Energiespeicher-Reverse-Power-Gerät

Ein mobiler Energiespeicher ist in der Regel kompakter als ein stationärer Solar-Energiespeicher. Er kommt als Ladestation für E-Bikes, E-Roller oder E-Autos zum Einsatz, leistet aber auch auf Baustellen, bei Veranstaltungen oder beim Camping gute Dienste. um damit zum Beispiel den Kühlschrank oder das TV-Gerät zu betreiben oder Wasser

How does reversible power-to-gas work?

Reversible Power-to-Gas systems can convert electricity to hydrogen at times of ample and inexpensive power supply and operate in reverse to deliver electricity during times when power is relatively scarce.

What is reverse power (RP) protection?

The purpose of the reverse power (RP) protection is essentially to prevent severe damage to the generator prime mover. For this aim, directional relays are usually utilised. RP condition (RPC) leads to initial oscillations of power and frequency which might exceed the RP threshold and lead to mal-operation of the relay.

What is a reverse power relay (RPR)?

For this purpose, reverse power relays (RPR) are utilised . The directional power relays are sensitive to loss of mechanical input power. When the mechanical torque of the prime mover falls, generator starts to work as a synchronous compensator, absorbing necessary active power (P) from the network .

Why is reverse power protection important for a generator prime mover?

It is noteworthy that, faster operation of this relay can effectively decrease the motoring time of the generator, mechanical stress on the turbine and compressor shaft and consequently the potential risks to the prime mover. The purpose of the reverse power (RP) protection is essentially to prevent severe damage to the generator prime mover.

What are reversible PTG systems?

By taking advantage of fluctuations in hourly electricity prices, reversible PtG systems not only act as buffers in electricity markets, they also broaden the supply sources for hydrogen as an industrial input and general energy carrier.

Will a renewable power source reduce reversible PTG break-even values?

It remains to be seen to what extent the addition of a renewable power source would improve the capacity utilization of a reversible PtG system and, therefore, lower the corresponding break-even values.
