A microgrid presents various types of generation sources that feed electricity, heating, and cooling to the user. These sources are divided into two major groups – thermal energy sources (e.g.,. natural gas or biogas generators or micro combined heat and power) and renewable generation sources (e.g. wind turbines and solar).
