  • Publication number: 20240405547
    Abstract: A control process for microgrids for voltage regulation on the main bus and power factor (PF) regulation at generator terminals is presented, especially in events scheduled in the microgrid that result in electrical transients, such as direct starting of induction motors (IM). The technology takes advantage of idle capacity of distributed converters (for example: frequency inverters, “variable frequency drive” or VFD) of microgrids making them, in coordinated manner, injecting and/or absorbing reactive power, in addition to exploit the reduced latency of autonomous VFD control during the transient. The Power-Based Control (PBC) technique is used and a modified Volt-VAr function is created applied during the transitional regime.

  • Publication number: 20240204531
    Abstract: This technology refers to a control process for single-controllable low-voltage microgrids (Mgs) (SCM) having centralized communication. The process is based on the “Power-Based Control” (PBC) technique by adapting it to the context of SCMs through a modified PBC process (MPBC). The technology includes a process that provides the following technical effects: (1) sharing of active power and reactive power proportionately to the capacity of distributed energy resources (DERs or DGs) in the MG, for example, rendering the use of batteries based on different technologies (lead-acid, ion-lithium, etc.) compatible; (2) compensation for the current unbalance at the point of common coupling (PAC); (3) allows exploration of battery banks by balancing the charging status of storage elements; (4) allows implementation of the control process without knowing the electrical grid's parameters and topology; (5) is able to deal with the arbitrary connection of inverters into the MG, in addition to other advantages.

  • Publication number: 20240120746
    Abstract: 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.

  • Publication number: 20230291229
    Abstract: This technology refers to a control process for low voltage microgrids with distributed communication, the process is based on two techniques: “Power-Based Control” (PBC) and “consensus protocol” (CP). The proposed technology resorts to PBC and CP techniques to take advantage of the combination of their technical features, achieving a low implementation complexity and concomitantly providing the following technical effects: 1) precise sharing of active power and reactive power proportionally to the capacity of distributed generators (GDs) at the MR; 2) control of the flow of active power and reactive power between the different phases of the MRs; 3) Current unbalance compensation at the point of common coupling (PAC); in addition to other advantages. The technology is applied in the technical field of equipment and infrastructure for microgrids (MRs) of distributed generators (GDs).
