2. Electrical microgrid design

In the remainder of this article, we'll deal only with the case of microgrids, i.e. those designed to ensure autonomy solely in terms of the electrical vector. These microgrids can be distinguished by :

• their level of autonomy. They can be "isolated", meaning they are not connected to any other network. In this case, they are totally autonomous, and cannot rely on any other network for backup. Otherwise, they are said to be "connected", i.e. they are connected to one or more external networks. The degree of self-sufficiency varies, and is characterized in particular by self-consumption and self-sufficiency rates;

• the type of current used in the microgrid. This can be either direct current ("DC") or alternating current ("AC"). AC microgrids are still the most common today, although the use of DC microgrids...
