The concentrated solar power system with Stirling technology in a micro-grid: the simulation model

The electricity has a predominant importance in everyone's life: no one can do (live) without it. However, this involves the use of raw materials, which except for a few cases, come from nonrenewable fossil fuels. It becomes need therefore be able to take full advantage of the energy contained in the fuel, creating cycles that allow to use the energy released from oxidation and maintaining contained losses. The cogeneration starts as a solution to this problem, obtaining energy either in the form of electrical energy (or mechanical) either in the form of thermal energy, and then dispersing with the gas still hot at the end of the cycle only a minimal part of the calorific value of the fuel. In particular, the concentrated solar power technology, actually, presents advantages over other renewable source technologies from the point of view of its integration in to the grid and electricity markets. This methodology can be used both on large systems or on smaller modest, up to even the domestic cogeneration in the context of a Micro-grid favoring also the integration of variable renewable energy sources. In this paper, the attention is focus on the implementation of a simulation model in Matlab/Simulink environment of a concentrated solar power system with Stirling technology.
