Abstract

The present state of the electrical grid is unable to meet the demands of transmission. Digital twin technology provides a promising solution to this problem by allowing for analysis and control of distributed energy resources. This thesis presents initial work towards development of a digital twin for a DC power system. Two versions of the DC power system are created and evaluated against randomly generated load profiles. System performance is evaluated on the basis of the quantity of the load that is unserviced by the generation and energy storage. Energy storage operating strategies that modify the model to prioritize different aspects of the system are introduced, along with a discussion of the effects of the modifications. A preliminary optimization function is discussed that will be used to control the system. From this optimization function, key information that is needed for the digital twin can be determined. This work also introduces two additional works that will require adjustments as the digital twin is developed. The first measures the ability of the system to withstand disturbances. The second presents a decision matrix to examine the trade-off between the number of pulses that the system is capable of producing and the magnitude of those pulses.
