This work is a qualitative proposal of a new FACTS device, which aims to repower the "Smart Grids", to a higher level. The existing FACTS that are covering the role of power flow control have the disadvantages of the use of electronic devices, and generate excessive heat and harmonics injected into the network. These devices are expensive and their regulation is binary: zero flow or total flow. This proposal offers a more versatile power flow control from zero to one hundred percent of its nominal capacity. Smart grids will no longer need to have a Relay Counseling Center, and the communication by pilot wire or other means available will be enough to control and protect the network. Therefore, due to fewer crossed and analyzed data, the laborious task of considering whether an event is really a failure, will be less complicated and will be carried out more quickly.
In combination with phase measurement units (PMUs) for each MAG, approximation techniques will not be necessary to estimate the variations caused by the dynamics of the demand, because the MAG is operating in "floating mode" as discussed further below. The network automatically and gradually rearranges these variations. Incomplete observation could be used for measuring voltage and current signals of the network in some specific points in the network.
