Abstract:
Abstract The main goal of this study is to forecast total electricity and hydroelectricity energy generation using historical electricity energy production data in order to determine the future level of electricity and hydroelectricity energy generation in Turkey. For this purpose, Turkey's electricity energy sector was reviewed during the period of 1940–2005. The total electricity and hydroelectricity energy generation were then modelled using historical energy generation data as years with regression analysis. Additionally, the portion that hydroelectric energy generation of Turkey has within total electricity energy production and probable meeting capacity of Turkey's hydroelectric potential of its future total demand was determined. According to the results, it is deduced that hydropower energy will have portion of 13.6% within the total electricity energy generation in 2030. In addition, it is concluded that the whole of Turkey's technical and economical hydroelectric energy potential that is equal 129.9 billion kWh will be used in the year of 2102 if the current trend continues.Keywords:

Abstract Pumped hydroelectric storage is currently the only commercially proven large‐scale (>100 MW ) energy storage technology with over 200 plants installed worldwide with a total installed capacity of over 100 GW . The fundamental principle of pumped hydroelectric storage is to store electric energy in the form of hydraulic potential energy. Pumping typically takes place during off‐peak periods, when both electricity demand and electricity prices are low. Generation takes place during peak periods, when electricity system demand is high. Pumping and generating generally follow a daily cycle but weekly or even seasonal cycling is also possible with larger pumped hydroelectric storage plant. Pumped hydroelectric storage is a flexible form of electricity generation and can contribute many benefits to power systems operation. There has been a renewed commercial and technical interest in pumped hydroelectric storage recently with the advent of increased variable renewable energy generation and the development of liberalized electricity markets.

Abstract—Hydroelectric power, one of the most important
sources of mass generation of electric power, is a renewable
source of energy. The amount of electricity that can be
produced by a hydro-electricity generating system depends on
systemic variables viz; plant efficiency, volumetric water flow
through the turbine and the head of the water from the water
surface to the turbine. The availability of the Water in the
reservoir is a function of some hydrological variables principal
among which are rainfall, reservoir inflows and evaporation.
Understanding the dynamics of these variables, and the
correlation between them are core to proper planning and
management of a hydroelectric power station. In this Study,
simple mathematical methods that include linear programming
and statistical analysis based on simulation techniques were
used to evaluate vital parameters based on the hydrologic data
obtained from the Hydrologic Units of the Shiroro Power
Stations in Nigeria. The overall aim of the study is to idealize
power generation at Shiroro dam in and out of rain season so
as to ensure optimum generation of electricity all year round in order
to achieve energy sufficiency in Nigeria.

In recent years, due to the need for economic development and the launch of the double carbon target, a large amount of hydropower has been put into operation, posing a threat to the safety of the power grid and causing abandonment problems in some areas during the flood season. Therefore, fully grasping hydropower generation forecasting technology is an important way to ensure the safe and stable operation of the power grid and reduce the problem of water abandonment. For the existing hydropower generation forecasting technology lacks the analysis of the impact of upstream and downstream neighboring hydropower. A generation forecasting method that considers the coupling effect of adjacent hydropower is proposed. The method considers the hydropower runoff topology relationship and uses the relevant generation data of adjacent hydropower as features to model the generation of the target hydropower. The hydropower generation power is affected by multidimensional meteorological factors such as precipitation, runoff and temperature, etc. The EEMD-LSTM prediction model is constructed by considering the characteristic relationship of hydropower power-meteorological factors and the time-series characteristics of hydropower power, and the model is trained by using the historical power data and meteorological data of neighboring power stations and the target power station. Finally, the model is analyzed based on the actual data of a basin hydropower plant. The results show that the proposed model can effectively improve the prediction accuracy of hydropower generation power.

The energy feasibility of using the heat and mechanical potentials of hydroelectric power stations water was determined using the developed expression of the energy efficiency criterion. Using the developed criterion were determined the areas and degree of application of combined electromechanical equipment, which excludes the repeated interconversion of electrical and mechanical energies.

The use of the clean natural/renewable energy resources has been promoted in the power generation, as those scarcely emit greenhouse gases. The waterpower has larger energy density than the wind power and the solar power, and there are many hydraulic power stations. The large-scale station with a dam, however, is undesirable because such public works damage natural ecosystem in rivers andlor forests. To promote more and more the hydroelectric generation for the next leap, it is necessary to utilize effectively mini/micro/nano hydropower in coexisting with natural ecosystem. This research develops a new type hydroelectric unit utilizing the yawing motion of the submerged blades in rivers, irrigation channels, and so on. In this report, the concepts of the unit are explained, and the output characteristics are discussed experimentally using the trial model.

The world began to search for new energy sources with increasing energy demand. Renewable energy sources are as hydropower important for alternative energy. Countries with high hydroelectric potentials continue to work to utilize hydroelectric power plants in the most efficient way. Pumped storage hydropower plants are an important investment to meet the growing energy needs at peak times and to store energy. Although it produces energy in many countries, pumped storage hydropower plants have not begun to be built in Turkey which has high hydroelectric potential. A new era will be opened for energy production in Turkey where a large number of pumped storage hydropower plants projects are in study phase with the construction of pumped storage hydropower plants and first nuclear power plant.

An assessment was made of the hydropower potential in Hawaii. The major conclusion of this study is that hydropower resources in the State of Hawaii are substantial, and they offer the potential for major increases in hydropower generating capacity. Hydropower resources on all islands total about 50 MW of potential generating capacity. Combined with the 18 MW of existing hydropower capacity, hydropower resources potentially could generate about 307 million kWh of electric energy annually. This represents about 28% of the present combined electricity needs of the Neighbor Islands, Kauai, Molokai, Maui, and the Big Island. Hydropower resources on Kauai equal 72% of that island's electricity needs; on Molokai, 40%, on the Big Island, 20%; and on Maui, 18%. The island of Oahu, however, has only small hydropower resources, and could only generate a negligible portion of its electricity needs from this energy source. A summary of existing and future (potential) hydropower capacities and estimated annual outputs for each island is presented. How much of the potential capacity is being actively considered for development and how much is only tentatively proposed at the time is indicated. The economics of hydropower at specific sites were analyzed. The major conclusion of this analysis is that hydropower development costs vary widely among the different sites, but that generally the cost of hydroelectric power is either less than or comparable to the cost of oil-fired power.
