Abstract

This study presents a detailed simulation of lithium-ion battery charging using the Constant Current/Constant Voltage (CC/CV) method. MATLAB is used in conjunction with certain mathematical algorithms, such as numerical integration and curve fitting, to simulate the charging process, utilizing parameters including a constant current of 1C and a voltage threshold of 4.2V. The simulation analyzes the charging efficiency, usable capacity, and internal impedance variation under various current levels and voltage thresholds. The CC/CV method is compared with findings from other studies that also used the CC/CV charging technique, highlighting similarities and differences in the results. This analysis reveals that while CC/CV is effective in balancing charging speed and safety, minimizing the risk of overcharging, some studies note challenges related to temperature variations and their impact on battery performance. While CC/CV offers optimal management for lithium-ion battery charging, future research can focus on investigating the long-term effects of CC/CV on battery life under various environmental conditions, considering the findings and methodologies of similar studies.

Abstract

The 3-phase induction motor is an electric motor with a strong, reliable, and easy-to-operate construction, and it is cheaper compared to other types of electric motors, making it widely used by the public. Although this motor is considered reliable, it still has some drawbacks, such as low performance, including starting torque, power factor, and efficiency compared to other types of electric motors. Therefore, research to improve the performance of this motor is ongoing. This paper aims to outline some methods that have been used by previous researchers to improve the performance of induction motors based on literature studies. Some of the methods discussed in this paper include the use of permanent magnets on the rotor, operating the 3-phase induction motor on a single-phase system, developing ferromagnetic materials for the motor, increasing the number of coil phases, and optimizing coil design in the motor. The advantages and disadvantages of using these methods to improve motor performance are briefly outlined.

Abstract

The need for electrical energy is changing and increasing, requiring system flexibility always to be changed and developed. On the other hand, changes in the configuration of the electric power system due to the addition of components or sub-systems also change system parameters such as impedance or level of fault current (short circuit current). This paper presents a study of changes in the fault current caused by adding a new generating bus to an electric power system. This paper aims to determine the change in short-circuit current due to the addition of generators on new buses connected to existing buses to identify the most suitable location for adding these generators based on short-circuit current levels. Three-phase short circuit faults are simulated and analyzed on the IEEE 14 bus standard system using ETAP software with a base MVA 615 MVA. The addition of generators was carried out at five locations with varying generating capacities. The research results show that the short circuit current will change significantly when adding a generator bus to bus 13, with an average percentage change of 5,656%. The smallest change occurs when adding a generator to bus 2, with an average percentage change of 2,417%. The research results conclude that connecting a generator to a new bus linked to an existing generator bus (PV bus) is more effective than connecting it to a new bus associated with a load bus (PQ bus).

Abstract

This research examines the impact of interruptions in electricity supply on the production of small and medium enterprises in West Sumatra from 2014 to 2021. The data used in the research was obtained from the Ministry of Trade and Industry of West Sumatra, including the production variables, employment, investment, and other variables that influence the production activities. A regression equation connecting production factors and production levels is formulated. Furthermore, another regression equation is also formulated by considering the electricity interruption factor, namely the SAIDI index on production levels. The effect of electrical power interruptions is then evaluated by comparing the two equations. The research results show that the most significant production loss occurred in 2019, 16.07 hours/year, while the most negligible loss occurred in 2015, 6.53 hours/year. Trend data collected during the research period regarding loss conditions and interruption parameters shows that electricity disturbances do not have a linear impact on production losses. The research also shows that electric power does not significantly impact the production activities of small and medium enterprises in West Sumatra.
