Abstract:

The article describes run-of-the-river hydroelectric power plants. The authors specify the importance of performing technical and economic calculations in justifying the large-sized units of the water-supplying channel of a run-of-the-river hydroelectric power plant: turbine pits and suction (discharge) pipes. The study shows that the amount of construction work and the total cost of building a hydroelectric power plant depend on the size of these water supply units. The research objective is to analyze the validity of establishing the main dimensions of the suction pipes for modern technical

Abstract:

Energy is increasingly becoming more important in today’s world, whereas energy sources are drastically decreasing. One of the most valuable energy sources is hydro energy. Because of limited energy sources and excessive energy usage, cost of energy is rising. Among the electricity generation units, hydroelectric power plants are very important, since they are renewable energy sources and they have no fuel cost. To decide whether a hydroelectric power plant investment is feasible or not, project cost and amount of electricity generation of the investment should be precisely estimated. In this

Abstract:

Major parameters affecting the generation capacity of hydroelectric plants are resource regime, reservoir geometry, and water head together with flow rate and efficiency. For the same resource regime and flow rate, water head can be altered depending on generation planning. By means of holding water in the reservoir and consequent increase in head can lead to boost power generation. In this paper, a method to compare two different operational styles has been identified; a plant operating with a low fixed head has been compared to a plant with an increased water head by means of holding water.

Electricity is an integral part of modern life. The main sources of power generation continue to be the fossil fuels which are largely responsible for global warming. In view of environmental concerns, there is increasing awareness on judicious use of natural resources, including water. Large hydroelectric power plants are generally multi-purpose projects and require huge quantities of water for their operation. Usually the generating units in a hydroelectricpower plant are put in operation to meet the electrical load demand without considering the efficiency of the units, which can lead to ex

Improvements in existing hydroelectric power plants can increase quantity of production, but very often they are also designed to improve its quality, that is, peak generation capacity and availability of reserve energy, which in turn leads to a reduction of emissions in the producer part. An adequate valuation and economic recognition of the energy quality in remuneration seems essential to encourage these improvements. Frequent size discrimination acts against this recognition, because quality of energy is more often present in conventional-sized installations.

Abstract:

The development of hydroelectric power plant is one of the efforts in utilising water resources for people’s welfare by generating the energy for electricity purpose. Nowadays, the installed capacity of hydro electric power plants is 3,529 MW from the total installed capacity 24,846 MW from various power plants owned by PT PLN (Persero) and the hydropower potential 75,000 MW all over Indonesia. Hydroelectric power plant has complex structures and involves large amounts of capital with a long-running construction period. This situation imposes uncertainty factors with considerably high risks. T

Marginal erosions in reservoirs of hydroelectric plants have caused economic and environmental problems concerning hydroelectric power generation, reduction of productive areas and devaluing land parcels. The real extension and dynamics of these erosion processes are not well known for Brazilian reservoirs. To objectively assess these problems Unesp (Univ Estadual Paulista) and Duke Energy are developing a joint project which aims at the monitoring the progression of some erosive processes and understanding the causes and the dynamics of this phenomenon.

Abstract:

The increasing penetration of non-programmable renewable energy sources (RES) is enforcing the need for accurate power production forecasts. In the category of hydroelectric plants, Run of the River (RoR) plants belong to the class of non-programmable RES. Data-driven models are nowadays the most widely adopted methodologies in hydropower forecast. Among all, the Artificial Neural Network (ANN) proved to be highly successful in production forecast. Widely adopted and equally important for hydropower generation forecast is the HYdrological Predictions for the Environment (HYPE), a semi-distribu

The paper dwells upon the problem of multi-criteria choice of ways to develop generating capacities to supply power to remote consumers. We herein propose a two-step multi-criteria analysis method: choosing promising power-generation technology first, and then specifying the generating-capacity structure. The paper describes the structure of the proposed multi-criteria methods: the interval TOPSIS method for Step 1; for Step 2, an upgraded analytic hierarchy process based on identifying the structure of the decision maker’s preferences. We demonstrate the use of this method with evidence from

Renewable energy is one of the most important factors for developed and sustainable societies. However, its utilization in electrical power grid systems can be very challenging regarding rates predictably. Renewable energy depends mainly on environmental conditions such as rainfall-runoff ratios and temperature. Because of that, the expected power production heavily fluctuates, which makes the prediction and calculation of feed-in into the power grid very challenging. The accurate forecasting of energy production is a very crucial issue for power management process. This paper presents the res
