摘要: Solar Dish Micro Gas Turbine (MGT) systems have the potential to become interesting small-scale power plants in off-grid or mini-grid contexts for electricity poly-generation production. The main challenging component of such is solar receiver which should operate at high temperatures with concentrated radiations, strongly vary time. This paper deals design and analysis a novel integrated short-term storage system based on Phase Change Materials prevent sudden variations maximum temperature MGT working fluid. Particularly, charge discharge behavior was analyzed by means Computational Fluid Dynamic methods evaluate potentiality concept capabilities. Achieved results were highly satisfactory: has good thermal inertia can relevant fluctuations fluid 20–30 min.
