An energy management system for a high-voltage direct current (HVDC) transmission network includes a HVDC transmission line with first and second ends and a corresponding HVDC voltage. A first modular multilevel converter (MMC) is linked to the first end, interfaced with a first AC grid via a point of common coupling (PCC) that maintains a specific voltage. At the opposite end, a second MMC with its own voltage rating is connected, which in turn links to a second AC grid. This grid integrates renewable energy sources, comprising solar photovoltaic and wind farm systems, along with a battery energy storage system that includes a battery governed by a dedicated controller. The second PCC voltage is managed within the second AC grid. The system permits the second MMC to regulate the overall HVDC voltage, ensuring efficient energy distribution within the transmission network.
An energy management system for a high-voltage direct current (HVDC) transmission network, comprising:
A method to control excess energy in an HVDC network, wherein the HVDC network comprises a HVDC transmission line having a first end, a second end, and a HVDC voltage, a first MMC having a first MMC voltage connected to the first end of the HVDC transmission line, a first AC grid having a first PCC connected to the first MMC, wherein the first PCC has a first PCC voltage, a second MMC configured to regulate the HVDC voltage and connected having a second MMC voltage to the second end of the HVDC transmission line, and a second AC grid having a second PCC connected to the second MMC, wherein the second AC grid comprising at least one solar photovoltaic system, at least one wind farm system, a battery energy storage system comprising a battery and a battery controller, and a second PCC having a second PCC voltage, comprising:
