Event-triggered decentralized coordinated control method for economic operation of an islanded electric-hydrogen hybrid DC microgrid

Due to the integration of hydrogen energy system increases the complexity and diversity of DC microgrid (MG) economic operation, economic power split and reliable operation become significant control issues. This paper provides an event-triggered decentralized coordinated control method for an islanded electric-hydrogen hybrid DC MG. For the implementation economic operation of this DC MG, an operating cost function with real-time efficiency is constructed by analyzing the operation characteristics of the subsystem. On this basis, an improved economic control strategy based on cost function is designed under the event-triggered framework, driving the electric-hydrogen hybrid energy storage system to execute the corresponding scheme for economical and reliable operation. The results of the RL-LAB experimental platform show that the proposed decentralized method is economically beneficial and effective in ensuring reliability in different scenarios.
