The thesis analyzes the impact of increased capacity of thermal energy storage on the operating characteristics of a medium sized heating plant for heating approximately four thousand households. In the initial part, the theoretical basis of cogeneration of heat and electricity and types of cogenerations are given. Afterward, the theory of caloric energy storage is discussed. A description of the cogeneration devices in the studied city heating plant and the characteristics of combined production of heat and electricity is presented next. In the main part of the thesis, the calculation and analysis of operation with increased capacity of thermal energy storage is conducted. Real operating data with hourly consumption of heat, electricity production and temperatures in the thermal energy storage tanks were used for the calculations.
