Two new mathematical models for two level electricity network design with distributed generation

In the new millennium, traditional electrical power systems have undergone a significant change driven by set of requirements arising from evolving and changing technology. Thus, fundamental changes occurred in way energy is produced, transmitted, distributed. This situation has revealed need to expand existing networks or establish networks. The available literature that particular attention latter one still limited due complexity system. purpose this study contribute body tries address gap at overall design distribution network. Moreover, distributed generation integration also considered simultaneously with network design. paper, two-level electricity system (TLEDS_DG) for green-field planning considered. TLEDS_DG defined find locations transformers, decide number generators, underlying such demand capacity constraints are satisfied, cost minimized. Two mathematical models, node-based flow-based, proposed compared terms solution quality CPU times. Within flow-based formulation which technique, called node cloning, used transform into single-level one. To validate effectiveness efficiency approach (flow-based cloning), we conduct numerical studies based on randomly generated instances up 300 customers. Additionally, sensitivity analysis applied demonstrate impacts initial parameter settings. Computational results large suite test problems show cloning) efficient highly effective problems.
