Abstract

Seiring dengan pertambahan beban, PLN mengimbanginya dengan cara membangun pembangkit baru. Hal tersebut dapat menyebabkan kontingensi tegangan dikarenakan perubahan aliran pada jaringan yang dapat menyebabkan pemadaman listrik. Peralatan Flexible AC Transmission System (FACTS) yang membantu mengatasi permasalahan kontingensi tegangan. Salah satu peralatan FACTS adalah Thyrisitor Controlled Series Compensator (TCSC). Karena performa TCSC bergantung pada lokasi pemasangan dan penentuan besar kapasitas TCSC diperlukan pemasangan dan penentuan ukuran TCSC yang optimal. Metode yang diajukan adalah dengan menggunakan Fast Voltage Stability Index (FVSI) sebagai acuan lokasi pemasangan TCSC. FVSI adalah salah satu metode untuk menentukan indikator index stabilitas tegangan. Untuk ukuran TCSC ditentukan dengan menggunakan metode trial and error. Metode tersebut akan diujikan pada jaringan transmisi 150 kV di Kalimantan Selatan-Tengah Tahun 2019 yang mengacu pada RUPTL. Dari hasil simulasi membuktikan peningkatan kestabilan tegangan dengan penambahan TCSC pada jaringan.

Abstract

Distributed Generator (DG) merupakan pembangkit berkapasitas kecil yang terletak pada sistem distribusi tenaga listrik dan biasanya ditempatkan pada bus-bus yang terhubung langsung ke beban. Parameter-parameter yang perlu diperhatikan dalam pemasangan DG antara lain level tegangan dan kerugian daya. Artificial Bee Colony (ABC) merupakan kecerdasan buatan yang menirukan perilaku sekumpulan lebah dalam mencari sari bunga (nectar). Pada tugas akhir ini dilakukan optimisasi penentuan letak dan kapasitas optimal DG dengan menggunakan algoritma ABC pada sistem distribusi radial IEEE 33 bus. Simulasi dilakukan menggunakan software MATLAB. Dari hasil simulasi yang diperoleh, pemasangan DG pada sistem distribusi dapat menaikkan level tegangan pada tiap bus dan mengurangi total kerugian daya pada sistem.

Abstract

Bagan tancap is a conventional fishing using diesel as its main source. This conventional method needs to be replaced with an eco-friendly and easy to use system, namely solar panels. The solar panels power is just limited by time so the stability of the system is poorly maintained that needs to be a battery as a storage of energy to improve system stability. However, the power that is not optimal causes the charging battery to take longer and not be constant with periods of weather and irradiation coditions. The charging battery without MPPT it tends not to be optimal because the solar panel does not operate at its maximum value. MPPT with perturb and observe algorithms can maximize power on solar cells with tracking speeds that depend on the response speed of the converter. While boost coverter has the ability to maintain potential differences that are tailored to the battery specifications and keep the current and voltage ripple values relatively small. For this reason, this final project will design and implement solar charge controller equipped with MPPT P & O (Perturb and Observe) and boost converter, this method can maximize the power of the solar panel by 97.84% with a faster charging time for 27 minutes.Keywords: light fishing, MPPT, perturb and observe, solar charge controller.

Abstract

This paper proposes a method of maximum power point tracking control using Incremental Conductance employed in hybrid photovoltaic-wind turbine for DC micro-grid system. The rapid growth of renewable energy using photovoltaic (PV) and wind turbine due to low operational cost and easy to implementation. Improvement of the efficiency of PV and wind turbine based on incremental conductance is the solution to get maximum power in PV and Wind Turbine. The proposed method uses variable step to achieve maximum power with high speed tracking, high efficiency and low steady state error calculation. The performance of the MPPT technique has been applied in dc-dc boost converter. Moreover, Zeta Converter using Coupled Inductor-Capacitor is added for maintain constant voltage in passive load. This high gain converter can reach 311 Volt DC with 1000 W output power and high efficiency up to 90%. The effectiveness of proposed method is implemented in two hybrid system using PV and wind turbine source. Keywords: incremental conductance technique; maximum power point tracking; Zeta Converter using Coupled Inductor-Capacitor.

Abstract

Transient stability is an important aspect in maintaining the continuity and reliability of the electrical power system when a sudden large disturbance occurs. However, there is a time operation's limitation of the protection system to eliminate disturbance before the system becomes unstable and loses its synchronization. Critical Clearing Time (CCT) is the toleration time to eliminate the fault to keep the system stable. To improve system stability, installing Supercapacitor Energy Storage (SCES) can be one of the methods for extending the CCT values. SCES absorb large amounts of electricity simultaneously when a fault occurs. This paper proposed a determination of SCES' controller effect in extending the CCT. SCES becomes a dummy load and extends the CCT value depending on the controller's ability to respond to a fault. Controller modeling is applied to SCES, which is installed at the bus generator with determined capacity. The modified Fouad and Anderson 9-bus 3-machine system with a single machine to an infinite bus is used to validate the proposed method. Moreover, the critical trajectory method, which is known as a faster calculation and better accuracy than the time domain simulation method, is used to obtain the CCT value. The result shows that the faster controllers work against fault, the higher the CCT value improvement of system CCT. The highest improvement occurs when the controller works at 0.001s.

Abstract

The system can maintain its synchronization under a transient condition. The transient stability system can be evaluated using the critical trajectory method by calculating the Critical Clearing Time (CCT). The advantage of using a critical trajectory method is that the CCT can be found directly and more accurate than the time domain simulation method. This paper proposed the addition of Supercapacitor Energy Storage (SCES) and damping to enhance the transient stability on multi machine system. SCES is an electrical energy storage device that quickly stores and supplies large amounts of electricity, while damper winding damp the oscillations during unstable steady state conditions. Within the addition of SCES and damping in the system, the stability will last longer than before. The stability system is seen by the extended CCT. Furthermore, multi-machine to infinite bus used to validate the proposed method. The test system also includes the Automatic Voltage Regulator (AVR) and the governor
