Control of storage function of the reservoir
Hon, Matěj ; Matoušek, Petr (referee) ; Kozel, Tomáš (advisor)
Dispatcher graphs state the amount of discharged water according to the current status of a water tank. The thesis describes the technique of creating a zonal dispatcher graph and its simulation on a large open water reservoir Vranov. Using predictions, the model was tested to know how it works with the ability to determine incoming tributaries. The dispatcher graph method is commonly rated among deterministic control methods. These methods are advantageous in one specific output and that is a control variable. Other possible ways are stochastic methods that work with probability and give us the control over the choice of a procedure. Both types of methods are further described in the work. For the suitable prediction of flows, the use of a neural network operating on the principle of reverse propagation was chosen.

Control of the reservoir storage function using artificial intelligence methods
Hon, Matěj ; BBA, Šárka Zemanová, (referee) ; Kozel, Tomáš (advisor)
The diploma thesis deals with flow prediction using artificial intelligence to control the storage function of the reservoir. It focuses on the control of storage function using combination of dispatching graphs and flow prediction. The work is divided into a methodological part and an application part. The methodological part contain describes how the acquisition of historical data, a description of the work of dispatching graphs and forecasting models. The application part contains flow forecasts and outflow control. A prediction model is based on the fuzzy method, and it is used to predict inflows. The calibration and validation of the prediction model is also described. Results of prediction model were evaluated. In next step the results of control method were evaluated and compared with result of dispatching graphs. The results of controlled method were satisfactory.

Using a Hybrid Method for Control the Storage Capacity of the Dam Reservoir
Pospíšilík, Šimon ; Kozel, Tomáš (referee) ; Menšík, Pavel (advisor)
Bachelor thesis is focused on the selection of a suitable input regional climate model into the Hybrid method for the control of the storage function of water reservoirs. This control method is based on a suitable combination optimization method with the Support vector machines method. Selecting a suitable regional climate model is done by simulating the control of the storage function of water reservoirs Vír I in program Microsoft Exel. The simulation results of the hybrid control method are compared with other control methods. These methods are Adaptive control, Dispatcher graph, and control to Improved outflow.

Creating of Dispatcher Graph for a Selected Dam Reservoir Considering Climate Change
Hakl, Petr ; Sobek, Martin (referee) ; Menšík, Pavel (advisor)
The aim of a thesis is construct a several dispatcher graphs for a selected Vír I. water dam, from real flow series, then extended by synthetic flow series generated by regional climatic models. Particular models will be discribed, so the construction of dispatcher graph. Graphs will be compared by appropriately selected parameters. In the end of the thesis will be comparision of requirements sets by manipulate order with predicted evolution of affluent to the dam and sustainability for todays claims relation on improved outflows in future with the same condition.
