Estimation of the active storage of reservoirs for energy production, in a changing climate.

Toliopoulos, Christos

The theme of the present thesis is the estimation of the active storage of reservoirs for energy production, in a changing climate. The watershed of Pili, which is located in Thessaly, selected as the study area. The entire research is based on the specific charac-teristics of this region. For starters temperature and precipitation data, expressed in mean monthly values, collected and processed. The mean precipitation at the mean altitude of the basin is estimated by utilizing the Thiessen polygon method. The aforementioned polygons engraved in QuantumGIS (QGIS2.16.1) and five sub regions are formed. Temperature data, processed by means of the temperature lapse rate. The purpose of the previous work was the preparation for the implementation of the hydrological model. UTBAL model, which is a lumped hydrological model applied, calibrated and validated with real discharge data in order to simulate the monthly runoff of the basin. The next step for the estimation of the active storage of the basin of Pili was the implementation of the Rippl method, the Dincer method and the Stall method. Three different schemes of water demand considered and compared to each other in order to have a quantitative approach for the problem of energy production. Furthermore, the dead storage of the reservoir assessed by the means of Gavrilovitz technique. The results show that the pro-duced energy for the installation, located at the basin of Pili, is equal to 52.5 gigawatts hours (GWh). A climatic scenario in order to simulate the climatic changes for the up-coming one hundred years considered and the regional climatic model KNMI-RACMO2 implemented. The temperature and precipitation data for the region of Pili were evaluated via the climatic model and the aforementioned methodology regarding the estimation of the active storage, dead storage and the produced energy, repeated step by step.
