Wind energy is an inexhaustible and inexhaustible renewable clean energy, clean, environmentally friendly, and renewable. According to relevant data, the theoretical reserves of China’s terrestrial wind energy resources are 3.226 billion kw, and the exploitable wind energy reserves are 2.53. 100 million kw, coastal and islands with rich wind energy resources, its developable capacity is 1 billion kw. As of 2013, the national grid-connected wind power installed capacity was 75.48 million kilowatts, an increase of 24.5% year-on-year, and the installed capacity ranked first in the world; the national grid-connected wind power The power generation was 140.1 billion kWh, a year-on-year increase of 36.6%, which was higher than the growth rate of wind power installed capacity in the same period. With the country’s emphasis on environmental protection, the energy crisis, the continuous decline in installed costs and other factors, as well as the successive introduction of wind power support policies, wind power will usher in a leap-forward development, which makes the shortcomings of wind power increasingly prominent. As we all know, wind energy has the characteristics of intermittent and randomness. When the wind speed changes, the output power of the wind turbines also changes. There may be no wind at the peak of electricity consumption, and the wind is very large when the available electricity is low, which affects the grid. In the normal operation of wind power, it is difficult to coordinate the supply and demand of wind power, and the phenomenon of “wind abandonment” is very common, which makes the effective utilization hours of wind power very low. The key to solving this problem is to develop wind power storage technology. When the wind-rich power grid is at a low peak, the excess power will be stored. When the power grid is at the peak of power consumption, the stored power will be input to the grid to ensure the stability of the grid-connected power. . Only by combining wind power technology and energy storage technology, complementing each other’s strengths, and complementing each other can the wind power industry develop smoothly.
Energy storage is to store temporarily unused energy and release it when it is ready to be used. It is divided into chemical energy storage, physical energy storage and other energy storage. Chemical energy storage mainly refers to the use of batteries to store energy; physical energy storage is divided into compression Air energy storage, pumped water energy storage, flywheel energy storage, etc.; other energy storage mainly includes superconducting magnetic energy storage, super capacitor energy storage, hydrogen storage energy storage, heat storage energy storage, cold storage energy storage, etc. The above-mentioned energy storage methods have their own merits. However, there is a lack of an energy storage method that is simple to use, large in energy storage, less investment and quick in effect, and economical and applicable. The birth of the patented technology of “a high-efficiency solid accumulator” may change this status quo.
