Offshore wind power floating foundation integrated with electrochemical energy storage device

Abstract

An offshore wind power floating foundation integrated with an electrochemical energy storage device comprises a floating supporting platform, a gravity type anchoring structure and the electrochemical energy storage device, the lower portion of the floating supporting platform is connected to the gravity type anchoring structure through a mooring cable, and a wind driven generator is located on the upper portion of the floating supporting platform and connected with the floating supporting platform. The electrochemical energy storage device is located in the gravity type anchoring structure and connected with the wind driven generator through a cable, and the submarine cable is connected with the electrochemical energy storage device and led out of the gravity type anchoring structure to be connected with a power grid. The electrochemical energy storage device performs real-time adjustment or periodical adjustment on electric energy input to the power grid by the wind driven generator according to power output characteristics of the wind driven generator. The offshore wind power floating foundation has the characteristics of simple structure, good stability, good adaptability and capability of effectively reducing or eliminating the impact of overlarge fluctuation of the existing offshore wind power on a power grid.

Description

technical field [0001] The invention belongs to the technical field of offshore floating wind power, and relates to an offshore wind power floating foundation integrated with an electrochemical energy storage device. Background technique [0002] As the country promotes carbon neutrality, clean energy such as offshore wind power will become an important part of the national energy system. However, the output power of wind turbines is closely related to the wind speed. Due to the influence of wind speed fluctuations at sea, the output power of wind turbines is not stable, and has the characteristics of intermittent and randomness. At present, the development of offshore wind power in China is relatively small, and the volatility of wind power has no significant impact on the stability of the power grid. However, with the large-scale development of offshore wind power, solving the volatility of offshore wind power will become the key to absorbing offshore wind power. The deve...

Problems solved by technology

If the energy storage power station is built on land, it will occupy a large land area. If it is built on the sea, a dedicated platform needs to be built, and the cost is relatively high

As offshore wind farms move from near seas to deep seas, the foundation of offshore wind farms will also be based on floating foundations, and the construction of floating platforms for energy storage power stations will be a huge investment
