The paper studies grid-connected photovoltaic (PV)-hydrogen/battery systems. The storage componentcapacities and the rule-based operation strategy parameters are simultaneously optimized by theGenetic Algorithm. Three operation strategies for the hydrogen storage, namely conventional operationstrategy, peak shaving strategy and hybrid operation strategy, are compared under two scenarios basedon the pessimistic and optimistic costs. The results indicate that the hybrid operation strategy, whichcombines the conventional operation strategy and the peak shaving strategy, is advantageous in achievinghigher Net Present Value (NPV) and Self Sufficiency Ratio (SSR). Hydrogen storage is further comparedwith battery storage. Under the pessimistic cost scenario, hydrogen storage results in poorer performancein both SSR and NPV. While under the optimistic cost scenario, hydrogen storage achieves higher NPV.Moreover, when taking into account the grid power fluctuation, hydrogen storage achieves better performancein all three optimization objectives, which are NPV, SSR and GI (Grid Indicator).
