Hitachi Energy has unveiled AxoniQ, a new portfolio of solutions designed to optimize multi-terminal direct current (MTDC) systems. As the demand for electricity grows globally, these systems are crucial for maintaining a secure, affordable, and sustainable power grid.
MTDC systems facilitate dynamic power flow between multiple terminals and across various energy markets, supporting the rapid deployment of renewable energy and improving grid resilience. By directing electricity to where it is most needed, these systems help manage congestion and enhance the efficiency of power distribution.
The European Network of Transmission System Operators for Electricity (ENTSO-E) has highlighted the necessity for significant transmission expansion and early hybrid grids in its Offshore Network Development Plans 2024 report. By 2040, Europe is expected to scale up offshore renewables, with MTDC systems projected to boost transmission capacity nearly threefold.
AxoniQ's portfolio includes AxoniQ Protect, which offers rapid fault interruption, AxoniQ Connect for modular DC switching, and AxoniQ Control for advanced grid management. These solutions enable real-time power rerouting, rapid fault isolation, and continuity of power supply, minimizing costly interruptions.
Niklas Persson, CEO of Hitachi Energy's Grid Integration Business Unit, stated that AxoniQ marks a milestone in the evolution of DC grids, facilitating the integration of renewable power more reliably and affordably while improving grid resilience and transmission efficiency.
AxoniQ is part of Hitachi Energy's Grid-enSure portfolio, aimed at stabilizing power systems by managing frequency variations and system voltage. The solutions have been developed over more than a decade to ensure interoperability and compatibility in future HVDC systems.
As governments and grid operators worldwide invest in transmission infrastructure, AxoniQ is positioned to support the transition to a fully electrified world, integrating renewable energy at scale and enhancing cross-border interconnections.
