Hybridized gas turbine cycles are attractive because of their high efficiency, potentially equal to combined cycle efficiency, and dispatchable power capability. TES technologies are important to accelerate marketpenetration of CSP plants, overcoming the limitation due to the intermittence of the solar source.In this work a high temperature ceramic storage Test rig for gas turbine energy systems was presented with its innovative layout, which avoids the use of hot valves. Such experimental plant storage is located at the University of Genoa, Savona Campus, Italy: it can be run with compressed air and it is ready for connection with the modified microturbine T100 onsite. The Test rig represents a scaled-down version of a larger system designed for an hybridized solar 12 MW gas turbine whose dynamics performance was presentedpreviously. This paper presents the dynamic analysis of such lab-scale mGT system, which provided the necessary requirements for the Test rig design.The storage system proposed here does not involve any hot air valve and does include a short-term (30min equivalent) ceramic thermal storage. The plant dynamic model was developed using the original TRANSEO simulation tool. This paper investigates plant layout control strategy, showing the feasibility of the control procedure through dynamic simulation: eventually, design recommendations are drawn to improve plant flexibility and time response.
