Abstract
Sebagai salah satu pusat beban di wilayah Sumatra, sistem kelistrikan Provinsi Sumatra Utara tahun 2022 mengalami pengembangan yang signifikan, yaitu pada transmisi 275 kV sebesar 440 kms dan Gardu Induk dengan total kapasitas 1030 MVA. Adanya perubahan sistem kelistrikan yang signifikan, menjaga stabilitas sistem tenaga menjadi permasalahan utama dari operasi sistem yang kompleks. Dalam kondisi ini, sistem dapat distabilkan dengan peralatan Flexible AC Transmission Systems (FACTS). Salah satu peralatan FACTS yang umum digunakan adalah UPFC (Unified Power Flow Controller). UPFC dapat berfungsi mengatur tegangan dan aliran daya pada bus untuk sistem kelistrikan yang optimal. Indentifikasi kestabilan tegangan menggunakan metode continuation Power Flow (CPF) melalui kurva PV untuk melihat kondisi tegangan profil saat mencapai Maximum Loading Parameter (MLP). Bus dengan profil tegangan dibawah 0,95 pu dan menghasilkan penurunan losses paling besar dipilih sebagai bus kritis untuk lokasi pemasangan UPFC. Tujuan pada tugas akhir ini untuk membandingkan sebelum dan sesudah pemasangan UPFC terhadap stabilitas tegangan di sistem. Dengan pemasangan UPFC pada bus kritis mampu meningkatkan profil tegangan dengan persentase 0,01-2,09%, dan menurunkan losses pada sistem sebesar 3,7MW (6,39%), sehingga daya pembangkitan sistem menjadi turun dan biaya pembangkitan sistem semakin murah.

As one of the load center in Sumatra, North Sumatra provincial electricity system in 2022 occured a significant development, that is 440 kms of transmission 275kV and 1030 MVA of total capacity substation. Changing significant in the electrical system, to maintain the stability of the power system is the main problem of the operating system. In this condition, the system can be stabilized with equipment Flexible AC Transmission Systems (FACTS). One of the FACTS equipment commonly used is UPFC (Unified Power Flow Controller). UPFC can function to regulate the voltage and power flow on the bus for optimal electrical system. Identify of voltage stability using Continuation Power Flow (CPF) through PV curve to see the condition of the voltage profile when reach Maximum Loading Parameter (MLP). Bus with voltage profile below 0,95 pu and gives lowest power losses on the system is selected as critical bus for UPFC installation. The purpose of this final project to compare before and after installation of UPFC on the voltage stability in the system. The installation of UPFC on the critical bus is able to increase the voltage profile with percentage 0,01-2,09%,and to decrease losses in the system with value 3,7MW(6,39%), so that the power of generation become smaller and the cost of generation system is getting cheaper.
