The current supply for electricity generation mostly relies on fossil fuels, which are finite and pose a great threat to the environment. Therefore, energy models that involve clean and renewable energy sources are necessary to ease the concerns about the electricity generation needed to meet the projected demand. Here, we mathematically model a hybrid energy generation and allocation system wh...

Information hidden in the characteristics and relationship data of a cascade hydropower stations can be extracted by data-mining approaches to be operation rules and optimization support information. In this paper, with Three-gorge and Gezhouba cascade hydropower stations as an example, two operation rules are proposed due to different operation efficiency of water turbines and tight water volu...

1 Recent droughts and heatwaves showed the vulnerability of the electricity sector to surface water 2 constraints with reduced potentials for thermoelectric power and hydropower generation in different 3 regions. Here we use a global hydrological-electricity modelling framework to quantify the impacts of 4 recent drought and warm years on hydropower and thermoelectric power usable capacity worl...

Regulated rivers in the United States are required to support human water uses while preserving aquatic ecosystems. However, the effectiveness of hydropower license requirements nationwide has not been demonstrated. One requirement that has become more common is "run-of-river" (ROR) operation, which restores a natural flow regime. It is widely believed that ROR requirements (1) are mandated to ...

This paper uses neuro-fuzzy programming to perform a comparison between the different electricity power generation options for Jordan. Different systems are considered: in addition to fossil fuel power plants, nuclear, solar, wind, and hydropower systems are evaluated. Based on cost-to-benefit ratios, results show that solar, wind, and hydropower are considered to be the best systems for electr...

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 ...

Some engineering optimization problems, such as multi-objective daily generation scheduling for the hydropower stations, the objective functions has obvious hierarchy and priority, simultaneously, the constraints is very complex. It is difficult to solve the operation problems by adopting traditional optimal technique. In this paper, a new particle swarm optimization algorithm solving hierarchy...

Renewable energy provides twenty percent of electricity generation worldwide. Hydroelectric power is the cheapest way to generate electricity today. It is a renewable source of energy and provides almost one-fifth of electricity in the world. Also, it generates electricity using a renewable natural resource and accounting for six percent of worldwide energy supply or about fifteen percent of th...

this paper presents a simplifiedlagrangian multiplier based algorithm to solve the fixed head hydrothermalscheduling problem. in fixed head hydrothermal scheduling problem, waterdischarge rate is modeled as quadratic function of hydropower generation andfuel cost is modeled as quadratic function of thermal power generation. thepower output of each hydro unit varies with the rate of water discha...

With world electricity demand increasing, exploitation of the considerable potential for hydropower generation in many developing countries is an attractive prospect. However, with increased awareness of the potential adverse effects of hydropower and the underlying need for cost-effectiveness, decisions on the scale of new developments are more difficult to make. This paper compares large, sma...
