The performance evaluation of a grid-tied microgrid with hydrogen storage and a hydrogen fuel cell stack

摘要

In a heat-power system, the use of distribute energy generation and storage will improve system’s efficiency, reliability, and emission. This work is focused on the comprehensive performance evaluation of a grid-tied microgrid, which consists of a PV system, a hydrogen fuel cell stack, a PEM electrolyzer, and a hydrogen tank. The performance indexes of this microgrid are compared with one without energy storage or a fuel cell stack. As a result, the environment effect and the service quality in the first system is higher than those in the second one. But they both have the same overall performance index.
