MSFL based determination of optimal size and location of distributed generation in radial distribution system

摘要

Loss reduction is one of the prime objectives for distributed generation placement in distribution network. To maximize the DG benefits, optimal placement of each DG is most important as DG benefits are site and size specific. The aim of this work is to minimize the active power loss and to improve voltage profile of overall system by optimal sizing and sitting of multiple DGs. To find out the optimal size and site two different optimization techniques -namely Teaching-learning based optimization (TLBO) algorithm and Modified shuffled frog leaping algorithm (MSFL) are used. The method has been tested with IEEE standard 33-node radial distribution network and the results obtained by two different algorithms are compared with each other.
