Grid Stabilization with Variable Shunt Reactors

Variable shunt reactor technology reduces investment cost and boosts efficiency for stable power supply

1 min read


Flexible and economic grid even in times of changing energy landscape: With the growing extension of renewable power generation comes the challenge of keeping grids stable. The need for reactive power compensation equipment is increasing; and at the same time these assets need to become more flexible because the infeed from renewables is volatile.

A cost efficient and flexible solution is the combination of shunt reactor technology with on-load tap-changers as used in power transformers for decades already. Grid operators benefit from improved voltage control and reduced reactive power loading of the grid.  These two benefits reduce losses in the lines, connected equipment, and the variable shunt reactor itself compared to a fixed shunt reactor.

Join our webinar on September 27th to learn more about reactive power compensation and typical applications, differences between fixed and variable shunt reactors as well as technical aspects of variable shunt reactors and the on-load tap changer. A special focus during this webinar is on a typical business case to demonstrate the economic side of the topic.

The Dutch city of Utrecht is embracing vehicle-to-grid technology, an example of which is shown here—an EV connected to a bidirectional charger. The historic Rijn en Zon windmill provides a fitting background for this scene.

We Drive Solar

Hundreds of charging stations for electric vehicles dot Utrecht’s urban landscape in the Netherlands like little electric mushrooms. Unlike those you may have grown accustomed to seeing, many of these stations don’t just charge electric cars—they can also send power from vehicle batteries to the local utility grid for use by homes and businesses.

Debates over the feasibility and value of such vehicle-to-grid technology go back decades. Those arguments are not yet settled. But big automakers like Volkswagen, Nissan, and Hyundai have moved to produce the kinds of cars that can use such bidirectional chargers—alongside similar vehicle-to-home technology, whereby your car can power your house, say, during a blackout, as promoted by Ford with its new F-150 Lightning. Given the rapid uptake of electric vehicles, many people are thinking hard about how to make the best use of all that rolling battery power.
