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.
Therefore, the optimal locations and sizes of capacitors in distribution systems can be formulated as a constrained optimisation problem. To solve this problem, the optimisation techniques are applied. Many optimisation techniques were applied to solve the optimal capacitor placement problem.
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.
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.
To solve these problems with saving in energy, reduced in cost, increased in reliability and power quality, the shunt capacitors are installed on the radial feeders for reactive power injection. Therefore, the optimal locations and sizes of capacitors in distribution systems can be formulated as a constrained optimisation problem.
In most power applications, inductance prevails and reduces the amount of pay-load power produced by the utility company for a given size of generating equipment. The capacitor counteracts this loss of power and makes powerproduction more economical. Figure 2 – Pole-mounted capacitors. (a) Primary and (b) secondary
