At 10 times performance and 10% of the cost of Ripple Control, DigitalTF is a paradigm shift for LV grid congestion management. Independent from IoT and Internet providers, fully under control of the grid operators. No ICT personnel required for installation. 100km+ range without repeaters. All EV chargers and PV inverters automatically connected to the right distribution substation, without any programming. That is DigitalTF.
DigitalTF is a GridShield that delivers.
DigitalTF is low frequency powerline communication. A 21st century, high-performance, low-cost successor of Ripple Control. The transmitter is a small
DIN-rail mounted unit in the distribution substation. The coupler/injector a snap-on current transformer. Reception is software-only integrated into the firmware of EV chargers and PV inverters.
A DigitalTF telegram is 1 second short, has an amplitude of 0,4V and uses phase-synchronous subharmonic Manchester bit coding with FEC error detection/correction. DigitalTF telegrams repeat 24/7 and have a level of robustness that Ripple Control could only dream of.
After the switch from fossil fuel energy to sustainable energy sources, the Low Voltage grid can no longer function the way it does today. EV chargers need to be curtailed in the late afternoon and early evening. PV inverters require peak shaving on very sunny days. Home battery systems should be overruled in the case of grid overload.
The narrative over the last 20 years has been that IoT will couple all electric devices to a comprehensive management system. That is not materializing: Iot is vulnerable, complicated, hackable, short-term and expensive. It requires too much ICT personnel that simply isn't available.
