Abstract: This paper presents a summary of the power quality related concerns associated with the application of electric utility distribution system capacitor banks. These concerns include distribution capacitor switching transients and power system harmonics.
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.
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.
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.
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.
One of the other important advantages of capacitor placement in distribution network is to free up the capacity of feeders and related equipment, delaying or eliminating investment costs for improving or developing the system, and to free up the distribution transformers capacity.
