Correlation between the precipitation and energy production at hydropower plants to mitigate flooding in the Missouri River Basin
Currently, hydropower plants serve as one source of green energy for power companies. These plants are located in various geographical regions throughout the United States and can be split into three main classifications: run of river, basins, and reservoirs. The energy production at hydropower …

Cost comparison of hydropower options for rural electrification in Rwanda
The decision to develop a hydropower plant depends on several factors, which cost is the most significant. This thesis, entitled "Cost comparison of hydropower options for rural electrification in Rwanda" intends to show that the use of a large number of mini hydropower plants for electrification …

Minimizing the detrimental effects of hydro-peaking on riverbank instability: The lower Osage River case
… of water level downstream from dams due to hydropower flow releases negatively affects the riverbank stability. Therefore, this research aims to examine the feasibility of using an optimization technique to mitigate the riverbank instability resulting from the outflow variation of hydropower …

Hydropeaking in Alpine rivers: an ecosystem services approach
… services. The release of water from storage hydropower plants generates rapid flow and stage fluctuations (hydropeaking) in the receiving water bodies at a variety of sub-daily time-scales. In this thesis, we describe an approach to quantify such variations, which is easy to apply, requires …

The Brazilian electricity market : small hydropower strategic planning
… than 70% of its installed capacity coming from hydropower puts Brazil in a great position in terms of reduced environmental impact on electricity generation. However, it also creates a large supply dependency on weather, water flows and reservoirs. In the last 2-3 years, the country has been …

Multicriteria Decision Method for Renewable Energy Production: Siting Solar, Wind and SHP Plants in Zimbabwe
… locations for renewable energy production plants in Zimbabwe. The first step in the process was to define suitability criteria for siting wind, solar and small hydro power plants. Vector and raster data sets corresponding to the criteria were gathered and a geodatabase was constructed. The …

Phasor Measurement Unit (PMU) : based system for event detection on synchronous generators
Unusual generator events are sometimes seen in the Phasor Measurement Unit (PMU) data in the Icelandic power system, probably due to the small size. The use of PMU data with event detection algorithms, along with modeling, could be a method of capturing these events for analysis. The goals of this …
