Abstract

The rooftop of the University of Medan Construction building which has an area of 210 m2 can be used as a solar power plant (PLTS). Installing PLTS in buildings has several advantages, namely as a long-term energy investment and easy to integrate with the grid electrical system. PLTS is designed to save electricity consumption. In addition, if PLTS is connected to a battery, it can meet some of the energy needs at night. To design a PLTS installation in the Integrated Laboratory building, this research uses technical and economic analysis methods. Technical analysis is carried out to determine the capacity and number of PV mini-grid components required for installation. While the economic analysis aims to calculate the investment costs and the length of time for the return on investment compared to buildings without PV mini-grid installations. Based on this research, the results show that the amount of energy required for the Integrated Laboratory building is 482.148 kWh, while the planned PLTS is able to provide energy of 216,128 kWh. The PLTS design requires an initial investment of Rp. 927,700,894,-. So by using the Payback Period (PP) method, it can be concluded that the planned design is feasible, because the comparison of the cost of return on investment is 9.13 years faster than the project age that has been determined previously, which is 20 years.

Abstract

Penelitian ini membahas secara komprehensif perancangan sistem manajemen termal (thermal management system) pada energy strorage system (ESS) berbasis baterai lithium-ion yang diaplikasikan pada Stasiun Pengisian Kendaraan Listrik Umum (SPKLU). Sistem ini dirancang untuk menjaga suhu operasional baterai tetap dalam kisaran yang aman melalui pendekatan pendinginan pasif menggunakan Phase Change Material (PCM) serta pelat pendingin berbahan aluminium. Metode penelitian dilakukan secara eksperimental melalui simulasi numerik menggunakan perangkat lunak SolidWorks, dengan dua skenario utama yaitu simulasi kondisi pengisian cepat (fast charging) dan simulasi pelepasan energi. Hasil simulasi menunjukkan bahwa sistem mampu menjaga suhu BMS tidak melebihi 58°C, sementara suhu pelat pendingin utama dapat mencapai serendah 43°C pada saat pelepasan energi. Sistem pendingin yang dikembangkan menunjukkan kinerja yang optimal dalam menyebarkan panas secara merata, menjaga kestabilan suhu kerja baterai, dan meningkatkan efisiensi serta keselamatan operasional dari ESS pada SPKLU. Dengan demikian, desain sistem ini dapat menjadi solusi inovatif untuk mendukung keberlanjutan teknologi kendaraan listrik di masa mendatang.
