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.
In the method, the high-potential buses are identified using the sequential power loss index, and the PSO algorithm is used to find the optimal size and location of capacitors, and the authors in have developed enhanced particle swarm optimization (EPSO) for the optimal placement of capacitors to reduce loss in the distribution system.
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.
The results show that the approach works better in minimizing the operating costs and enhancing the voltage profile by lowering the power loss. Hybrid optimization of particle swarm (PSO) and sequential power loss index (SPLI) has been used to optimal capacitor allocation in radial distribution networks for annual cost reduction .
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.
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.
