The DC network offers higher efficiency and reliability over AC networks along with a simple control interface for electronic loads, renewable energy sources and hybrid energy storage (HESS) [1]. Moreover, modern loads in industry and residential systems are powered by DC sources making them ideal components of DC sub-grids [2] .
Capacitance. Any two electrical conductors separated by an insulating medium possess the characteristic called capacitance: the ability to store energy in the form of an electric field created by a voltage between those two conductors. Capacitance is symbolized by the capital letter C and is measured in the unit of the Farad (F).

The expression in Equation 8.4.2 8.4.2 for the energy stored in a parallel-plate capacitor is generally valid for all types of capacitors. To see this, consider any uncharged capacitor (not necessarily a parallel-plate type). At some instant, we connect it across a battery, giving it a potential difference V = q/C V = q / C between its plates.
