| Abstract: |
| The strong fluctuation of renewable energy will lead to the life decay acceleration of electrolytic cell and battery in the distributed electric-thermo-hydrogen system. In order to extend the service life of electrolytic cell and battery while improve the economy of distributed electric-thermo-hydrogen system, an optimal scheduling strategy for distributed electric-thermo-hydrogen system is proposed considering the life decay characteristics of electrolytic cell and battery. The life decay characteristics of electrolytic cell and battery are analyzed, and the life decay models of electrolytic cell and battery are established. Taking the comprehensive improvement of the life of electrolytic cell and battery and the system economy in the distributed electric-thermo-hydrogen system as the optimal object, an optimal scheduling model of distributed electric-thermo-hydrogen system considering the life decay characteristics of electrolytic cell and battery is established, and the scenario generation method is used to deal with the uncertainty of renewable energy and load. A distributed electric-thermo-hydrogen system containing a variety of energy conversion and sto-rage devices is taken as an example for simulation, and the results verify the effectiveness of the proposed strategy. |
