“…The topographic analysis using a DEM, which covers the whole landscape, has identified more than half of the total potential sites outside the two major watersheds in the study area. These potential sites dispersed across the study area present an opportunity for remote areas to harvest hydropower, take advantage of the available resource, and provide power to small communities and small-agro industries, as documented in several studies [53,55]. The study results provide a new perspective on assessing a landscape for potential small-scale hydropower sites to encompass all watersheds irrespective of scale.…”

“…But for the Italian case where large-scale systems were already developed and suitable sites were already utilized, it was emphasized that increasing hydropower contribution could come from small-scale systems [56]. Moreover, many of the small-scale hydropower systems benefit rural development [8,53,55]. The advantages of these systems to rural areas in developing countries include improvement in productivity, women empowerment through energizing small agro-industries, and the notable little environmental impact.…”

“…The advantages of these systems to rural areas in developing countries include improvement in productivity, women empowerment through energizing small agro-industries, and the notable little environmental impact. On a side note, small-scale hydropower systems are also challenged with high initial costs [55], but such can be counteracted by little operation and maintenance costs.…”

Hydropower depends on the elevation head and water flow of a river. However, other factors must be considered, such as the risk associated with surface processes and environmental factors. The study aims to analyze a landscape’s dynamics and locate potential sites for small-scale hydropower systems (<10 MW) using a geographic information system, the curve number method, and the TopoToolbox with a digital elevation model and available spatial datasets. Across Bohol Island in the central Philippines, the study found 94 potential sites with hydraulic heads ranging from 20–62.4 m, river discharges between 0.02 to 9.71 m3/s, and a total hydropower capacity of 13.595 MW. The river profile analysis classified the sites to five levels of risk to geo-hazards, with three-fourths of the sites being at ‘high’ to ‘very high’ risk levels while more than 50% of the total power can be generated in ‘low’ risk areas. Land-use and population constraints reduced the sites to 25 and the hydropower capacity by 60%. Although limited to the table assessment phase of hydropower development, the study showed the potential of small-scale hydropower systems in the study area, their spatial distribution, and the risk associated with each site. The study results provided data-limited resource managers’ and energy planners’ insights in targeting potential locations and minimizing field investigation costs and time.

“…Many locations in Nigeria have many untapped small hydropower (SHP) potential sites. There are currently more than 278 potential SHP sites with 734.3 MW potential capacity but only 37.0MW has been explored to date [13]. This makes mini-scale hydropower backed-up (HPBU) hybrid renewable energy system (HRES) one of the potential sources of electricity generation to increase energy access.…”

This paper reports on a hydro backed-up (HPBU) hybrid renewable energy system (HRES) for a rural off-grid community in Kwara State Nigeria with an average demand load of 550.9 kWh (90.7 kW peak) per day. By using HOMER Pro software, the formulation and identification of the best reliable system architecture for attaining technical and economic viability while using nearby existing RE sources such as hydro, wind and solar energy are appropriately modelled and optimized based on the minimal net present cost (NPC) and cost of energy (COE). It was determined that the three best feasible configurations of a HPBU-HRES for the site have an annual output ranging from 1,642,979 -1,749,272 kWh/yr and a cost of electricity (COE) in the range of 0.34 -0.64 $/kWh. The best optimal HPBU-HRES (system 1) is a combination of 184 kW of solar PV (PV), 4,545 kWh of battery capacity (BB), 81.3 kW of converter (Conv) and 277 kW of hydro generation capacity (HPP). A comparison study undertaken to illustrate the economic benefits of the studied systems shows that about 288,116, 88,342 and 53, 88 kg/yr of CO 2 savings is possible against diesel only, grid extension and first best equivalent diesel engine backed-up (DEBU) system respectively. In furtherance of the study, a sensitivity analysis of the likely variation associated with the metrological parameters, load and cost of components was undertaken. The Outcomes show that system 1 (PV/HPP-BB) is the optimal system for small to medium loads (≤600 kWh/day), irrespective of the solar radiation.

“…Facing the new changes in the global energy pattern, vigorously developing clean low-carbon energy is the main direction of energy development. From a global perspective, as a clean renewable energy source, small hydropower (a single hydropower station with an installed capacity of less than 50,000 kW) resources is almost the main force of hydropower resources and it is the most important support and guarantee to achieve the goal of "carbon emissions peak and carbon neutrality" and realize the energy transformation of human society [1,2]. There has been a great deal of research and many excellent methods proposed in the field of streamflow prediction, for example Costa Silva, D. F. et al [3] proposed an integrated Long Short-Term Memory (LSTM) model that tested streamflow prediction for five scenarios using runoff and rainfall data.…”

The availability of hydrological data for small hydropower plants is an important prerequisite for reservoir scheduling, reservoir flood control and integrated water resources. To address the problem of a lack of hydrological data in small hydropower plants, this paper proposes a method to predict the power generation flow of small hydropower stations without hydrological data using the Soil and Water Assessment Tool model (SWAT) when the traditional data-driven methods cannot study the problem of power generation flow prediction in small hydropower stations well. The method can use gridded meteorological data as the input of the model to solve the problem of small hydropower stations without meteorological data. The problem that small hydropower plants without hydrological data cannot calibrate the hydrological model is solved by calculating the generation flow through the output of small hydropower station and by using the similarity analysis method to migrate the generation flow of similar small hydropower stations. The model was tested in a watershed in southwest China to demonstrate the effectiveness of the proposed method. The results show that the coefficient of determination between the predicted and measured values of small hydropower stations without information is about 0.84, which achieves a better prediction.
