Abstract

Permintaan energi listrik yang semakin meningkat seiring dengan pertumbuhan populasi dan industrialisasi telah menjadikan pengelolaan sumber daya energi sebagai tantangan utama di berbagai negara. Efisiensi penggunaan daya serta perencanaan yang matang sangat penting untuk memastikan ketersediaan energi yang stabil dan berkelanjutan. Dalam konteks ini, sistem forecasting atau peramalan penggunaan daya harian memainkan peran krusial. Seasonal Autoregressive Integrated Moving Average with Exogenous Regressors (SARIMAX) adalah salah satu metode yang telah terbukti efektif dalam menangani data time series yang kompleks. Metode ini merupakan pengembangan dari model ARIMA (Autoregressive Integrated Moving Average), yang telah digunakan secara luas dalam peramalan data time series. Model ARIMA sendiri merupakan model yang sangat populer dalam analisis time series. Model ini terdiri dari tiga komponen utama: Autoregressive (AR), Integrated (I), dan Moving Average (MA). Penelitian ini bertujuan untuk mengembangkan dan mengimplementasikan sistem forecasting penggunaan daya harian menggunakan metode SARIMAX. Diharapkan penelitian ini dapat memberikan kontribusi signifikan dalam pengelolaan energi yang lebih efisien dan efektif, serta menyediakan dasar yang kuat bagi pengembangan sistem forecasting yang lebih canggih di masa mendatang.

Abstract

The construction of a Solar Power Plant (PLTS) in the Vaname Shrimp Pond, Sungai Kuruk III Village is an efficient solution in overcoming excessive electricity consumption in vaname shrimp cultivation. With the majority of the population working as fishermen and shrimp farmers, shrimp farming requires significant electricity consumption for lights, water pumps and windmills. PLTS is an efficient and sustainable solution by utilizing abundant solar energy in coastal areas. This research uses 28 solar modules with a capacity of 500 Wp, 23 batteries, an inverter with a power of 3,000 watts, and a Solar Charge Controller (SCC) with a capacity of 350 A. Thus, the implementation of PLTS is expected to reduce dependence on PLN electricity while still increasing and maintaining energy productivity as well as maintaining environmental sustainability in vaname shrimp cultivation.

Abstract

Optimal power flow analysis is a calculation to minimize an objective function, namely generation costs or transmission losses by regulating the active power and reactive power generation of each interconnected power system generator by taking into account certain limits. The growth of industrial loads which are dominated by inductive loads requires a fairly large reactive power supply. This reactive power requirement will of course reduce the available power that can be transmitted to the load. Reactive power flow in transmission lines will reduce the active power distribution capacity required by the load. Reactive power flow that is too large can also cause losses. However, this reactive power is also an important component in the stability of the electric power system. For this reason, the flow of active and reactive power in transmission lines needs to be regulated so that the capacity and stability of the electric power transmission system is maintained.

Abstract

Electricity has become an important part of human life along with technological developments in this modern era. Economic progress, quality of life and the business world are very dependent on the electricity supply supplied by PT. PLN (Persero) UP3 Serpong. Electric power distribution is the final stage in the electric power delivery process. This is the process of distributing electric power from the electricity transmission system to electricity consumers. One of the main components in the electric power distribution system is the distribution substation. A distribution substation is an electrical installation device which contains disconnecting, connecting, safety and distribution transformer equipment to distribute electrical power according to consumer needs. Maintenance at distribution substations is carried out to support services to electricity consumers so that the substation equipment used is in reliable condition. and guaranteed continuity. Regular maintenance on distribution substations is important so that distribution substations do not experience damage and disruption while operating.

Abstract

The reliability of the electric power distribution system plays a crucial role in ensuring a stable and continuous power supply to consumers. This study analyzes the performance reliability of the 20 kV distribution network at PT. PLN (Persero) UP3 North Medan by evaluating key reliability indices, including SAIDI (System Average Interruption Duration Index), SAIFI (System Average Interruption Frequency Index), and CAIDI (Customer Average Interruption Duration Index). The research methodology involves data collection from historical outage records, fault analysis, and statistical evaluation of reliability indices. The findings indicate that the reliability performance of the 20 kV distribution network in UP3 North Medan is influenced by various factors, such as equipment failures, weather conditions, and external disturbances. Based on the analysis, strategies for improving reliability are proposed, including preventive maintenance, network automation, and enhanced fault detection systems. By implementing these measures, PLN can improve service quality and reduce power outages, ultimately enhancing customer satisfaction and system efficiency.

Abstract

Some problems occur when the solar cell is connected directly to a battery for charging process. They are caused by the output of solar cell depend on intensity of sunlight. When the intensity reach the maximum value, the current of charging will exceed the permitted current. Therefore, it will shortened the lifetime of the battery. Beside that, when the intensity is droped, the charging process need a long time, moreover it will not performed. This paper investigates the design of charging current monitor that is used as the solution of the problem mentioned above. The system is used for detecting the output current from the solar cells as a charging current monitor following the fluctuation of sunlight intensity. The system use the principal of voltage subtraction and inverting amplifier supported by ATmega 8535 Microcontroller. This paper also investigates about solar cells characterization device which is used to measure the performance of the solar cells.

Abstract

The surface of solar panels plays an important role in the efficiency of solar energy absorption. This study aims to analyze the effect of variations in the surface topography of solar panels on the amount of solar radiation absorbed in the Solar Power Generation (PLTS) system. The method used is experimental by comparing flat, tilted, and optimal horizontal panels under natural lighting conditions. Measurements were carried out with a 50 Wp solar panel for five consecutive days from 08.00 to 16.00 WIB. Data include measurements of voltage, current, power, and energy under three different topographic conditions. The results show that the tilt of the panel according to geographic latitude provides the highest efficiency in solar energy absorption. This study confirms that the design of surface topography can improve the performance of solar panels.

Abstract

Diesel Power Plants (PLTD) are a type of power plant that is widely used in various regions, especially in remote areas that are not yet reached by the PLN electricity network. This research aims to analyze the operation of the PLTD system, including operational efficiency, fuel consumption and its impact on the environment. This analysis uses a general approach based on relevant literature and case studies from several PLTDs in North Sumatra. The research results show that the efficiency of the PLTD system is very dependent on engine maintenance, fuel quality and operational loads. Although PLTD has advantages in terms of flexibility and ignition speed, the main challenges are the high operational costs and exhaust emissions from the PLTD engine.
