Abstract:
This paper presents network reconfiguration of distribution system which is carried out by making changes in its topological structure with the help of switches. These switches were closed or opened such that the final network should be of radial network. The objective of feeder reconfiguration with Distributed generators is to obtain best arrangement of branches to be opened from every loop for optimum distribution network with least power loss and to enhance power supply reliability. It is used to compare losses with different reconfiguration and the one with least losses indicates optimal network and it also represents new algorithm such as heuristic method called ACOT to solve feeder reconfiguration problem. ACOT is a powerful swarm intelligence method for solving optimization problem which is inspired from natural action of ant colonies on how they discover food source and return to their nest by depositing pheromone and is able to find effective shortest way by the utilization of data collected in terms of deposition of pheromones on the edge of their path. Here the load flow is solved by forward and backward sweep method. ACOT uses switch transition, local/global updating rule to promote computation and algorithm involves selecting among possible configuration and identifying the one which has least power loss following a constraint. The above methodology is demonstrated utilizing test system of 33 buses. The simulation code is composed in MATLAB programming for analysis.
