> At that time the price of electricity on the official market was in the negative at around -1€/MWh.
> Current evidence therefore points to a problem in the synchronisation of the grid. All sources feeding power into the grid must be synchronised at the same frequency, 50 Hertz. To facilitate this synchronisation, stable base-load power is required, which is normally provided by nuclear and other large gas and hydroelectric facilities. These sources act as a natural buffer against disturbances
So:
- price is negative, so solar automatically disconnects not to pay for providing electricity
- nuclear is overloaded at unexpected time, it also disconnect due to safety.
Seems like a bug in accounting software for solar power plants. It disconnected too many power plants too quickly! I bet like 40% of solar plants are using the same software for managing connectivity.
