Multiterminal HVDC PLUS® systems build upon point-to-point concepts by incorporating more than two converter stations in a single integrated HVDC system with multiple converter stations and multiple DC transmission lines.
This enables more flexible and more complex power transmission opportunities such as collecting power from multiple generation sites (e.g., offshore wind farms, remote renewable energy sources) and distributing it across various load centers efficiently through strategic routing decisions made possible by advanced control systems inherent within specific and custom tailor-made multiterminal HVDC designs.
These set-ups enable increased flexibility in integrating multiple renewable sources into a single integrated HVDC system enhancing grid efficiency and footprint. It allows for dynamic rerouting of energy based on generation and/or demand fluctuations ensuring optimal utilization of power resources available across regions.
A key component which facilitates these advanced capabilities of multiterminal HVDC systems is the converter technology used – specifically, half-bridge and full-bridge converters. Each offers unique advantages and characteristics suited to different operational / performance requirements.
Siemens Energy vast experience from 15 successfully executed point-to-point HVDC systems showcases the reliability and capability of Siemens Energy as a most reliable and most trusted partner in the industry making complex multiterminal HVDC systems a reality.
Siemens Energy leverages decades of HVDC expertise & modular multilevel converter technology to its fullest capabilities, applying half-bridge as well as full-bridge converters. If required parallel converters can be used for increased power transmission capabilities and provide superior redundancy and unmatched flexibility.
