The optimal capacitor placement is defined by determination of the number, location, type and size of the capacitors installed in the radial distribution network. In such problem, different objective functions may be defined.

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.
