Economic dispatch aims to control the variables of the power system so that the power plants can generate maximally based on load demand according to the characteristics of each plant and with cheaper production costs. In this study, economic dispatch is applied to thermal power plants with the integration of Wind Power Plants (PLTB) in Sulselrabar 150kV power system using the Novel Bat Algorithm (NBA) optimization method, considering voltage stability. The generation cost that can be reduced using the NBA method is IDR 12,583,781 per hour compared to the results of the existing system. With the integration of 100% of the PLTB capacity, the NBA method still provides cheaper economic dispatch results. Using the NBA method, the generation cost can be reduced by IDR 29,854,367 compared to the results of the existing system. After the integration of 100% of the PLTB capacity, the power losses obtained are smaller than before the integration of the PLTB. The system bus voltage conditions before and after the integration of the PLTB are also in good condition as they are within the voltage regulation limits set by PLN, which are +5% and -10%

The Effect of Electrical Power Transmission Network Parameters on Short Transmission Line. The transmission system is one of the components of the electrical power operation system where its reliability is crucial. An electrical transmission system has parameters that influence its reliability to function effectively as part of the power system. These parameters include resistance (R), inductance (L), and capacitance (C). This study involves simulations using distribution and transmission trainers to understand the effects of these parameters on the transmission channel. There are three types of electrical transmission channel models based on their lengths. This research focuses on simulating a short 3-phase transmission channel. In the simulation of the short transmission system, two types of simulations were conducted: one with variations in RL load and another with variations in RL load and C load compensation. The results of the first experiment showed that the larger the value of the load L, the higher the value of the receiver voltage (VR) and the higher the value of the receiver side power (PR). In the second experiment, it showed that the larger the value of the load C, the higher the source voltage (VS) and the receiver voltage (VR). Meanwhile, the value of the source current (IS), receiver current (IR), and receiver power (PR) decreased. Additionally, the values of the sending current and the receiving current tend to be the same because the equation stating that the sending current is equal to the receiving current applies. This is due to the variation in the values of the RLC load used. Through the simulation carried out, several data points were obtained that help to understand the relationship between voltage and current, such as load impedance (ZLoad), line impedance (ZLine), voltage regulation (VR), reactive power (Q), apparent power (S), transmitted power (PS), power loss (PLoss), and power transmission efficiency (Ŋ).

Salah satu bentuk energi yang sangat mempengaruhi kehidupan manusia saat ini adalah energi listrik. Kebutuhan akan energi listrik dari masa ke masa semakin lama semakin besar seiringdengan semakin besarnya jumlah penduduk khususnya di Indonesia. PT. PLN (Persero) merupakan penyedia tenaga listrik. Energi angin dapat digunakan untuk berbagai keperluan, termasuk mengedarkan air untuk irigasi, menghasilkan listrik, mengeringkan tanaman, dan memanen. Mengamati pengoperasian turbin angin merupakan langkah awal dalam perancangan, konstruksi, dan pengujian eksperimental turbin angin sumbu horizontal. Pengamatan pengoperasian turbin angin merupakan langkah awal dalam metode perancangan peralatan, pembuatan, dan pelaksanaan pengujian eksperimental turbin angin sumbu horizontal yang digunakan dalam penelitian ini. Penelitian ini fokus pada penyempurnaan turbin PLTB sumbu horizontal yang menggunakan generator BLDC karena kemampuan generator BLDC dapat berfungsi pada putaran per menit (rpm) yang rendah. Penelitian ini banyak mencari referensi untuk apa saja komponen yang digunakan dalam pembangkit listrik tenaga bayu dalam menghasilkan tegangan AC 220V/230V,pengambilan data ketika jarak antara blower dan turbin 1m maka hasil output yang dikeluarkan oleh putaran turbin dapat mencapai 12,1V serta yang dihasilkan oleh inveeter 225V dan pada jarak 1,5m antar turbin dan blower mencapai voltase keluaran yang maksimalnya 11,95Vdan keluaran pada inverter yaitu 210V.

This research aims to design and build a power generation system that utilizes heat from waste combustion using a Peltier thermoelectric module, test the effectiveness of converting heat energy into electricity, and analyze the effect of fuel type and cooling system on device performance. The prototype system uses 12 Peltier modules. In the initial test, the configuration of 2 modules was connected in parallel and 10 modules were connected in series using leaf fuel. Then the Peltier modules were arranged in a full series configuration. The initial test only produced a voltage of 8.1 V at a temperature difference of 80°C. This voltage is considered suboptimal, the system managed to produce a voltage of up to 30 V at a temperature difference of 104°C. This high voltage is then stabilized to 15 V using a linear regulator circuit IC 7815 assisted by a transistor and a 2N3055 capacitor, to maintain output stability before entering the solar charge controller (SCC). The SCC regulates the charging of a 12 V battery, which is then used to supply power to a 500 W inverter to power a 40 W AC lamp. The system is also equipped with an ESP32 microcontroller as a control center, as well as various sensors (current, voltage, temperature) and a 16x2 LCD to display data in real-time. This research shows that the system can efficiently generate electricity from waste incineration and has the potential to be implemented as a small-scale alternative energy solution at Politeknik Bosowa.
