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.

Claims (29)

1 . 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.

2 . The system of claim 1 , wherein the one or more AC bridges include at least one or more back-to-back connected transistors and/or one or more monolithic bidirectional switches.

3 . The system of claim 1 , wherein the one or more DC bridges include at least one H bridge with inductive, capacitive or hybrid coupling to the central transformer.

4 . The system of claim 1 , wherein the at least one master controller and/or the one or more distributed controllers utilize phase-locked loops (PLLs) to synchronize the plurality of ports.

5 . The system of claim 1 , wherein the plurality of ports are operable to connect to at least one medium-voltage load and/or medium-voltage source.

6 . The system of claim 5 , wherein the at least one medium-voltage load and/or medium-voltage source is operable to comprise medium-voltage alternating current (MVAC) and/or medium-voltage direct current (MVDC).

7 . The system of claim 1 , wherein the system utilizes look-up tables (LUTs), adaptive predictive methods, AI-driven algorithms, machine learning, or hybrid predictive techniques to provide feed-forward control of the plurality of ports.

8 . The system of claim 1 , wherein the at least one master controller or the one or more distributed controllers are operable to connect or disconnect individual ports through the use of AC/DC contactors and/or vacuum circuit breakers on each of the plurality of ports.

9 . The system of claim 1 , wherein the system utilizes intelligent adaptive management techniques using predictive analytics, machine learning, and/or artificial intelligence (AI) algorithms to synchronize and optimize energy demand and supply.

10 . The system of claim 1 , wherein the system is operable to dynamically add or remove energy sources, storage devices, and/or loads without substantial redesign.

11 . A method for synchronizing multiple power sources and/or multiple demand loads, comprising: providing a power conversion system including: 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; at least one master controller; and one or more distributed controllers; the at least one master controller generating a synchronization signal and transmitting the synchronization signal to the one or more distributed controllers; the one or more distributed controllers determining minimum delay timing for each of the plurality of ports; utilizing look-up tables (LUTs), adaptive predictive methods, artificial intelligence (AI) algorithms, machine learning, or hybrid predictive techniques to provide feed-forward control of the plurality of ports; and 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.
