TY - JOUR TI - Models of thermal processes for design optimization of power plants based on renewable energy sources and fuel cells AU - Grigoriev Alexander S AU - Skorlygin Vladimir V AU - Grigoriev Sergey A JN - Thermal Science PY - 2019 VL - 23 IS - 2 SP - 1225 EP - 1235 PT - Article AB - The system of mathematical models of thermal processes in hybrid power plants based on solar and wind renewable energy sources and methanol fuel cell has been developed to be used for the power plant design parameters optimization. Main assumptions and main equations for the heat and mass exchange in power plant are presented, methods and verification results for the power plant operation are given. Power plant design optimization and operation modes are discussed as well as experimental data collected during power plant operation. Forecast example for temperature fields during low ambient temperature operation is shown.
