Performance of a SOFC/GT hybrid system (HS) were analysed by a dynamic model. HS control strategy is prosed to follow a daily Micro-Grid load demand. Model regulates SOFC temperature at a fixed value adjusting air utilization factor. HS partialization was carried out either by GT that through SOFC part-load. 54.5% HS daily efficiency and a part-load degree up to 42.8% are reached.
