Analysis of Electric Disturbances from the Static Frequency Converter of a Pumped Storage Station
… disturbances created in the electric system of a pumped storage power plant, which is an hydraulic generation facility where the machines can work as turbines or pumps, by the operation of a static frequency converter (SFC). The SFC is used for starting the synchronous machines at the station when …

Linear Power Discretization and Nonlinear Formulations for Optimizing Hydropower in a Pumped Storage System
Operation of a pumped storage system is dictated by the time dependent price of electricity and capacity limitations of the generating plants. This thesis considers the optimization of the Smith Mountain Lake-Leesville Pumped Storage-Hydroelectric facility. The constraints include the upper and …

Improvements to a key contributor of frequency control : the co-ordination of guide vane operation in a pumped storage plant
… this, the co-ordination of the guide vanes at pumped storage plants was selected. Pumped storage units exhibit a non-minimum phase characteristic which can negatively affect the frequency response on the grid. Attempts were made to improve this system’s contribution to frequency control. To …

Feasibility of retrofitting existing hydropower infrastructure for use in renewable energy storage
Pumped storage is the only mature grid-scale energy storage technology. Originally developed to support nuclear base load plants due to its ability to store energy on the scale of gigawatt-hours (GWh) and rapidly respond to demand fluctuations, pumped storage is recognized as a viable option to …

A methodology to assess the interactions of renewable energy systems dynamics with fluctuating loads
… hydro availability and generating capacity, and pumped-storage scheduling are not adequately represented in this process. These are real problems and their solutions are sought in this dissertation. Finally, the value of PV systems does not lie only in serving load, but also in reducing problems …

Induction heating of firebricks for the large-scale storage of nuclear and renewable energy
The lack of low-cost, large-scale energy storage is one of the biggest obstacles to the ongoing transition from an energy market dominated by fossil fuels to one dominated by nuclear and renewable energy. Storing energy as heat in firebricks has a number of potential advantages over existing energy …
