Abstract: The complex interplay between cost, energy, and exergy, in trigeneration and cogeneration systems when compared to power only systems, is yet to be resolved under varied proportions of heating to cooling loads. After an overview of research on the modelling and optimisation of cogeneration systems, the effects of satisfying highly dynamic electric, heating, and cooling loads are analysed in stand-alone hybridised mode, a concept not commonly tackled in the literature. The sensitivity of performance in this Micro Gas Turbine/PV system under, multi-objective (double, triple) optimisation functions is also addressed in terms of Cost of Energy (COE, $/kWh), overall energy efficiency (η, %), and exergy efficiency (ηex, %). Varied capacities of Micro Gas Turbines (30 kW and 65 kW) are included in the MATLAB based Genetic Algorithm under CHP or CCHP mode.
