The Cameroon rural western highlands, like most of the developing countries, undergoes a lack electrical energy supply to make easier lightning and tiny industries. During last decades, future technologies renewable energies (Micro-hydroelectric power plant, photovoltaic panels, micro wind tribune) is remarkable in region. From this report, study aims at analysing installed capacities those eme...

Renewable energy facilities will constitute a major contribution to electrical power in the future. The wind turbine will, together with biomass, form the major renewables parts up to year 2030 including erection of offshore wind farms. The wind is a non-storable energy source, whose electric energy needs priming into interchangeable energy to be competitive for large-scale power generation. An...

The promotion of renewable energy sources (RESs) is a key European and national policy aimed at strengthening clean production, decoupling from fossil fuels, responding to climate change commitments. Spatial planning crucial as it can spatially direct the demand for investments in RESs, taking into account challenges related more efficient coexistence RESs environmental assets, both natural man...

In this study, medium capacity hydroelectric power plant (HPP) class was investigated and Yumrutepe HPP case studied in class. For purpose, the effects of parameters, such as energy generation realized plant, monthly average partial pressure, temperature, relative humidity, rainfall mass flow rate water passing through turbines, on efficiency factor Hydroelectric calculated between 2018-2019 ye...

Approximately half of the world's population lives in the tropics, and future changes in the hydrological cycle will impact not just the freshwater supplies but also energy production in areas dependent upon hydroelectric power. It is vital that we understand the mechanisms/processes that affect tropical precipitation and the eventual surface hydrological response to better assess projected fut...

We analyze the price-formation process in an infinite-horizon oligopoly model where hydroelectric generators engage in dynamic Bertrand competition. We provide a simple characterization of a Markov Perfect Equilibrium (MPE) in terms of “indifference” prices — i.e. prices that equate the gains from releasing or withholding water. Although the MPE solution represents an equilibrium consistent wit...

Wind turbines generate electricity without directly emitting air pollutants that are known to affect the climate and human health. Wind turbines, however, do not operate in a vacuum. They are integrated into the larger electrical grid that includes coal and nuclear plants, natural gas turbines, hydroelectric dams, solar panels and other technologies. The interactions between these electricity s...

We consider the valuation of energy storage facilities within the framework of stochastic control. Our two main examples are natural gas dome storage and hydroelectric pumped storage. Focusing on the timing flexibility aspect of the problem we construct an optimal switching model with inventory. Thus, the manager has a constrained compound American option on the inter-temporal spread of the com...

Power production in Korea can be classified into nuclear, thermal, and hydropower generation. The nuclear power plant occupies the largest portion of power generation, whilst hydropower only accounts for 2%. Nevertheless, many people are interested in hydropower generation, because its power generation time is shorter than that of nuclear and thermal power. In addition, it is considered as clea...
