Increasing the proportion of renewable capacity in the national energy mix may give rise to a range of economic costs. This paper considers the nature of water use in hydroelectric generation in Scotland. Hydroelectric generation is currently the highest volumetric use of water in Scotland. After calculating this volume, the paper considers the nature of some of the non-priced costs associated ...

Hydroelectric power plants are environmental-friendly as they renewable energy sources and make great contributions to the economies. In addition, in state of insurance electricity network, since can respond demands network a very short time. this study, effect speed governors dispense valve has been added classical control mechanism order accurately predict reaction hydroelectric load requirem...

Hydro-electric development has received increasing attention due to its characteristics of ecological and environmental protection. In addition, aquatic functional zoning plays a key role in the management basin because background basic unit. However, hydropower function seldom been considered zoning. This research proposes framework for on aquatic-and-terrestrial-coupled ecosystem with crowdso...

Developing Canadian hydroelectric resources is a key component of North American plans for meeting future energy demands. Microbial production of the bioaccumulative neurotoxin methylmercury (MeHg) is stimulated in newly flooded soils by degradation of labile organic carbon and associated changes in geochemical conditions. We find all 22 Canadian hydroelectric facilities being considered for ne...

The global energy shortage has revived the interest in hydroelectric power, but extreme geological condition always pose challenges to the construction of hydroelectric power stations with large underground caverns. To solve the problem of safe design of large underground caverns, a Chinese-style intelligent stability design, representing recent developments in Chinese techniques for the constr...

The main feature of a run-off river hydroelectric system is a small size intake pond that overspills when river flow is more than turbines’ intake. As river flow fluctuates, a large proportion of the potential energy is wasted due to the spillages which can occur when turbines are operated manually. Manual operation is often adopted due to unreliability of water level-based controllers at many ...
