Simulation of central receiver solar thermal power plant with inclusion of storage tank.
Abstract
Mathematical modeling is done for the external central receiver solar thermal power plant. Code is developed for the same and simulation for performance of plant is done by using Visual Basic. In this plant configuration, external receiver receives the incident solar radiation reflected by heliostats. Thermal losses are determined in the receiver and net thermal power from receiver is stored in storage tank. This stored thermal energy is further used to run the turbine. Here effect of inclusion of storage tank on electrical power generation is studied by simulation. Three days namely, cloudy day, winter day and summer day are studied for variation in thermal energy storage. Simulation is also done for the annual power generation with zero hours, eight hours and twelve hours of storage. Comparison is made between effect of increase of concentration ratio and utilization of thermal energy in power plant.
