World electricity production today is heavily dependent on water resources. Studies have shown that global warming and climate changes will have significant impacts on available water resources to produce hydroelectric power. Considering that the reservoir dam in the catchment area of Dez is simultaneously a producer of hydropower and supplier of water needed for agricultural land, the aim of t...

-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...

hydropower plant and especially micro-hydropower plant is an available, reliable and economical energy source. micro-hydropower plant is one of the most environment-friendly technology, use and development of which leads to reduction of energy consumption sporadically and worldwide. along with the growth of these power plants, the issues related to the control of electrical parameters such as l...

We present a cost-benefit framework to analyze the interaction between hydropower and salmon in a dynamic context. The framework is used to derive cost-benefit rules for projects that affect wild salmon survival. Our approach is illustrated with data from an ongoing project regarding a potential salmon passage-hydropower conflict in the northern Swedish river Umeälven and its largest salmon pro...

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 ...

In this article we wish to evaluate efficiency of use of Dnieper cascade hydropower plants on the basis of common approaches to environmental management. We evaluate the efficiency of use the flooded areas of the hydropower station in agriculture. Assessment of the man-made risks includes evaluation of static (regular maintenance of dams) and stochastic (probability of artificial tsunami) compo...

This paper proposes a bi-level stochastic optimization problem (a Stackelberg game) to generate optimal bids for a profit maximizing hydropower producer and presents a mathematical approach to solve it. The first level represents the strategically acting hydropower producer also called a Stackelberg leader, while the second level represents the transmission system operator (TSO) also called a S...

A modularization method has been proposed here for the full scope real-time simulation of a large-scale hydropower plant. In this method, the full scope dynamic simulation model can be decomposed into several subsystems that can be calculated independently in every time step, and each kind of subsystem model is developed to be a standard module. Using object-oriented modeling method for the sim...
