The objective function of the capacitor optimal placement in distribution networks is the cost of installed capacitors, installation costs, etc., and the cost of power and energy losses. By minimizing the cost function along with the constraint, i.e., the permitted bus voltages and line currents, the optimal capacitor size and the location can ...
Shunt capacitor banks are widely utilised in distribution networks to reduce power loss, improve voltage profile, release feeder capacity, compensate reactive power and correct power factor. In order to acquire maximum benefits, capacitor placement should be optimally done in electrical distribution networks.

What is a Capacitor? A capacitor is a two-terminal passive electrical component that can store electrical energy in an electric field.This effect of a capacitor is known as capacitance. Whilst some capacitance may exists between any two electrical conductors in a circuit, capacitors are components designed to add capacitance to a circuit.
