Risk management for electrifying off-grid island using renewable energy microgrid

Renewable energy microgrids provide an economical and environmentally friendly solution to the difficulty of powering islands. However, due to the changing load, complex environment, intermittency of energy sources, and the immaturity of microgrid technology, island microgrids face many risks. In this study, a risk management system for island microgrids is established, the fuzzy analytic hierarchy process is used for risk assessment. Measures are proposed to mitigate risks, and their effect is quantified to make sure whether they are worthwhile. Finally, this method is applied to the Dongfushan Island Microgrid Demonstration Project. The result shows that the risk level of this microgrid project is relatively low risk. Among the many methods proposed, it is the most effective to reduce the risk of personnel accidents through measures such as publicity and education, which can make the microgrid the lowest risk level.
