Computer-Aided Method for Simulating the Operation of an Energy System, and Energy Management System

摘要

Various embodiments include a computer-aided method for simulating the operation of an energy system with a component comprising: modeling the energy system as an optimization problem with energy consumptions and energy outputs of the component and respective shadow prices associated with the energy consumptions and energy outputs as optimization variables; calculating the energy consumptions, the energy outputs, and the respective associated shadow prices by numerically solving the optimization problem; calculating a first sum of the energy consumptions weighted with the associated shadow prices; calculating a second sum of the energy outputs weighted with the associated shadow prices; calculating an incorrect dimensioning variable of the component by subtracting the second sum from the first sum, and using the investment costs and operating costs of the component; and determining overdimensioning or underdimensioning of the component as a function of the calculated incorrect dimensioning variable.
