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), balances the charging status of battery banks, and allows for control implementation without knowledge of the electrical grid's parameters and topology. Additionally, the technology can handle arbitrary connections of inverters within the microgrid, offering various advantages in the development of microgrids.
The patent claims detail the steps involved in the control process for single-controllable low voltage microgrids, the components required for implementing the process, and the technical elements involved in the operation of the microgrid. The microgrid is controlled by a central controller that facilitates the sharing of power between DERs, controls power exchange with the main grid, and manages the transition between islanded and grid-connected modes. The implementation includes various technical elements such as programmable sources, inverters, battery banks, and communication interfaces, all coordinated through a central controller and a specific algorithm. The patent also covers the use of this control process for single-controllable low voltage microgrids, emphasizing its application in controlling and managing the operation of such microgrids effectively.
