Flow battery energy storage system for wave power generation

Abstract

The invention discloses a flow battery energy storage system for wave power generation. The flow battery energy storage system comprises a charge device which is connected with a wave power generation device, a galvanic pile group which is connected with the charge device, and an electrolyte storage device which is connected with the galvanic pile group through a pipeline system, wherein the electrolyte storage device comprises a positive electrode electrolyte storage tank and a negative electrode electrolyte storage tank; a flow battery system is formed by the galvanic pile group, the pipeline system and the electrolyte storage tank; the charge device is used for charging the flow battery system by virtue of the electric energy output from the wave power generation device; after being separated from the galvanic pile group, the electrolyte storage tank can be loaded and transported away through transportation equipment. The flow battery energy storage system is used for achieving on-site storage, effective transfer and targeted release of electric power converted from wave power, and is relatively flexible and reliable when being compared with a power transmission mode by virtue of seabed cables.

Problems solved by technology

However, due to the constraints of technology and cost, wave energy power generation technology has not been applied and developed on a large scale. The wave energy power generation in the prior art uses the mechanical energy generated by wave motion to drive the generator to generate electricity, and then transmits the electric energy to the The shore is connected to the power grid to achieve power supply. The existing problems are: the use of submarine cables for power transmission is expensive, the cable is too long, the line loss is large, the transmission efficiency is low, and there is a risk of scratching and damage to the submarine rock cable. , the wave power station in the prior art can only be built near the coast, which restricts and restricts the operation of the wave power station from offshore to the inland sea where wave energy is more abundant, and the power generation capacity is not strong. At the same time, long-term use of submarine cables will cause Problems such as aging and damage, and cables can only be powered point-to-point, resulting in a relatively single load, which cannot meet the power supply needs of multiple islands or loads for a set of wave energy power generation equipment
