Abstract

An ocean buoyancy energy storage system belongs to the technical field of energy storage. It solves the problem that the structure of the existing buoyancy energy storage system is complex, which is not conducive to the realization of large-scale energy storage clusters. The present invention comprises electric motor, generator, first clutch, second clutch, buoyancy ball, closing cable, parking track, first winch, second winch and grasping device; The ball descends from the sea surface platform to the seabed, and converts the excess electric energy into potential energy for storage; when power generation is required, the buoyancy ball floats from the seabed to the sea surface platform and drives the generator to generate electricity through the closed cable. The whole system has a simple structure and can generate electricity. The surplus power is efficiently converted into potential energy for storage, and the energy conversion rate is high. The invention is mainly used for energy storage and power grid peak regulation and frequency regulation, etc., and can also be used for energy storage of offshore wind farms.

Description

technical field [0001] The invention belongs to the technical field of energy storage. Background technique [0002] The development of marine renewable energy is in the stage of rapid development, and it is bound to become an important part of the future sustainable energy structure. In addition to the successful operation of large-scale shallow-sea fixed wind power projects, offshore wind power will develop to deep-sea in the future. There are already a large number of built, under construction and planned floating wind power projects in Europe, the United States and Japan. On land, large-scale photovoltaic arrays need to occupy a lot of land resources, which is often unacceptable in economically developed and densely populated coastal areas. Research on floating photovoltaic power generation system on water. Compared with onshore photovoltaic systems, it can use the surrounding low-temperature water to prevent overheating of solar cells, and it is not easy to cause dust...
