Grid stabilization for a sustainable and reliable energy supply
To increase the reliability of AC grids, improve power quality, and boost transmission efficiency, Siemens Energy successfully implements many and varied projects in transmission systems around the world using state-of-the-art Flexible AC Transmission Systems (FACTS).

STATCOM systems, for example, stabilize fluctuations by absorbing or feeding in voltage-supporting reactive power, depending on the requirements. Approximately two-thirds of the globally installed STATCOM systems with modular multilevel converter technology are from Siemens Energy. Based on the technology of conventional static var compensators, Siemens Energy has developed additional innovative solutions, such as the SVC PLUS FS frequency stabilizer and the mobile STATCOM, which stabilize the grid and close gaps in energy systems around the world.

In September 2020 Siemens Energy launched its newest grid stabilization solution: the Unified Power Flow Controller UPFC PLUS. It will help system operators stabilize the grid by dynamically controlling the load flow in alternating-current grids. Easy to integrate into existing infrastructure, the UPFC PLUS improves the efficiency of today’s power grid while providing the grid stability and resilience required in the ever-changing energy landscape.

Grid stabilization for a sustainable and reliable energy supply 

On the 29th September 2020, Amprion and Siemens Energy celebrated the commissioning of a new STATCOM (Static Synchronous Compensator) at the Kusenhorst substation in Haltern am See (Germany). Amprion is relying on an SVC PLUS system from Siemens Energy, an advanced STATCOM with which Amprion can adapt the voltage flexibly and quickly enough to ensure a stable power supply for the entire region.

Static var compensators help stabilize the grid

In Amprion's Kriftel substation, state-of-the-art static var compensators support the power supply for the industrial plant in Frankfurt. Amprion is once again relying on Siemens technology. The one-hundredth STATCOM system from the SVC PLUS series will be deployed in the important Kusenhorst node (Germany) to stabilize the grid.

Siemens developed the world's first mobile STATCOM

Mobile STATCOM gives the utility an unprecedented level of flexibility to move the device anywhere grid support is needed, especially in cases of unexpected outages from extreme weather or unplanned events.

The frequency stabilizer SVC PLUS FS supports power grids in milliseconds

With its SVC Plus Frequency Stabilizer (FS), Siemens is the world's first supplier to combine reactive power compensation capability with the use of so-called supercapacitors. The SVC Plus FS can feed the reactive power needed for stable grid operation in less than 50 milliseconds. At the same time, the up to 200 megawatts of electric power stored in the supercapacitors can be transferred to the grid at full load. As a result, the voltage and frequency, and thus also the grid, remain stable.
