What is the objective function of capacitor optimal placement in distribution networks?

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.

How shunt capacitors are used in distribution networks?

For compensating reactive power, shunt capacitors are often installed in electrical distribution networks. Consequently, in such systems, power loss reduces, voltage profile improves and feeder capacity releases. However, finding optimal size and location of capacitors in distribution networks is a complex combinatorial optimisation problem.

Why do we use capacitors in distribution networks?

Decreasing the total network loss is often the main reason for using capacitors in distribution networks. Capacitor placement approach involves the identification of location for capacitor placement and the size of the capacitor to be installed at the identified location.
