Voltage Control by Optimized Participation of Reactive Power Compensation Using Fixed Capacitor and STATCOM
It has already been discussed that cost of fixed capacitor is very low compare to STATCOM but fixed capacitors do not respond for system under dynamics conditions. STATCOM alone can provide an adequate solution of reactive power compensation for system voltage control but it makes system very costly.

B8: Capacitors, Dielectrics, and Energy in Capacitors
Similarly, a lower case (v) represents the variable amount of voltage across the capacitor (it too increases as we charge the capacitor), and the upper case (V) represents the final voltage across the capacitor.
The small black circles represent the location of the nuclei of atoms in the crystals, and the gray circles represent the electron cloud surrounding the nuclei of each atom. If an electric field is applied in the (hat{a}_z) direction, the material polarizes, so the electrons are slightly displaced with respect to the nuclei as shown in the figure on the right.
