We conduct a benefit-cost analysis of a relicensing agreement for two hydroelectric dams in Michigan. The agreement changed daily conditions from peaking to run-of-river flows. We consider three categories of costs and benefits: producer costs of adapting electricity production to the new time profile of hydroelectric output; benefits of reductions in air pollution and greenhouse gas emissions;...

Electricity production from renewable energy sources (RES) is being promoted worldwide as a way to decrease CO2 and pollutant emissions. Nowadays special regime generation in Spain corresponds to cogeneration, renewable and biomass (photovoltaic solar power, wind power, geothermal, small hydro plants, and biomass and waste power plants) and urban and mining waste. Some of these RES are highly i...

In this paper, a neural Pseudoderivative control (PDF) is applied to a nonlinear mathematical model of the Dinorwig pumped storage hydroelectric power station. The response of the system with this auto-tuning controller is compared with that of a classic controller, currently implemented on the system. The results show how the application of PDF control to a hydroelectric pumped-storage station...

nowadays,it is important to consider environmental issues,as ecological problems and their severe effect intensify in iran,particularly in khuzestan province.the environmental effects of hydroelectric plants are highly regarded due to their significant impact on an extensive area.the lack of safe path for fish passing through the turbines is one of these damages. in order to deal with these cha...
