Abstract
The addition of the power source to the main network is one way to improve the quality of electric power system, network reliability and to reduce power losses. The addition of the energy source is a smart microgrid system. The smart microgrid technology is a technology that uses renewable energy as a main supply. Smart microgrid system consists of a 24 kWp solar power, Wind Turbine 5 kWp system 240 kVAh battery and genset 20 kVA. The smart microgrid system to be implemented at the Engineering Faculty of Udayana University. The results showed the power loss (losses) on the electrical grid at FT Bukit Jimbaran before the advent of smart microgrid system to the network, acquired losses of 6.4 kW or 3.68% of the total load when the network is supplied from PLN and after the inclusion of smart microgrid system and generator sets to the grid obtained by losses of 1.2 kW or decreased losses of 0.69% of the total expenses of 173.54163 kW. Reliability indices obtained at the Technical University of Udayana network after the entry smart microgrid system when interconnected with PLN namely SAIFI: 0.1029, SAIDI: 1.9229 hours / customer, and CAIDI: 18.686 hours / interruption.

2015, Perencanaan Sistem Jaringan Mikro (Microgrid) dengan Supply dari Pembangkit Listrik Tenaga Surya (PLTS) dan Generator Set di Jurusan Teknik Elektri Universitas Udayana
Summary
Fakultas Teknik Universitas Udayana terdiri dari 5 jurusan, yakni Jurusan Teknik Sipil, Teknik Elektro, Teknik Mesin, Arsitektur, dan Teknologi Informatika. Di Jurusan Teknik Elektro Universitas Udayana saat ini sedang dipasang Smart microgrid system. Smart microgrid system yang terdiri dari PLTS dengan kapasitas 24 kWp, Wind Turbin 5 kWp yang menggunakan sistem baterai 240 kVAh sebagai media penyimpan energi dan generator set 20 kVA Smart microgrid system akan dipasang gedung DH Jurusan Teknik Elektro dan Komputer (JTEK). Smart microgrid system ini akan menyuplai beban yang ada di gedung DH JTEK yang digunakan sebagai gedung perkuliahan. Gedung-gedung lain ada di Fakultas Teknik, selain Jurusan Teknik Sipil, akan mendapat suplai dari smart microgrid system yang akan diinterkoneksikan dengan genset 60 kVA dan jaringan PLN. Kedua kondisi ini akan dianalisis rugi-rugi daya dan keandalan jaringan. menggunakan Load Flow Analisys dan Reliabillity Accessment
