"Pada sistem tenaga listrik yang mengalami pembebanan berat, kestabilan tegangannya akan sulit untuk dipertahankan. Karena tegangan berkorelasi dengan frekuensi, pembebanan berat ini dapat menyebabkan kegagalan sistem. Untuk mempertahankan stabilitas tegangan, cara yang umum adalah dengan menginjeksikan daya reaktif pada bus-bus yang lemah. Kombinasi program Tinier aliran daya dan analisis Eigen dapat digunakan untuk meneliti batas stabilitas tegangan sistem. Nilai Eigen yang kecil dari matrik Jacobian tereduksi menunjukkan bus-bus yang mengalami ketidakstabilan tegangan. Nilai faktor partisipasi yang besar dari bus yang mengalami ketidakstabilan tegangan menunjukan lokasi penempatan kompensator daya reaktif yang terbaik, yang akan memperbaiki stabilitas tegangan sistem."

"Applied supply side Management of electric Energy in Supply side. This is prior in order tooptimalize of using Hydro generation so it could operation as maximal as possible in the peak of systemloading. In this WG] eficiency of using minimum fuel as expected can be occur in Operation theThermal Generation.In order to have an optimum .system, in Electric Power System that consist of unit Hydro Generationand other Thermal Generation such as PLTU1 PLTP, PLTGDI PLTG. A loading regulation is necessaryto build in an electrical power generation, in order to have an optimum operation for electric powersystem, in which minimum fuel cost in operation electric energy need all. It is important to do because theelectrical power generation serves electric power loads, that always change by the time, and also resultfuel-cost per unit time in rupiahs pers hours, changes by the time.The cost of Electrical Power System operation is set as the goal to be minimized and the junction ofoperation cost will be change. Gradient Method will be used in order to solve this hind of matters. Theoptimum of generation regulation in this paper was restricted as generation regulation of real powerwhenever the optimum generation using this gradient Method is more profitable then using merit ordermethod technically and economically.In this case Computer program will be Applied using computer simulation in which Borland Delphirelease 7.0 as computer language programming, in order to to find an optimization of operation systemhydro-thermis power generation. As the result of Computer simulation program, is picture, table or chartthat would be easier to be understood."

"Gangguan dalam menghasilkan sistem tenaga listrik dapat menyebabkan ketidakstabilan tegangan pada sistem beban. Ketidakstabilan tegangan dalam sistem menyebabkan sistem beroperasi secara tidak normal yang menyebabkan keruntuhan tegangan atau pemadaman total di seluruh sistem. Makalah ini membahas analisis stabilitas tegangan statis dan dinamis dari Sistem Tenaga Senayan-Sambas dengan menggunakan perangkat lunak ETAP12.6.0 untuk simulasi aliran beban dan simulasi analisis sementara. Perubahan pengaruh persentase beban dan catu daya reaktif dari tegangan sistem akan diamati menggunakan analisis statis. Skema pelepasan beban dengan relai di bawah tegangan dan kompensator daya reaktif dalam beban, yang akan dilindungi ketika terjadi gangguan masif pada generator, akan digunakan sebagai sistem. Skema pelepasan beban disampaikan untuk mengembalikan dan menstabilkan tegangan sistem. Skema tersebut kemudian akan menjatuhkan beberapa beban prioritas tinggi dari sistem. 15 MVA atau 12,32% dari seluruh beban akan dihemat untuk mencegah beban dari tersandung kompensator daya reaktif yang digunakan dengan 30 capasitive rating MVAR.

Interference in generating electric power systems can cause voltage instability in the load system. Voltage instability in the system causes the system to operate abnormally which causes a voltage collapse or a total blackout throughout the system. This paper discusses the static and dynamic stress stability analysis of the Senayan-Sambas Power System using ETAP12.6.0 software for load flow simulations and transient analysis simulations. Changes in the effect of the percentage load and reactive power supply of the system voltage will be observed using static analysis. A load release scheme with a relay under voltage and a reactive power compensator in the load, which will be protected when there is massive interference with the generator, will be used as a system. The load release scheme is delivered to restore and stabilize the system voltage. The scheme will then drop some high priority loads from the system. 15 MVA or 12.32% of the total load will be saved to prevent the load from tripping over the reactive power compensator used with 30 MVAR rating capacities."

"Kementerian Energi dan Sumber Daya Mineral telah menetapkan tujuan untuk melistriki seluruh pelosok tanah air, termasuk di daerah terpencil. Ansus merupakan salah satu daerah tersebut karena letak geografisnya yang tidak memiliki akses darat. Pemerintah Papua telah memulai proyek pembangunan pembangkit listrik tenaga fotovoltaik off-grid. Tujuan dari tugas akhir ini adalah untuk mengevaluasi efisiensi dan produktivitas sistem tenaga listrik proyek pembangkit listrik Ansus PV saat ini. Mengeksplorasi jurnal tentang PV, pengambilan data dari simulasi HOMER, dan berkonsultasi dengan orang lain termasuk pembimbing skripsi adalah cara-cara dalam menyelesaikan skripsi ini. Melalui bantuan simulasi HOMER, pembangkit listrik Ansus PV akhirnya mampu menyuplai 350 kWp (1.750 panel surya, 600 baterai, dan 160 kW inverter) dengan kemampuan menghasilkan 606 kWh / hari. Sistem tersebut dinilai berlebihan karena memiliki kelebihan energi yang besar yang dapat digunakan untuk menyuplai 410 rumah lagi. Oleh karena itu, ringkasan biaya pembangkit listrik Ansus PV adalah; Cost of Energy (COE) Rp. 5.838, Net Present Cost (NPC) Rp. 17,815 Miliar, dan Biaya Modal Awal Rp 18,38 Miliar.

The Ministry of Energy and Mineral Resources has set a goal to provide electricity to all corners of the country, including in remote areas. Ansus is one such area because of its geographical location which does not have land access. The Papuan government has initiated an off-grid photovoltaic power plant construction project. The purpose of this final project is to evaluate the efficiency and productivity of the current Ansus PV power system power system. Exploring journals about PV, collecting data from HOMER simulations, and consulting with other people including thesis supervisors are ways to complete this thesis. With the help of HOMER simulations, the Ansus PV power plant is finally able to supply 350 kWp (1,750 solar panels, 600 batteries, and 160 kW inverter) with the ability to produce 606 kWh / day. The system is considered redundant because it has a large excess of energy that can be used to supply another 410 houses. Therefore, the summary of the cost of the Ansus PV power plant is; Cost of Energy (COE) Rp. 5,838, Net Present Cost (NPC) Rp. 17.815 billion, and initial capital costs of Rp. 18.38 billion."
