All researchers aspire to maximizing their readership. You are no exception: the more readers you have, the more your work will be cited, and the greater your academic visibility will be. The keywords section plays a fundamental role in ensuring that other researchers can find your work. To decide which words and phrases to include in this section, think about the main topics of your research and which terms you would type into a search box to find it. Include the following: words related to the main field of study, the most frequently used terms in your document, synonyms for some of the main concepts, acronyms, and any other term you feel may optimize a keyword search. Remember, though, that the function of keywords is to supplement the information given in the title, so try not to repeat any of the words from the title in the keywords section.

After your work has been published it may be sent to various databases where it will be indexed on the basis of the words in the keywords section, the title and the abstract. If these sections contain words and phrases that other researchers use to search the literature, then your work will appear towards the top of their search results.

So, for the keywords section of the abstract Deep Reinforcement Learning-Based Controller for SOC Management of Multi-Electrical Energy Storage System (see Abstract), any of the following terms could be suitable for inclusion.
