6 FAQs about [The working principle of energy storage wind pump]
What energy storage technology is used in hydraulic wind power?
This article mainly reviews the energy storage technology used in hydraulic wind power and summarizes the energy transmission and reuse principles of hydraulic accumulators, compressed air energy storage and flywheel energy storage technologies, combined with hydraulic wind turbines.
What is a hydraulic wind turbine energy storage system?
Perry Y. Li et al. first designed a new high-efficiency compressed air energy storage system for hydraulic wind turbines, as shown in Fig. 14. The principle is that the hydraulic power created by the pump in the nacelle drives the hydraulic transformer.
How does a wind turbine work?
The energy storage device (hydraulic accumulator) is connected to the output end of the wind turbine. The system absorbs energy fluctuations through the storage and release of seawater in the accumulator. At the same time, the entire system is directly connected to the grid through a synchronous generator without the need for a power converter.
Can energy storage be used in hydraulic wind power?
On one hand, introducing the energy storage system into hydraulic wind power solves the problems caused by the randomness and volatility of wind energy on achieving the unit’s own functions, such as speed control, power tracking control, power smoothing, and frequency modulation control.
Which energy storage mode should be used in a hydraulic wind turbine?
Battery energy storage and flywheel energy storage are mainly used for peak shaving and valley filling of system energy, which improves the quality of power generation. For the selection of the energy storage mode in a hydraulic wind turbine, when solving the problem of ‘fluctuating’ wind energy, hydraulic accumulators should still be the mainstay.
How does a wind turbine energy storage system work?
The energy storage system is connected in parallel with a traditional wind turbine at the input of the power grid. When there is a surplus of system energy, the system stores the excess energy in the flywheel through the AC/AC converter and the hydrostatic transmission system (pump-motor system).
