Glossary ======== .. list-table:: :header-rows: 1 * - Name - Description * - model parameter - A feature in the model that is not controlled by the designer, but affects the model outputs, i.e. the solar irradiance. * - design variable - A feature in the model that is controlled by the designer and affects the model outputs, i.e. the capacity of the photovoltaic array. * - quantity of interest - The model output of interest, for which the stochastic features are quantified, i.e. mean, standard deviation, Sobol' indices. * - population - The set of design samples considered during the design optimization. * - fitness - The objective values for the design samples considered during the design optimization. * - objective - The goal of the optimization, i.e. the minimization of the carbon intensity mean. * - Sobol' indices - Sensitivity indices which quantify the contribution of the variance of the model inputs to the variance of the quantity of interest. * - hydrogen-based energy system - An energy system that produces and uses hydrogen as an energy carrier.
