Distribution Transformer Tap Setting Control using Particle Swarm Optimization

Load uncertainty increases with the increase in power consumption, and it causes power losses, and low voltage profile in the radial distribution system. Improvement of voltage profile helps to reduce the power losses, DG and capacitor placement boost up the voltage at the consumer end. By the increase of distribution transformer tap settings the voltage profile of buses will be improved and reduces the power losses in the distribution system. But execs of voltage levels are causes higher power losses in the distribution system. This paper aims to reduce the real and reactive power losses in the distribution system by changing the transformer tap settings using the PSO algorithm. The proposed methodology examined on standard 15 bus distribution system with an EV charging station and DG system. Voltage-dependent load modeling is applied to a standard 15 bus test system.
