“…Saat ini, tingginya emisi gas rumah kaca telah mendorong perubahan parah di atmosfer. Jadi, penting untuk bergerak maju penggunaan sumber daya energi yang berkelanjutan (Hatata, El-Saadawi, and Saad 2019). Desa Batur Kecamatan Gading merupakan salah satu desa yang berada di wilayah Kabupaten Probolinggo yang berada di lereng Gunung Argopuro dengan Luas wilayah sekitar 436.81 ha (Uddin et al 2019) Dampak luaran perbaikan PLTMH diharapkan membantu aktifitas kegiatan masyarakat seperti pertemuan warga, mengaji dan lainnya masih terfokus di siang hari karena di malam hari kondisinya masih gelap dengan daya listrik terbatas.…”

Nowadays, direct media use in learning energy is rarely found. Therefore, the authors intended to design a mini micro-hydro power plant (MHPP) in order to give direct experiences to students. This study generally aims to develop a mini MHPP consisting of equipment design, component selection, and the MHPP assembly. A test on discharge, heights, and produced power is then conducted. The data acquired are then analyzed in terms of either Pteotirik or Preal power using a predetermined equation. An analysis to the factors influencing the P values is then carried out. The power input of resulted from the water discharge management is 35.64 mW, while that of the power output is 9,61 mW. The efficiency of the MHPP set is by 26.96% which is considered quite low due to such factors as turbine blades, penstock pipes, generators, and the shift from water potential energy to other types of energies which is inevitable. It is expected that the developed mini MHPP is applicable as practicum learning media giving a lot of such learning experiences to students as to identify how hydroelectric power plant is, how the water energy shifts into electric energy, how high the electricity produced is, and to analyze factors influencing how high and low the electricity produced by a power plant.

“…Distributed generation (DG), through different renewable resource plants, even of low power, may contribute significantly to the increase in sustainability at the local and global level [5,6]. According to [7], small hydropower plants can be considered one of the best methods for producing renewable energy, as long they are based on cheap, reliable, mature technologies and do not cause significant environmental changes where installed. Small hydro power plants up to 5 kW are classified as pico-hydro systems [8] and have potential in meeting growing energy demand, once they allow widespread exploitation of small rivers, shallow water reservoirs, and wastewater [7,9].…”

Very small-scale hydropower plants are environmentally friendly and renewable resource-based innovative solutions. The interest in pico-hydro systems (up to 5 kW) has increased significantly from the first stand-alone applications, at remote sites, to the distributed generation, with the injection of generated energy into the grid. Recently, there have been advances in the grid connection of these systems using off-the-shelf components, namely photovoltaic inverters. Therefore, pico-hydro systems have gained an enormous potential in distributed generation, particularly in the context of microgrids. However, in situations of over-power, or whenever the generator is under no load, e.g. when the grid fails, there is a need for effective over-voltage protection, as in small wind turbines. This paper proposes two over-voltage protection circuits, designed to ensure the integration of pico-hydro turbines connected to the grid using conventional photovoltaic microinverters and string inverters, for power ranges of 300 W and some kW, respectively. Extensive tests were performed on an emulation platform and a workbench using these two different over-voltage protection circuits. One is designed to connect the generators of water wheels to the grid and the other to connect 1500 W generators of water turbines. The experimental results demonstrated the performance of the proposed over-voltage protection circuits in four different situations. Both avoid irreversible damages of generators, photovoltaic microinverters and string inverters in the context of the above-described grid connection approach.
