Application: Single-controllable low voltage microgrid, control process and use (Patent ID: US20240204531A1)
The technology developed by Petroleo Brasileiro SA involves a control process for single-controllable low-voltage microgrids (SCM) with centralized communication, utilizing a modified Power-Based Control (PBC) technique. This process enables proportional sharing of active and reactive power based on the capacity of distributed energy resources (DERs or DGs) in the microgrid, compensates for current unbalance at the point of common coupling (PAC), facilitates exploration of battery banks, and allows implementation without knowledge of the electrical grid's parameters or topology. Additionally, the technology can handle arbitrary connections of inverters and offers various advantages for the development of microgrids in the equipment and infrastructure sector.
The patent claims detail the steps involved in the control process for single-controllable low voltage microgrids, the components required for the microgrid system, and the implementation of the technology through technical elements like programmable sources, inverters, battery banks, and a central controller. The use of the control process is specified for controlling single-controllable low voltage microgrids, emphasizing the application of the technology in different configurations of microgrid systems. Overall, the technology and its associated claims provide a comprehensive framework for effectively managing single-controllable low voltage microgrids with centralized communication, offering benefits such as improved power sharing, current balance compensation, and flexibility in system configuration.
