【 摘 要 】

Solar energy is one of the renewable energies that has been proved to be a practical way to solve the present energy crisis and achieve sustainable development. However, in Thailand, the Concentrating Solar Power (CSP) technologies are inappropriate for power generation because the annual direct or beam solar radiation is low. In this study, the concept of a solar Organic Rankine Cycle (SORC) system for power generation with temperature below 100 °C is proposed. The system is analyzed by using a 60 kWeORC power generation with R-245fa as working fluids in combination with solar water heating system (SWHS). Compound Parabolic Concentrating (CPC) solar collectors were used to generate heat. These systems were mathematically modelled and simulated to evaluate the maximum power output, the CO2 emission, and levelized cost of electricity (LCOE). Bangkok represented as the central part of Thailand were taken as the weather data of the simulations. The results found that, a SORC power plant is appropriate for below 100 ˚C heat source. The ORC system is a good solution for power generation from low-temperature heat source. Moreover, when 1,680 units of CPC solar collectors combined with a 60 kWe ORC power generation and size of the thermal energy storage (TES) of 50,000 liters, the system were the lowest LCOE of 0.915 USD/kWh, the system can generate the power output of 159.9 MWh/Year and can reduce CO2 emission of 88 Ton CO2 eq./Year.
