS. Previous studies on dipole antennas with dimensions of 66×15 mm have reported a bandwidth of 336 MHz and a return loss of -22.4 dB at 1.3 GHz. The antenna was fabricated using an FR4-epoxy substrate with a thickness of 1.6 mm, a substrate radius of 102 mm, and a gap distance of 2 mm. Optimization of the antenna length and width significantly improved performance characteristics. Simulation results show that a dipole antenna with dimensions of 35×40 mm antenna produced a wider bandwidth of 989 MHz with a return loss of −28.47 dB at 1.4 GHz. Experimental validation using vector network analyzer (VNA) and PD testing on GIS confirmed that the optimized dipole antenna effectively detected PD activity at a voltage level of 16 kV.

Abstract

Distributed photovoltaic (PV) generation has emerged as a key solution for enhancing the performance of medium-voltage (MV) distribution networks, particularly in isolated systems with limited conventional generation. This study investigates the impact of centralized and distributed PV integration on voltage profile and power losses in the 20 kV East Sumba distribution system. A steady-state load flow analysis using the Newton–Raphson method was performed in DIgSILENT PowerFactory under three PV penetration levels (20%, 50%, and 100% of peak load). The base-case condition shows significant undervoltage at remote buses and total active power losses of 474.47 kW, mainly due to long radial feeders and concentrated loading. The results indicate that centralized PV placement yields the strongest voltage recovery near the interconnection point at 100% penetration, whereas the minimum system power loss is achieved at 50% penetration. By contrast, distributed PV placement provides more uniform voltage support across remote buses, although with lower effectiveness in reducing total system losses. These findings reveal a clear operational trade-off between voltage improvement and loss minimization, implying that the preferred PV placement strategy should be selected according to the specific technical objective of the network. This study provides practical insights for planning and optimizing PV integration in weak and isolated MV distribution systems.

Higher education institutions play a vital role in adopting and promoting clean energy technologies. This research aims to plan the implementation of a solar power generation system (PLTS) at Siliwangi University Campus II Mugasari using Helioscope software-based simulation. The research methodology includes topographical analysis of the location, evaluation of solar energy potential, and optimization of system design to maximize efficiency and energy output. Helioscope was chosen for its ability to model photovoltaic systems by considering critical variables such as solar radiation, panel configuration, and specific location characteristics. Simulation results indicate that the designed PLTS system has significant potential in generating electrical energy and contributing to the reduction of greenhouse gas emissions. Quantitative analysis includes estimates of energy production capacity, optimal configuration of photovoltaic arrays, and long-term system performance projections. This research provides a comprehensive blueprint for developing renewable energy infrastructure in the campus environment. Additionally, this study contributes to the body of knowledge related to the integration of solar technology in academic contexts and can serve as a replicable model for other higher education institutions in transitioning towards more sustainable and environmentally friendly campuses.

Abstract

Distribution transformers play an important role in ensuring the continuity of electrical energy distribution, so an accurate diagnostic method is needed to detect damage. This study aims to analyze the condition of a 250 kVA UNINDO brand distribution transformer using a multi-parameter approach through Transformer Turns Ratio (TTR), Insulation Resistance (IR), and visual inspection tests. TTR testing was carried out at seven tap positions, while IR testing used a voltage of 5 kV. The results showed that phases A and B were still within the tolerance limit of ±1%, while phase C did not show a ratio reading indicating open winding. Very low insulation resistance values (0.02-0.05 MΩ) indicated significant insulation degradation. These findings were reinforced by visual inspections that showed physical damage and indications of overheating in the phase C winding. This study confirmed that the integration of TTR, IR, and visual inspection methods was able to improve the accuracy of transformer damage diagnosis and support condition-based maintenance decision making in the field.

Abstract

Pekerjaan Dalam Keadaan Bertegangan (PDKB) merupakan strategi utama PT PLN dalam menjaga keandalan pasokan listrik tanpa pemadaman, namun aktivitas ini memiliki tingkat bahaya yang tinggi akibat paparan langsung tegangan menengah serta pekerjaan di ketinggian. Penelitian ini bertujuan menganalisis risiko keselamatan dan kesehatan kerja (K3) pada kegiatan bongkar pasang Load Break Switch (LBS) oleh tim PDKB PLN UP3 Tasikmalaya menggunakan metode Hazard and Operability Study (HAZOP). Analisis dilakukan terhadap 27 aktivitas kerja dengan menilai tingkat risiko berdasarkan kombinasi likelihood dan consequences. Hasil penelitian menunjukkan bahwa sebagian besar risiko terkonsentrasi pada fase tengah pekerjaan, khususnya aktivitas yang melibatkan switching, pemeliharaan peralatan bertegangan aktif, dan pekerjaan di ketinggian, dengan potensi dampak cedera fatal akibat sengatan listrik dan jatuh. Temuan ini menegaskan bahwa tingginya nilai risiko tidak semata dipengaruhi oleh probabilitas kejadian, melainkan oleh besarnya tingkat keparahan dampak. Hasil studi ini memberikan kontribusi praktis berupa dasar penentuan prioritas mitigasi risiko, khususnya pada penguatan prosedur kerja, pengawasan ketat pada fase kritis, dan peningkatan disiplin penggunaan alat pelindung diri bagi unit PDKB PLN.

Abstract

This Distribution transformers are essential devices in electrical networks, transferring power from transmission lines to consumers at usable voltage levels. Their reliability is closely linked to the condition of the insulation system, primarily composed of mineral oil and cellulose paper, which are highly sensitive to moisture. To reduce water absorption, an oven drying process is applied, improving both insulation resistance and oil breakdown voltage. This study investigates the efficiency of the oven drying process at PT Harifff Power Services using a case study approach. Data were collected through direct observation, insulation resistance testing, oil breakdown voltage measurement, and interviews with field technicians. Findings reveal that the drying process took between 7 and 14 days, significantly longer than the 1–2 days recommended in literature at 100–120 °C. The main limitation is the absence of an automatic temperature control system in the vacuum oven, leading to inefficiency. Nevertheless, post-drying measurements indicate improved insulation quality. It is therefore recommended to upgrade the oven with temperature control and to optimize storage procedures to achieve greater efficiency and extend the lifespan of distribution transformers.

Abstract

The rapid growth of electric vehicle (EV) adoption has increased the need for reliable public charging infrastructure in urban areas. In Indonesia, public charging stations are generally supplied by grid electricity (PLN), which may increase operational costs and emissions depending on the grid generation mix. Integrating solar photovoltaic (PV) into electric vehicle charging stations (EVCS) offers a cleaner option. however, it requires careful consideration of both spatial suitability and techno-economic feasibility at the planning stage. This study proposes an integrated GIS-based planning framework to identify priority areas for solar-powered public EV charging stations in Denpasar City, Indonesia. The approach combines GIS-based spatial suitability analysis and comparative techno-economic evaluation within a unified planning workflow. Spatial analysis is first applied to screen candidate zones based on accessibility, land use compatibility, population density, proximity to activity centers, and solar energy potential. Subsequently, a techno-economic assessment is conducted to evaluate the feasibility of renewable energy–powered EV charging systems in the shortlisted areas. The results indicate that central urban areas and commercial districts emerge as priority deployment zones, driven by high accessibility, stronger demand indicators, and favorable techno-economic characteristics. Mixed-use residential areas are identified as complementary options to expand service coverage, while peripheral and agricultural-dominated areas show limited suitability for early deployment. The proposed framework demonstrates how integrating spatial screening and techno-economic considerations within a planning-oriented workflow can support more informed decision-making for sustainable EV charging infrastructure development in urban environments.
