Recent warm, dry summers showed the vulnerability of the European power sector to low water availability and high river temperatures. Climate change is likely to impact electricity supply, in terms of both water availability for hydropower generation and cooling water usage for thermoelectric power production. Here, we show the impacts of climate change and changes in water availability and wat...

The human demand for electricity and fresh water is ever increasing. Due to the nature of hydropower and its economic, social, and environmental benefits, hydropower will be an important contributor to the energy mix of the future. Isolated areas, severely underdeveloped regions, disaster-stricken zones, and remote military outposts have one common need: readily available and efficient means of...

Most of the industrial processes are multivariable in nature. Designing controller for the Multi Input Multi Output (MIMO) process is difficult because of the changes in process dynamics and interaction between process variables. The objective of the current study presented in this paper is to design a multivariable Linear Quadratic Gaussian (LQG) Controller for a sample controlled hydropower s...

In the framework of new feed-in-tariff system in Switzerland for Small Hydropower Plants (SHP), aim SmallFLEX project, led by HES-SO Valais and performed 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 small hydropower plant Gletsch-Oberwald (KWGO) owned FMV...

-Stratified Genetic algorithm was used in the optimized calculation of Wanjiazhai Hydropower Station, a multi-objective optimized model was established , two subpopulations of independent parallel were used to compute, the calculated values of network model and test values were compared, results showed that the two values are matched, the value of optimized load pressure fluctuation deviates fr...

We present an \asset/liability" model for a hydropower producer operating in a deregulated electricity market. The focus in this modeling eeort is on the coordination of physical generation resources in the form of multiple hydropower reservoirs, with \paper" resources in the form of nancial instruments on electricity. These portfolio management instruments are available in functioning forward ...

Aiming at the problem that traditional optimal operation of hydropower reservoir pays little attention to ecology, an optimal operation model of multi-objective hydropower reservoir with ecology consideration is established which combines the ecology and power generation. The model takes the maximum annual power generation benefit, the maximum output of the minimal output stage in the year and ...
