Abstract

Network maneuvers in the medium voltage distribution system are performed during faults or maintenance to maintain continuity of electricity service. This study focuses on analyzing the network conditions during maneuvers in the Tasikmalaya area to identify the optimal feeder backup strategy and minimize voltage drops and power losses. The analysis was conducted using ETAP software with simulations of various load scenarios (40%, 80%, and 100%). The results show that the best voltage in the existing condition is found on the SBBC feeder, with a voltage value of 0.9710 p.u at a 100% load condition. Meanwhile, the smallest power losses occur on the TMSR feeder, amounting to 233.6 kW. In the maneuver scenario, the best results are obtained when the TMSR feeder is backed up by the PDYN feeder through the LBS RIMA switch, with a voltage of 0.9612 p.u on the TMSR feeder and 0.9533 p.u on the PDYN feeder, and total power losses of 606.6 kW. This study highlights the importance of in-depth analysis in selecting maneuver strategies to ensure network stability and minimize service disruptions. The decision to choose a backup feeder should not only consider the feeder's ability to support additional loads but also its impact on power losses and voltage quality across the network. Therefore, this research makes a significant contribution to more efficient medium voltage distribution network management, particularly in handling faults and maintenance.

Abstract

This study presents a comprehensive techno-economic planning of an On-Grid Photovoltaic Power Plant (PV PP) system for Plaza Asia Tasikmalaya by utilizing the HOMER (Hybrid Optimization Model for Multiple Energy Resources) software. The main objective is to develop an optimized PV system configuration based on actual load profiles and solar radiation data, without focusing on physical implementation or post-installation impacts. The planning process includes site-specific energy demand analysis, assessment of solar potential using satellite-derived datasets, and the selection of system components such as photovoltaic panels, battery storage, and inverters. Field observations and documentation were conducted to collect primary and secondary data regarding electricity consumption trends, solar irradiance levels, and component specifications and prices. The simulation using HOMER indicates that the optimal system configuration comprises 1,894 units of 340 Wp monocrystalline solar panels, 102 EnerSys PowerSafe SBS 1800 battery units (248 kWh), and 50 SolaX X3-Hybrid10 inverters rated at 10 kW. The system is projected to generate 902,334 kWh annually, supplying approximately 62.1% of the total electricity consumption of the building. The remaining demand is met by the PLN grid, especially during periods of low irradiance or peak loads. The simulation yields key performance indicators including Net Present Cost (NPC), Initial Capital Cost, and Levelized Cost of Energy (COE), which are calculated by HOMER using discounted cash flow principles. These indicators are crucial in evaluating the technical and financial feasibility of the planned configuration. By focusing on accurate simulation, real-world data inputs, and economically viable system design, this study contributes a replicable planning approach for renewable energy integration in commercial buildings. It also highlights the importance of using simulation tools like HOMER in supporting investment planning, technology selection, and policy formulation related to on-grid solar energy systems. The findings may serve as a technical reference for future energy planning in similar commercial settings across regions with comparable solar resources.

Abstract

Abstract. This study investigates the impact of speed variation on the performance of a Permanent Magnet Synchronous Generator (PMSG) configured with 12 slots and 8 poles (12S8P) for wind energy conversion systems. PMSG has gained attention due to its high efficiency, simple design, and ability to operate effectively at low speeds, making it particularly suitable for renewable energy applications like wind turbines. Using MagNet simulation software, the performance of the PMSG was analyzed over a speed range of 1000–6000 rpm and load variations of 10–50 ohms. The results showed a maximum magnetic flux of 0.000927 Wb, while the no-load average voltage was 17.78 V at a speed of 1000 rpm. Furthermore, it was observed that voltage and current increased proportionally with speed. Optimal torque performance was achieved at a 30-ohm load at a speed of 5000 rpm, highlighting the importance of load optimization for effective energy conversion. Efficiency analysis revealed that the generator achieved its highest efficiency of 92.96% at a 10-ohm load and a speed of 5000 rpm. This study also emphasizes the influence of material properties, slot-pole design, and load conditions on generator performance. These findings provide critical insights for the design and optimization of wind turbines, particularly in regions with varying wind speeds. Moreover, this research contributes to advancing the utilization of renewable energy technologies by offering data-driven strategies for enhancing system efficiency and reliability..

Abstract

The utilization of solar energy through photovoltaic (PV) technology continues to evolve as a promising renewable energy source. However, the efficiency of solar panels remains limited by heat generated during operation, causing performance degradation as temperature rises. This phenomenon presents a major challenge in optimizing PV technology. This research aims to enhance the efficiency of photovoltaic systems by incorporating Thermoelectric Generator (TEG) modules, resulting in an innovative hybrid Photovoltaic-Thermoelectric Generator (PV-TEG) system. The PV-TEG hybrid system is designed to harness excess heat produced by solar panels, which is then converted into additional electrical energy through TEG modules, utilizing the Seebeck effect. In this experimental study, two heat transfer methods were tested and compared: Micro-Channel Heat Pipe (MCHP) and copper plate. Both methods were evaluated to enhance the temperature gradient across the TEG modules, with the goal of optimizing the hybrid system's performance. The research methodology included design, fabrication, and testing of PV-TEG hybrid system prototypes under various controlled environmental conditions. Measured parameters included operational temperature, output voltage, current, and total power generated. Thermodynamic and electrical analyses were conducted to evaluate energy conversion efficiency and overall system performance. Test results showed that the PV-TEG hybrid system could increase overall efficiency by up to 10% compared to conventional solar panels. The use of copper plates as heat transfer media resulted in higher efficiency compared to MCHP, indicating greater potential for practical implementation. Economic analysis also demonstrated the long-term feasibility of this hybrid system, despite higher initial costs.In conclusion, the developed PV-TEG hybrid system makes a significant contribution to improving the energy efficiency of solar panels.

Abstract

The need for electrical energy in Indonesia is increasing, while dependence on fossil fuels remains dominant. One potential alternative is the utilization of solar energy through rooftop Solar Power Plants (PLTS). This study aims to design a rooftop PLTS system in the Integrated Classroom and Laboratory Building, Campus 1, Siliwangi University with a technical and economic approach. The research method includes collecting data on load profiles and potential solar radiation, designing system capacity, selecting main components, and simulating using PVsyst software to obtain estimates of energy production and system performance. The planning results show a design capacity of 71,107 Wp with a configuration of 118 solar panels with a capacity of 600 Wp, which produces energy production of around 299–318 kWh per day or equivalent to 109–116 MWh per year. The PVsyst simulation produces an average Performance Ratio value of around 80%, which is in the good category. However, the economic analysis using the Net Present Value (NPV) method shows a negative value (−996,310,000), so this project is not yet financially feasible if implemented in a fully off-grid scenario. In conclusion, the implementation of rooftop solar power plants in the Integrated Classroom and Laboratory Building, Campus 1, Siliwangi University is technically feasible, but not yet financially feasible under current conditions. Therefore, it is recommended to implement a hybrid or on-grid scenario, as well as an electricity tariff sensitivity analysis to increase economic feasibility.

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
