Abstract

One the problem of electric power stability is due to load fluctuations in distribution system especialy during peak load conditions. One solution which is applied in Smart Grid scheme is through load shifting or power shifting. In load shifting the load with high power consumption which operates at peak load shifted its operations outside of the peak load or s some loads with high power consumption do not operate at the same time, there is a load whose operating time is shifted to reduce peak power. Power shifting is used when energy from renewable source not directly suplied to load but storage first and supplied to reduce high power consumption to reduce peak power. Low load factor, ratio between average power to peak power, may affect to power system operation. If load factor of residential load can keep in low, it will be certainly help improve the stability of the power system. In this study we will examine the comparison of load shifting method with power shifting in improving load factor. Load shifting is done to water pumps and washing machines, because washing machine is shiftable load. Power shifting is made to the output power of the solar power plant, which is used to reduce peak power from the water pump. Test results show that power shifting can increase load factor value up to 54,9% while load shifting give load factor value equal to 43,9%.

Abstract

One of the main challenges in building a Solar Power Generation System at home or a Home Solar Power Plant (Home SPP) is choosing component specifications according to price. The main components of Home SPP are photovoltaics (PV) panels, inverters, and wiring systems. Given the strict price constraints, the selection of parts available on the commercial market is generally of low quality. However, low-quality components can still provide a significant advantage by optimizing the plant design. This research proves that the proper configuration can reduce electricity bills by 52.2%. This configuration does by choosing a Grid Tie Inverter (GTI) with a high working voltage and a 12 Volt PV configured in a parallel series circuit to work at 24 Volts. In addition, the 12 Volt PV panels configured in series to 24 Volts are proven to increase the conversion efficiency.

Abstract

Solid oxide fuel cell (SOFC) power plants offer a promising pathway toward highly efficient energy conversion compared to conventional systems. This study explores the impact of output temperature variations on system performance through simulation analysis. The results demonstrate that increasing the temperature difference between the fixed input (700 °C) and the cell output significantly enhances net efficiency, while gross efficiency remains relatively stable. At an output temperature of 875 °C, the system achieves a net efficiency approaching 50% and a gross efficiency of approximately 61%. These findings emphasize the critical role of output temperature in determining overall system efficiency and highlight the importance of thermal management in SOFC operation.

Abstract

Desa Ciwaruga salah satu di antara beberapa desa di Kabupaten Bandung Baratyang mengikuti program Pemberdayaan Desa Binaan di Politeknik Negeri Bandung.Mempunyai permasalahan penerangan jalan umum yang kurang. Apabila malamtiba, beberapa lokasi yang jauh dari rumah warga dalam keadaan gelap. Hal inimenyebabkan rawan kecelakaan dan kriminal. Sebenarnya, pemerintah desa danmasyarakat desa telah memasang PJU di beberapa lokasi. Namun tidak ada anggaranuntuk perawatan dan pembayaran tagihan listrik dari PT PLN, sehingga PJU tersebutkembali tidak berfungsi. Solusi yang ditawarkan adalah program kerja sama PKMantara Jurusan Teknik Konversi Energi (JTKE) Politeknik Negeri Bandung (Polban)dengan Desa Ciwaruga, utamanya adalah menumbuhkembangkan kesadaranmenggunakan EBT (Energi Baru Terbarukan) secara berkelanjutan dan menciptakanDesa Mandiri Energi. Hal ini diawali dengan pemanfaatan energi surya untuk menerangiarea tertentu (Jalan Umum) dengan menggunakan PLTS. Sehingga secaraumum langkah yang diambil agar program dapat berlangsung secara efektif mencakuptahapan: pengenalan teknologi PLTS, penjelasan instalasi PLTS untuk PJUES,pemasangan PJUES, diakhiri penjelasan tentang perawatan dan perbaikan PJUES.Program ini telah menghasilkan terpasangnya unit Purwarupa PJUES di titik strategisyang sebelumnya gelap dan rawan, serta meningkatkan pemahaman masyarakatmengenai teknologi EBT.Warga kini memiliki kemampuan dasar untuk merawat danmemperbaiki PJUES secara mandiri.
