Voltage Control in Distribution Networks in Presence of Distributed Generators Based on Local and Coordinated Control Structures

Nowadays, many factors lead to selection and utilization of distributed generations (DG) in distributed networks. But more penetration of DG's in network faced with problem due to existence of passive and inactive distribution networks. One of these essential issues is voltage rise due to injection of active power generated by DG's. That in this paper, control strategies for controlling of voltage profile of distribution network and adjustment of increase of DG's penetration is assessed and an optimal strategy for voltage rise with mathematical formulation is presented that will include both local and coordinated control approaches of reactive power generation. Finally, in this paper an implementation plan with smart control tools of DG's is suggested.
