摘要

In the scenario of the small scale 3-35 kWe concentrated solar power plant based on point receiver technologies; the dish-Stirling configuration is one of the most commonly adopted one. New and clean efficiency of these Stirling engines is typically of 30-40%. Yearly average efficiency, during the system operations, is significantly reduced to 10-15% due to the Stirling engines high maintenance costs and poor reliability issues. These drawbacks limit the small scale dish-Stirling engines market attractiveness. The adoption of cheap, reliable and widely available engines, such as micro gas turbines is a promising solution for substituting Stirling engines since it ensures constant performance over time. Since micro gas turbines for concentrated solar power plant: equipped with dish concentrator have not been widely deployed, the development of a plant simulator is helpful for predicting the overall concentrated solar power plant performance and for optimizing the plant operation: under different boundary conditions. The plant simulator is aimed to demonstrate the economic viability and the technical feasibility of dish - micro gas turbine systems.
