MVDC PLUS®

MVDC PLUS®

Product catalog summary
Overview: The document discusses Siemens Energy's MVDC PLUS® technology, which is designed to enhance the management of future electrical grids by integrating Direct Current (DC) advantages into Alternating Current (AC) grids.
Key Features:
  • Grid Connection: The technology allows for the connection of weak or unstable grids, enabling control of load flow and provision of reactive power.
  • Grid Decoupling: It facilitates the decoupling of grids regardless of frequency, voltage, and quality, thus bridging distances effectively.
  • Compact Installation: MVDC PLUS® supports the installation of compact, cost-efficient medium-voltage DC connections via cables or compact overhead lines (OHLs).
  • Environmental Impact: The system contributes to CO2 reduction by minimizing the need for diesel generators.
  • Power Infeed and Transfer: It increases power infeed and enables greater power transfer within existing infrastructures.
  • Grid Stability: The technology improves grid stability with STATCOM functionality.
  • Reduced Footprint: Medium Voltage (MV) level allows for lower lines below treetops and smaller corridors, using wood poles or simple structures.
  • Transmission Autonomy: It provides transmission autonomy in power ranges up to 150MW and establishes direct MVDC transmission links and additional grid nodes.
Context and Challenges: The document highlights the challenges posed by climate goals and the integration of volatile renewable energy sources, which require new approaches to manage existing infrastructures.
Technical Terms: The document includes abbreviations such as AC (Alternating Current), DC (Direct Current), MV (Medium Voltage), and OHL (Overheadline).
Conclusion: Siemens Energy's MVDC PLUS® offers a solution for integrating DC advantages into AC grids, facilitating improved load flow control and grid management.
