Small-Scale Concentrated Solar Power Plants could have a potential market for off-grid applications in rural contexts with limited access to the electrical grid and favorable environmental characteristics. Some plants already been developed, like 25-30 kWe Dish-Stirling engine. Other ones are under development as, example, based on Parabolic Trough Collectors coupled Organic Rankine Cycles. Furthermore, technological progress achieved of new small high-temperature solar receiver, makes possible interesting systems Micro Gas Turbines Dish collectors. Such several advantages terms costs, reliability availability if compared plants. In addition, Dish-Micro Turbine expected higher performance than Cycle plants.The present work focuses attention some challenging aspects related design receivers systems. Natural fluctuations radiation can reduce system damage seriously Turbine. To stabilize operation, receiver has assure proper thermal inertia. Therefore, integrated short-term storage phase-change materials is proposed this paper. Steady-state transient analyses (for charge discharge phases) carried out using commercial CFD code Ansys-Fluent. Results presented discussed.
