Real power loss reduction in distribution network through Distributed Generation integration by implementing SPSO

摘要

Renewable sources based Distributed Generation (DG) are placed in the vicinity of either customers or the load centers with the intention of minimization of the network power losses, improve voltage profile and recover substation capacity delivery. Thus, while placing DG units caution has to be taken so as to maximize the benefits. The current work presented in this paper describes several techniques to get optimal siting of DG units and their preliminary sizes to reduce power loss that enhance the reliability of power distribution system. Optimal sizing of DG is carried out using PSO and SPSO with arbitrarily generation of DG sizes. Here, objective function is taken to reduce the real losses of distribution network. An analysis of system operation has been done on IEEE-12 and 33 test systems and results obtained express the efficiency of proposed approaches. The distinct approaches have been implemented on standard networks in MATLAB®, in which SPSO diminishes real power losses up to 49.587 for 12-bus network while 48.09% for 33-bus network.
