Abstract

Batteries are an essential product for alternative energy, required for various electronic devices and everyday human needs. Rechargeable batteries must be carefully managed to avoid quick damage due to improper charging systems or poor-quality chargers. Charging a 12V battery is done by continuously flowing current until the battery voltage reaches its specified value. As technology advances, many battery chargers are available on the market, using either high or low frequencies. By comparing the measurement results of high-frequency charging systems (using MOSFET and switching) and low-frequency systems (using transformers), we can draw conclusions that demonstrate the performance and quality of charging in these different systems.

Abstract

Lithium-ion (Li-ion) batteries are one of the battery technologies widely used in electric motorcycles (EVs) because they have high efficiency and good durability. This battery functions as the main energy source for electric vehicles and is an important component in supporting vehicle performance. This study aims to analyze the characteristics of Lithium-ion batteries in electric motorcycles by considering factors such as operating temperature, voltage, and the influence of speed and terrain. Tests were carried out on flat and uphill tracks with speed variations of 10 km/h, 30 km/h, and 50 km/h. The results showed that Lithium-ion batteries tend to experience a faster increase in temperature when used at high speeds, but the battery voltage remains stable during the Discharge and Charging process without any significant spikes. These findings provide insight into the performance of Lithium-ion batteries in electric vehicles, as well as the importance of temperature management to maintain optimal battery performance.

Abstract

Power system stability is a critical factor in maintaining the continuity and quality of energy supply, especially in transmission systems that face load fluctuations and integration of renewable energy sources. The main problems in this study are voltage instability and reactive power oscillations that often occur due to disturbances such as sudden load changes or short circuits, as well as the limited capacity of conventional controllers in reducing these impacts. This study aims to explore the role of Static VAR Compensator (SVC) as part of Flexible AC Transmission Systems (FACTS) technology in improving transmission system stability through a qualitative approach. The research method is carried out with descriptive analysis based on literature studies, mathematical modeling of the power system, and numerical simulations to understand the dynamics of the system response to disturbances. The focus is given to qualitative evaluation of the interaction between SVC, system parameters (voltage, reactive power, and phase angle), and the impact of controller placement on network reliability. Simulation case studies cover small to large disturbance scenarios to assess the effectiveness of SVC in restoring stability. The results show that SVC integration makes a significant contribution to improving the dynamic stability of the transmission system. Qualitative analysis finds that SVC is able to reduce voltage oscillations and accelerate post-disturbance system recovery through adaptive reactive power regulation. However, the limited capacity of SVC in handling extreme disturbances indicates the need for combination with other FACTS controllers (such as STATCOM or UPFC) for more complex systems. This study also reveals the importance of proper SVC placement strategy to optimize its effectiveness.

Abstract

Measuring and Limiting Devices (APP) or kWh meters have a very significant role in securing PT.PLN (Persero) income. kWh Meter acts as a transaction point between PT.PLN (Persero) as a producer and customers as consumers, therefore the accuracy of the kWh Meter in measuring energy consumption used by customers plays an important role as company income, because from all PT.PLN (Persero) business processes from generation, transmission, to distribution, only energy measured in the customer's kWh Meter will be the electricity bill that must be paid by the customer as a consumer to PT.PLN (Persero) as a producer. To obtain real measurement results with good quality, consistent preparation and evaluation are needed in its implementation, if not implemented properly it will result in losses for the company in the form of losses caused by the kWh Meter being jammed or damaged and still installed at the customer's transaction point. Therefore, APP must be managed properly and correctly by competent and highly dedicated officers. APP maintenance is carried out with the aim of avoiding measurement discrepancies by APP which ultimately cause excess or shortage of bills.
