The next generation of electric distribution automation

Connecting tomorrow's grid

Switched Source helps distribution system operators better utilize legacy grid infrastructure by providing power-electronics that increase reliability and efficiency, as well as increasing the system’s capacity for hosting renewable and distributed energy resources.
Switched Source’s flagship device, the Tie Controller, unlocks superior grid management capabilities, acting as a controllable valve to “push and pull” specified amounts of both real and reactive power bi-directionally.  As a result, neighboring power lines can be operated as a networked platform providing all energy consumers with two sources of power.
Increased Reliability

In the event of a fault, consumers that would normally be left without power for minutes to days while repair crews are dispatched, can immediately recover as the system borrows excess capacity from a separate line. As an added advantage, the Tie Controller can perform this service between lines which are otherwise incompatible due to voltage or phase-angle differences. 

Distributed Energy Resource (DER) Hosting

The Tie Controller provides a retrofit solution for legacy infrastructure to accept and fully utilize distributed energy resources. In domestic or foreign microgrid applications, the Tie Controller is an enabling tool for “plug and play” interconnectivity of assets and agile system management in a wide range of environments.

Non-Wires Alternatives (NWA)

The Tie Controller’s ability to effectively balance loads between neighboring circuit feeders and/or substations can eliminate undue stress and inefficiency caused by overloading and peak load pockets. Imagine the savings installing the Tie Controller in these problem areas will generate as you reduce the need to overbuild entire segments of the distribution system, which is especially valuable in urban and hard-to-permit areas

Emergency Response

With the increasing severity of natural disasters comes a growing need for rapid system recovery.  At just 20% the weight of a similarly sized transformer and requiring virtually no customization, the Tie Controller offers a mobile solution to quickly couple an entire circuit feeder (up to 10 MVA) directly to a genset installation.
