Abstract

This loss can be reduced by the use of a capacitor in the system, which injects reactive current and also improves the voltage magnitude in the buses. Shunt capacitors are commonly used in distribution system for reactive power compensation. The real power loss in the distribution line is the R.I2 loss which depends on the current and resistance. The radial distribution system is a rugged system, it is also the most commonly used system, which suffers by loss and low voltage at the end bus. In this paper, the optimal location and size of the capacitor is found using a new computational intelligent algorithm called Imperialism Competitive Algorithm (ICA). To calculate the power flow and losses in the system, novel data structure load flow is introduced. The proposed approach is examined and tested on 69 bus power network simulation results are presented and discussed.
