**2.5 Diverse generations (DGs)**

A single source of electric power delivery to the consumer, local load is a diverse generation strategy such as conventional fossil fuel generation like oil, coal, etc. or renewable energy method such as solar, wind, hydro, biomass, geothermal, etc. Diesel or gasoline generators that are usually and commonly use in the rural areas are all categorized as small diverse electric generators' power sources. The diverse generator located by left of the figure and representing either of conventional or renewable energy diverse source according to this author [13]. The integration of diverse energy sources for the operation, control, power management in real time power system make up a micro grid or network as positioned by Ashourian et al. [14]. Obviously, micro grid has distribution structure like the macro grid except that it is a smaller size, in a tiny network, and has a low power capacity. Diverse generation is made into a hybrid design mix whenever the hybrid energy storage is integrated into the micro grid structure to reliably evacuate power to the load.
