Description

Technical field

The present invention relates to the technical field of offshore storage equipment, and in particular to a multi-energy complementary storage system and a control method thereof.

Background technique

Cold storage is a storage facility that mainly stores items that have a short lifespan and are very likely to deteriorate under normal conditions. Traditional cold storage uses mechanical refrigeration by refrigerators, using liquid coolants (such as ammonia) with very low vaporization temperatures to evaporate and absorb heat inside the storage to achieve cooling. This consumes a lot of electricity and is highly dependent on power supply from the grid.

However, the power conditions in remote areas such as mountainous areas, islands, and offshore platforms are not sufficient for the operation of traditional cold storage. The cold storage on the offshore platform is mainly used to preserve the freshness of breeding feeds such as small fish. After the feed is transported to the offshore platform in batches, it needs to be properly refrigerated and stored in the cold storage to ensure the continuous supply of feed and the quality of breeding.

Currently, cold storages on offshore platforms are powered by solar power or batteries. However, solar power generation is easily affected by regional and climatic conditions, and battery power supply is still unstable and discontinuous. Neither solar power generation nor battery power supply can provide continuous and stable power for the cold storage of offshore platforms, resulting in poor operational stability of the cold storage, which in turn affects the quality of the feed stored in the cold storage.
