Abstract

The use of photovoltaic panels (PV) as the latest material technology to conversion solar energyinto electrical energy, so as it can become a Solar Power Plant (PLTS) which is more continues to growin this world, including Institut Teknologi Sumatera (ITERA). As a new campus technology-based inLampung Province which also has high solar potential, it is considered appropriate to be able to applyphotovoltaic as the key to the use of renewable energy. The PV panel studied is a comparison with theplacement conditions, specifically placement on the rooftop and on the groundmounting. In order to getthe best efficiency from the comparison of the installed photovoltaic panels, it is necessary to design anequivalent circuit with a load or no load in designing, as well as making observations for 7 days withthe same conditions. The results show that the placement of PV on the rooftop is 1,129.91 Wh for aloaded condition and 3,961.91 Wh for a no-load condition, while the placement of PV on thegroundmounting is 1,064.83 Wh for a loaded condition and 3,880.13 for a no-load condition. Fromthese results, it becomes the basis for the placement of PV as needed before planning the constructionof PLTS.

Abstract

PLTS 1 MWp on-grid at the Sumatra Institute of Technology (ITERA) campus comprises solar modules, inverters, DC cables, and protection equipments assembled in a compact system. Each of these components has a role in transmitting the electrical energy generated by the solar module to the electrical load at ITERA. This paper will discuss the power losses generated by PLTS components, especially the DC distribution cables used. The simulation of PVSystV6.81 obtained 1.98% of the losses resulting from the distribution process on the DC cable. The simulation results were compared with the measurement results from the solar fusion software, which records the power components generated by PLTS ITERA such as voltage, current, power, etc. for each string connected to the inverter with a data collection duration of 5 minutes (12 hours per day 06.00 – 18.00). Based on data obtained from fusion solar in August and formula calculation, the lowest average percentage loss of energy from DC cables is 0.6542% on inverter 6, and the highest is 0.6718% on inverter 1. The difference losses of each inverter are caused by disturbances in the DC cable distribution line from the module to each inverter, such as short circuit current to ground.

Abstract

Pemasangan Distributed Generation (DG) memiliki manfaat diantaranya untuk mengurangi rugi-rugi daya, memperbaiki nilai tegangan dan meningkatkan kualitas daya pada sistem distribusi. Lokasi penempatan DG dan kapasitas DG yang tidak optimal pada sistem dapat meningkatkan rugi-rugi daya yang dapat mempengaruhi turunnya profil tegangan. Penelitian ini mengusulkan algoritma optimasi Flower Pollination Algorithm (FPA) untuk menentukan penempatan lokasi untuk mengurangi rugi-rugi daya dan menentukan kapasitas DG yang optimal pada studi kasus jaringan distribusi Semanu, Yogyakarta. Penelitian yang dibagi menjadi dua skenario dimana pada skenario pemasangan satu/single DG didapat lokasi yang optimal terletak di Bus 32, dengan kapasitas 8307,47 kW dan rugi-rugi daya menurun 70,41%. Pada skenario pemasangan dua/multi-DG lokasi yang optimal terletak di Bus 17 dan 37 masing-masing berkapasitas 4479,46 kW dan 5294,91 kW, dan rugi-rugi daya menurun 81,22%. Pemasangan multi-DG lebih andal dibandingkan dengan satu/single DG karena memiliki rugi-rugi daya yang lebih minimum.
