The system comprises a power generation unit for providing energy power supply, an energy storage unit forstoring energy and a load unit for consuming energy by an offshore island; and the power generation unit comprises a hydrogen fuel cell, the energy storage unit comprises a hydrogen compression moduleof an electrolytic hydrogen production system, and the load unit comprises an electrolytic hydrogen production system complete device and a hydrogen storage system power utilization module. The powergeneration unit also comprises a photovoltaic power generation system, a wave energy generator set, a wind generator set and a tidal generator set; the photovoltaic power generation system is configured and distributed on the roof of a building on an island and a wide region on the island, the wave energy generation device is arranged in a sea area around the island, the wind generator set is arranged on an offshore tidal flat and a high-altitude mountain top on the island, and the tidal generator set is arranged at a high-altitude valley by the sea; and the load unit also comprises an external network load.

Description

technical field [0001] The invention relates to the technical field of energy utilization, in particular to an island integrated energy system based on hydrogen fuel cells and a control method thereof. Background technique [0002] The characteristics of isolated islands on the sea are: on the one hand, they are weakly connected with the external power grid, the external power is unstable or difficult to supply continuously, and the supply of fresh water and energy is insufficient; on the other hand, they have relatively rich seawater and clean energy resources, such as tidal energy, solar energy, wind energy etc. Due to the particularity of isolated islands at sea, there is no system in the prior art to use the resources of isolated islands at sea for the particularity of isolated islands at sea, resulting in the lack of development of their own resources, but the isolated islands are facing the problem of insufficient energy supply. [0003] Based on this, there is an urg...

AI Technical Summary

Problems solved by technology

[0004] The invention provides an island comprehensive energy system based on hydrogen fuel cells, which uses hydrogen fuel cells as the core and also includes photovoltaic power generation systems, wave energy generators, wind power generators and tidal generators to generate electricity to solve the problem of isolated islands at sea. Resources are lack of development, but isolated islands are facing the problem of insufficient energy supply, so as to realize the comprehensive utilization of hydrogen energy, wind energy, tidal energy, wave energy, and solar energy in the isolated island environment, and can take into account the supply of fresh water and hydrogen energy on the isolated island. its own energy resources, to solve its own energy supply problems
