Using control methods to model energy hub systems

Abstract

In this paper, multi-carrier energy system (MCES) optimization problem is solved by using Similar Decoupled Form (SDF) energy hub modeling. Compared with the traditional energy hub modeling method, the Similar Decoupled Form modelling method improves flexibility and automation of the energy hub system. More importantly, energy hub does not need to be linear when using this method. In other words, the limitations of SDF are greatly reduced and it can be used in a more general energy system with energy storage equipment. This method can be used to analyze power flow from both sides of the energy hub (input side and output side) and the stability of the energy hub system. Finally, SDF shows the dynamic change of the energy hub system rather than only the result of mathematical optimization.
