The integration of wind power in power systems results in a reduction in greenhouse gas emissions. Thus, it has a positive environmental impact. However, the operation of these power systems becomes increasingly complex, owing mainly to random behaviour of the wind. In the case of island power systems, this problem is even more difficult. The traditional solution is to use diesel generators as ...

The need for electrical energy in Nehibe village is currently increasing along with the increase population and new households. demand electricity this reaches 18 kW, an average power per household of 450 VA. problem that Hachakwa Micro Hydro Power Plant (PLTMH), which very close to village, has a capacity only 10 kW. Based on problem, study aims design peltor turbine two nozzles 26 kW PLTMH. T...

Abstract In the framework of new Swiss feed-in-tariff system for Small Hydropower Plants (SHP), aim SmallFLEX project, led by HES-SO Valais and performed in collaboration with EPFL, WSL, EAWAG, PVE FMV, is to show how SHP can provide winter peak energy ancillary services, whilst remaining eco-compatible. The pilot demonstrator site selected Gletsch-Oberwald (KWGO) owned FMV commissioned end 201...

Cross-flow turbines have recently been proposed for energy recovery in aqueducts when the outlet pressure is greater than zero, owing to their constructive simplicity and good efficiency within a large range of flow rates head drops. In case high drop (higher 150 m) relatively small discharge (lower 0.2 m3/s), traditional design these leads very widths nozzle runner; as consequence, friction lo...
