1. Abstract We consider an optimal control problem of optimal hydrothermal scheduling. The model, already discussed in [1], is deterministic and takes into account the dependence of efficiency of hydroelectric energy with respect to the volume of water in dams. The thermal cost is a strongly convex and nondecreasing function of the thermal power. We study the possible occurrence of a singular a...

This paper presents a metaheuristic approach based on the Honey Bee Mating Algorithm (HBMA) to the problem of hydropower reservoir optimization. As shortage in power resources becomes more and more pressing, the issue of obtaining more power using less primary energy resources, in general, and less water resources, in particular, becomes an important target for the efficient usage of hydropower...

We describe some features of a three-dimensional numerical simulator currently under development for studying water physico-chemical properties during the flooding of hydroelectric plants reservoirs. The work is sponsored by the Brazilian Electric Energy National Agency (ANEEL) and conducted with Furnas Centrais Elétricas S. A., the leading Brazilian power utility company. An overview of the si...

Much electrical generation in the developed world is now conducted within deregulated energy markets, providing new layers of uncertainty for human controllers and new challenges for analysts wishing to understand and support cognitive work. In this paper we outline some of the challenges encountered when attempting to describe the work domain of hydroelectric power generation in a dynamic dere...

The solar-hydroelectric (SHE) energy system is a renewable hybrid consisting of solar and hydroelectric energy. An optimization algorithm has been designed to work out the installed power size SHE system, which planned be integrated into existing systems. This provides optimum with benefit/cost approach. value hydro cost also generation taken from actual values since it's an facility, electrici...

Hydroelectric energy is a major source of renewable electricity in the world. The industry is continuously searching for ways to improve the efficiency and reliability with which it produces energy. The turbine governor plays vital role in keeping frequency constant. Here we proposed a fuzzy approach to turbine governor by utilizing human experience. The simulation model of Hydro Power Plant (H...

Environmental pollution and rapid depletion are among the chief concerns about fossil fuels such as oil, gas, and coal. Renewable energy sources do not suffer from such limitations and are considered the best choice to replace fossil fuels. The present study develops a mathematical model for optimal allocation of regional renewable energy to meet a country-wide demand and its other essential as...

Transient events often account for most of the fatigue damage sustained by hydroelectric turbines during operation. Since one of these damageable events is load rejection, this paper presents a study of the dynamic response of two hydroelectric turbines during load rejection. The two turbines are similar in design and in overall measured behavior. However, we observed that the two turbine runne...

The use of Ti 3 C 2 T x MXenes/polyaniline composite tremendously improved the electrokinetic energy conversion efficiencies nano-hydroelectric generators, demonstrating a power output sufficient to charge commercial battery for very first time.
