Stability Analysis of Electric Power Systems Using Controllers Facts on Transmission System
Full text linkPower 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

Analysis of Frequency and Voltage Stabilization Control in Low-Inertia Power Systems Using a Boost Converter
Full text linkLow-inertia power systems, especially those based on renewable energy sources such as solar and wind, face major challenges in maintaining frequency and voltage stability. The absence of mechanical inertia in these systems, which is usually available in synchronous generators, makes the system more vulnerable to load changes or network disturbances. Therefore, an effective control method is needed to maintain such stability. This study analysed the frequency and voltage stability control of low-inertia power systems using a Boost Converter. A Boost Converter is used to regulate and stabilize the output voltage of a fluctuating power source, such as a solar panel, by increasing the unstable input voltage. Meanwhile, a frequency control method such as is implemented to imitate mechanical inertia, thus maintaining the frequency at a desired value. The results show that the use of a Boost Converter effectively improves voltage stability, while a VSG-based frequency control strategy successfully imitates the inertia response of a synchronous generator, maintaining a stable frequency despite the system having low inertia. Thus, the combination of these two methods can improve the reliability of low-inertia power systems, especially in applications utilizing renewable energy sources
Application Of The AHP Method In A Decision Support System For Used Car Selection Recommendations
Full text linkThe selection of used cars often becomes a complicated matter for consumers who lack knowledge about cars. According to the owner of the Mobilku Sumut Aceh showroom, many aspects need to be considered, such as engine condition, year of manufacture, price, and physical condition.

The AHP method was chosen for its ability to break down complex problems into a hierarchical structure and compare criteria pairwise to determine priority weights. This analysis allows consumers to adjust their preferences for specific criteria, such as budget or specific features. Based on testing results, this analysis is capable of providing recommendations that match the needs and preferences of consumers, thereby helping them make more targeted and effective decisions. This study is expected to simplify the decision-making process for purchasing used cars for consumers at the Mobilku Sumut Aceh showroom
Analysis Of Results Of Voltage Transformer Insulation Resistance Test On Bay Banda Aceh 1 And Bay Banda Aceh 2 Conductors At Ulee Kareng Substation
Full text linkVoltage transformers are one of the important components in an electric power system that functions to reduce the voltage from the transmission network to a lower level for measurement and protection purposes. The quality of the insulation of the voltage transformer greatly affects the reliability of the operation of the electric power system. Therefore, periodic insulation resistance testing is needed to ensure optimal insulation performance and avoid electrical interference. This study aims to analyze the results of the insulation resistance test on the voltage transformer used in the Bay Banda Aceh 1 and Bay Banda Aceh 2 conductors at the Ulee Kareng Substation. The test was carried out using a megger test tool with a method of measuring the insulation resistance between the primary winding and the ground and between the primary winding and the secondary. The measurement data were compared with applicable standards to determine the insulation condition of the voltage transformer. The results of the study showed that the insulation resistance values obtained from both conductors had variations that were influenced by environmental factors such as temperature and humidity. Based on the analysis carried out, most of the test results were still within safe limits according to IEEE and SPLN standards. However, there were several test values that were close to the minimum limit, which indicated insulation degradation that needed further attention. With this research, it is expected to provide information on the condition of voltage transformer insulation and recommendations for preventive actions needed to maintain the reliability of the electric power system at the Ulee Kareng Substation
