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.
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.
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.
Optimal capacitor placement in distribution systems using a hybrid technique utilizing fuzzy and GA is suggested in to minimize the operating cost and the deviation of bus voltage and maximize the margin loading of feeders.
Using capacitors has positive effects on networks such as power and energy loss reduction, voltage deviation and network harmonic reduction as well as improvement in network power factor. Capacitor placement is applied on the network in a form of single or multi-objective problems.
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.
