Situation-aware Power Electronics in Resilient Distribution Systems with Reconfigurable Cyber-Physical Networks

Modern power grids operate as reconfigurable cyber-physical systems (CPSs), which result in improved system resiliency but also complex operation status. Distributed generators (DGs) could identify system behavior by implementing situation awareness (SA) functionality and in turn provide flexible and autonomous responses to the system events. In this work, a control framework is developed for inverter interfaced DGs operation in distribution systems with reconfigurable cyber-physical networks. The DGs understudy are assumed to be equipped with SA capability. The DG operation modes in response to the system’s major events/states are defined, and the transitions between each mode are linked using formulated situation parameters. A set of distributed controllers are designed for DG operation under each mode. The proposed control framework along with the distributed controller designs have been validated by performing a requested network reconfiguration on a 12-bus test feeder using MATLAB/Simulink.
