Multiple hybrid storage systems operation with combined fuzzy logic and model predictive control considering two-dimension modeling

Abstract

Hydrogen storage system operates as the long-term storage system, which will play an important role in future smart cities. In the hydrogen storage system, fuel cell, hydrogen tanks, and electrolyzer are combined together, and they often operate with complex electrochemical reactions. How to efficiently operate the hydrogen storage system, and at the same time consider the related electrochemical reactions is a problem. On the other hand, multiple hydrogen storage systems are often grouped together to supply the demands, and to cooperate these storage systems is another complex problem. In this paper, we presented a two-dimension model of hydrogen storage based microgrid, and a combined fuzzy logic and model predictive control (MPC) method is used to cooperate the multiple storage systems. The simulation results show that the dispatched power is first allocated to hybrid storage systems considering each storage system conditions, and second scheduled to battery storage and hydrogen storage based on MPC method.
