Process for controlling low voltage microgrids

This technology is a process for controlling low voltage microgrids (MGs) with centralized communication, based on the “Power-Based Control” (PBC) technique adapting the same to a modified PBC (MPBC) process. The technology provides the following technical effects: 1) sharing of active power and reactive power proportionally to the capacity of distributed energy resources (DERs) of the MG; 2) power unbalance compensation at the point of common coupling (PCC or PAC in Portuguese); 3) the process can be implemented without knowing the parameters and topology of the power grid; 4) ability to handle the arbitrary connection of inverters in the MG; 5) it makes possible to distinguish between DERs connected to the MG in both types of connection: phase-phase and phase-neutral, wherein single-phase DERs connected arbitrarily between the phases share the amounts of balanced power, while the unbalanced and homopolar powers are steered only to the inverters connected between phase and neutral; 6) it allows the connection of the MG to multiple PCCs and also the operation in isolated mode (“islanded”). The technology is applied in the technical field of equipment and infrastructure for the development of MGs.
