World Hydropower Capacity Evaluation

摘要: A continuous population growth and increasing energy demand combined with depleting traditional reserves puts a pressure on conventional methods of electricity generation. The desire ambition to create more sustainable society paves the way for ‘renewables’. Hydropower or Hydroelectricity already plays significant role in global production, especially large hydropower plants giant reservoir lakes. contribution small micro however is not really clear. Smaller have some advantages compared larger terms sustainability, local benefits supply remote areas. exact location potential mostly unknown total all capacities certain region has been evaluated as well. This research aims give insight specific distinguishes micro, hydropower. In order evaluate systematical method developed simulate input data check whether there at location. approach based distributed model raster data. world divided into cells 3” (three seconds 92m near equator) resolution. For each every cell capacity systematically determined. do this two basic components hydropower, head discharge need be cell. calculated help HydroSHEDS’ DEM DIR datasets GRDC Runoff fields’ dataset. Based Flow Direction, derived by HydroSHEDS ‘runoff weighted’ flow accumulation was executed obtain accumulated runoff which converted discharge. size slope within from modified map RiverDEM forms basis calculation. using Input Variables ‘turbine efficiency’, ‘minimum discharge’ head’. results are filtered locations. To per category 0,50 degree times (about 50 km2). final output resolution degree. It computed that gross theoretical about 20TW Asia largest contributor. Large accounts over 80% while only 2% capacity. paper demonstrates new, insightful images spatial distribution, showing Colombia, Myanmar, Indonesia Madagascar examples areas extensive potential. Overall study provides consistent modeling allows both quick comparison between regions detailed information
