Coordinated Control of Single-Phase End-Users for Phase Load Balancing in Active Electric Distribution Networks

In the paper, a coordinated control methodology of single-phase (1-P) end-users switching operations on the phases of an active electric distribution network (AEDN) has been proposed to obtain a minimum unbalance degree at the coupling common point (CCP) level with the main distribution system. The...
