A distributed command governor method for the voltage control in smart grids with distributed generation and storage

Distributed Generation (DG) has gained relevance In Medium Voltage (MV)/Low Voltage (LV) power grids worldwide. One of the main drawbacks related to high penetration of DG plants is represented by abrupt voltage raises. Such an issue typically occurs in the presence of either low demand conditions or high power production from renewable sources. This work is focused on the online management of distributed generators and storage devices and exploits ideas of the Distributed Command Governor (DCG) approach, which is mainly based on the resolution at each time instant of an optimization problem minimizing management costs and containing explicit constraints on voltage bounds and operational ranges of relevant grid devices.
