Energy Optimization using a Self-Healing Method based on Multi-SOP Coordination in Active Distribution Networks

The main task of a networkconnected SOP is to improve power quality in an active distribution network. In the references, two control modes are created for SOP operation using backtoback voltage source converters. Using these two modes depends on the distribution network conditions in which the SOP is located. The first is power control, which is provided by independent control of real and reactive power. The second mode is source restoration which with a voltage controller makes it possible to feed isolated loads due to network faults. In this research, an optimal method is presented based on the several SOPs’ performance for active distribution networks and with the help of it, it is presented using selfhealing capability based on energy optimization that is presented. Compared to conventional switches, the coordination of multiple SOPs can provide voltage support and effectively increase the source restoration range to improve the load restoration level.  Surveys and simulations in the standard IEEE 33bus network in various scenarios show that with a combination of network reconfiguration and SOPs, loads in the power outage area are fully restored, which effectively improves the flexibility of distribution networks
