Abstract
A modular multiport converter system includes a plurality of distributed controllers, associated with different ports of the system that are able to synchronize to ensure that power drawn from the system is equal to power supplied to the system with precise timing. The distributed controllers are able to receive a clock signal from a leader controller, or from a vice leader controller in the event that leader controller is unable to function.
Claims20
A system for synchronizing multiple power sources and/or multiple demand loads, comprising:
- a central transformer connected to a plurality of ports;
- wherein each of the plurality of ports is galvanically isolated;
- one or more DC sources or loads connected to the central transformer via one or more DC bridges;
- one or more AC sources or loads connected to the central transformer via one or more AC bridges;
- and at least one master controller configured to generate a synchronization signal and transmit the synchronization signal to one or more distributed controllers;
- wherein the one or more distributed controllers are operable to determine minimum delay timing for each of the plurality of ports;
- wherein the at least one master controller is operable to communicate via interfaces compliant with the Institute of Electrical and Electronics Engineers (IEEE), International Electrotechnical Commission (IEC), American National Standards Institute (ANSI), and/or any other standard for grid interoperability and integration;
- and wherein the at least one controller includes one or more automated cybersecurity modules and/or one or more fault protection modules for detecting threats, isolating affected modules, and autonomous restoration of operations.
