Abstract


Reconfiguration is the process of modifying the open/close status of the switches of distribution network for optimization. This paper presents a fast algorithm for reconfiguration under typical conditions of the distribution network. The proposed technique efficiently utilizes Plant Growth Simulation Algorithm (PGSA), which is specially suited to large-scale distribution systems. A well-designed method of the decision variables, which describes the radial feature of the distribution network and considerably reduces the dimension of the variables in the solved model, is developed. Furthermore, greedy algorithm one of the algorithm design technique has been incorporated with PGSA to speed up the process. The incorporation of Greedy algorithm with PGSA condenses the computation effort. The advantages of the proposed approach in relation to previously published algorithms are that the solution procedure is very simple, easy to adapt any kind of radial distribution network and unambiguous definitions on reconfiguration procedure.Software simulation has been done through servlet programming(Java 2 Enterprise Edition Programming) to decrease software couplings. The effectiveness of the proposed approach is demonstrated by employing the feeder switching operation to a 33-bus and 82-bus large-scale distribution networks.
