1. The rapid development of wind power photovoltaic industry will promote the development of large-capacity energy storage industry. Energy storage technology solves the problems of randomness and volatility of new energy power generation to a large extent, can achieve smooth output of new energy power generation, and can effectively adjust the changes in grid voltage, frequency and phase caused by new energy power generation, so that large-scale Wind and photovoltaic power generation can be easily and reliably integrated into the conventional grid. The future of energy storage batteries should be in the wind power and photovoltaic industries, especially the wind power industry that has already been deployed in large numbers. Wind resources are unstable. In addition, the second half of the night when wind resources are relatively large is also a low point in electricity consumption. Therefore, although the wind and photovoltaic industries have developed rapidly in recent years, they have been plagued by the word "connection to the grid". Energy storage technology applications that can help wind farm output smooth and 'peak-to-valley'.
