A Linearized Multiobjective Energy Management Framework for Reconfigurable Smart Distribution Systems Considering BESSs

This article investigates the impact of battery energy storage systems (BESSs) on the distribution system energy management (DSEM). The article introduces a linearized multiobjective DSEM framework for reconfigurable smart distribution systems (DSs) in the presence of renewable distributed generators (DGs) and BESSs. The proposed framework aims to achieve three objectives: minimizing the operating cost, minimizing the energy losses, and improving the voltage profiles. The proposed framework determines the optimal operational schedules for the network reconfiguration, the charging/discharging of BESSs, and the dispatch of the energy resources. The proposed DSEM framework is tested on two smart DSs that include BESSs and different types of energy resources. A comparison of the results obtained from different operational scenarios demonstrates the effectiveness of the proposed DSEM framework. The developed framework with BESSs has successfully achieved significant benefits: saving in the DS operating cost, reduction in the DS energy losses, and improvement in the DS voltage profiles.
