Abstrakt
The article presents an extended model of the Solina-Myczkowce pumped storage power plant with the designed new reservoir and Jawor power plant. Different design cases for the size of the reservoir located on Mt. Jawor were considered. In building the model, a modular approach was used to clearly distinguish elements of the model. In order to capture seasonal changes in both hydrological conditions and power demand values, a period of 365 days was assumed for the simulations. The simulations assumed the form of criteria defining on/off moments and defining the turbine/pump turbine operating regime using the daily variation of energy prices. All constraints arising from the physical parameters and limitations of the cascade facilities as well as those arising from the provisions of the current Water Management Manual for the Solina-Myczkowce cascade were taken into account. The model was designed and executed using the Matlab-Simulink interface. The developed model, assuming various solutions of the additional Jawor-Solina pumped storage power plant, allows multivariate analysis of the effects, both in the sphere of electricity production and financial . The flexible design of the model is a proposal with the help of which it is possible to develop and test decision-making mechanisms in the energy and financial area of cascade operation. Expansion of the energy cascade with a new element of the pumped storage power plant affects the functioning in its current form of the Solina-Myczkowce PSPS. The results show the directions of changes that should be made in the operating strategy of such an expanded energy complex. The analyses are supported by a number of charts and a commentary.
