A new method for loss reduction based on simultaneous DG placement and network reconfiguration

Summary from only given. This Distributed generations (DGs) represent an efficient option for overcoming problems and challenges of power utilities like loss reduction, load growth, reliability improvement and green house gas effect reduction. Appropriate sitting and sizing of DGs play a remarkable role on loss reduction. In this paper a new effective method for DG allocation is proposed that has more ability for loss reduction during system operation. In this method reconfiguration as new subject has been added to former DG allocation algorithms, so different possible configurations are considered for DG placement problem. In the other words DG allocation and reconfiguration are done simultaneously. Also to overcoming time-consuming of reconfiguration TLL-based reconfiguration is presented in this paper. In this reconfiguration method a profitable solution for finding all possible loops is suggested, that is based on two TLL and CT/M matrices calculation. This proposed approach is applied to both test and real networks. All proposed procedures are programmed in DIgSILENT program using DPL. The Simulation results demonstrated the practical benefits of proposed approach.
