Estimation of passivity margins of hydrogen-based hybrid renewable energy systems via energy tanks

This paper proposes new tools to design models and controllers for power systems. Within the port-Hamiltonian modeling framework, concepts that extend passivity margins and energy tanks are used to estimate power reserves in Hybrid Renewable Energy Systems. The methodology is applied to multi-source cells with renewable energy dedicated to the production of clean hydrogen. This work can be extended to more complex networked power systems, with the aim to increase the reliability of standalone networks by fitting the power demands while avoiding damage and extending lifetime of the equipment.
