As mentioned earlier, since energy conversion and storage devices work on different physical or chemical mechanisms, it is difficult to integrate two completely different units. Because, the research of a highly integrated all-in-one power system is not accomplished overnight, but after a long period of active exploration and hard research.
From 2007 to 2016, for example, total installed wind power capacity quintupled from 95 gigawatts to 487 gigawatts worldwide. China and the United States possessed the greatest amount of installed wind capacity in 2021 (with nearly 329 gigawatts and almost 133 gigawatts, respectively), and that same year Denmark …
