Abstract:V delu je predstavljena kratkoročna optimizacija obratovanja verige Dravskih elektrarn. Optimizacija temelji na genetskem algoritmu, ki je del programskega paketa MATLAB. Predstavljeni so postopki modeliranja hidroelektrarn in bazenov. Uporabljeni so nelinearni modeli hidroelektrarn in dinamični modeli bazenov. Parametri dinamičnih bazenov so določeni na podlagi izmerjenih vrednosti pretokov in nivojev vode v bazenih. Za model verige dravskih elektrarn so prikazane primerjave med izmerjenimi in izračunanimi časovnimi odzivi nivojev vode v bazenih. Z analizo izmerjenih vrednosti moči v obdobju enega leta je bilo zmanjšano število možnih rešitev optimizacije. Časovno obdobje optimiranja je omejeno na največ 24 ur.

Title:SHORT TERM OPTIMIZATION OF DRAVA RIVER HYDRO POWER PLANTS OPERATION
Abstract:This work presents short term optimization of Drava river hydro power plants operation. Optimization is based on genetic algorithm, which is part of MATLAB software package. Modeling of hydro power plants and basins is presented. Nonlinear models of hydro power plants and dynamic basins are used. Parameters of dynamical basin models are obtained on measured values of flows and water levels. Calculated and measured time responses of basin water levels are compared for entire chain of Drava river hydro power plants. A mathematical analysis of measured powers within one year operation periode is used to reduce the possible solutions of optimization. Period of optimization calculations is limited to maximum of 24 hours.
Keywords:short term optimization, hydro power station, basin, workflow, model, genetic algorithm
