As wind energy cannot be directly stored, for off grid wind power generation system, in order to ensure the stability and reliability of power supply, customized wind energy storage Manufacturers china for other devices during windy periods. Even in areas rich in wind energy resources, if wind power generation is the main way to obtain electric energy, it must be equipped with an appropriate energy storage system for customized wind energy storage Manufacturers china. Moreover, when wind power and other energy sources are jointly used for power supply, wind energy storage technology is also required. Three energy storage modes of customized wind energy storage Manufacturers china:

1. Battery

The wind turbine usually uses the battery for customized wind energy storage Manufacturers china when it is operated complementarily or independently with other power generation devices. In the combined operation of wind power and diesel power generation system, the measures of short-term wind energy storage with batteries can avoid frequent starting and stopping of diesel engines due to changes in wind power and load. In addition, the battery can also reduce the light load operation of the diesel engine, so that most of the time it runs in a more appropriate power range. Similarly, battery is also used as the main energy storage mode in wind solar complementary power generation. In view of the cost of battery, lead-acid battery or alkaline battery is often used as customized wind energy storage Manufacturers china device in wind power generation system.

2. Superconducting energy storage

The United States began to study the feasibility of developing superconducting coil energy storage in the 1990s. Superconducting coil is one of the best choices for customized wind energy storage Manufacturers china because it can flow high current with extremely high current density at superconducting temperature without consuming electrical energy. Superconducting energy storage can absorb or emit active and reactive power, with fast response and large capacity, which greatly reduces the loss of the circuit.

Superconducting energy storage technology is used for customized wind energy storage Manufacturers china to stabilize the output voltage and frequency of wind turbine generator, so as to stabilize the power grid. Based on the detailed introduction of the regulation principle and optimal control method of superconducting magnetic energy storage (SMES) according to the online information, a SMES model is proposed in the grid connected wind power generation system, and the genetic algorithm is used to optimize the control parameters of SMES. The simulation results show that SMES can realize the simultaneous control of voltage and frequency in the grid connected wind power generation system, and improve the output stability.

3. Uninterruptible power supply (UPS)

Uninterruptible power supply (UPS) refers to a device that can continue to supply power to the load and ensure the quality of power supply so that the load power supply will not be affected when the AC input power supply is abnormal or disconnected. Modern UPS generally adopts pulse width modulation technology, IGBT, power M0SFET and other modern power electronic devices, which improves efficiency and reliability. The microprocessor software and hardware technology is introduced to realize intelligent management, remote maintenance and remote diagnosis. The randomness of customized wind energy storage Manufacturers china is large, and the stability of power generation is also limited. For more remote areas or wind farms operating independently, it is necessary to use wind energy storage for UPS.

The above is the way of customized wind energy storage Manufacturers china. I hope you can have a better understanding of the way of customized wind energy storage Manufacturers china.
