Mysterious frequency changes
An unexpected change in the power frequency in Sunday morning and evening, hours before Blackout in Spain and Portugalrecorded the operator of the British Energy System Operator, NESO. Keeping electricity in the appropriate ranges is crucial To maintain the power supply lighting. Neso is already analyzing this situation.
What happened in Great Britain?
The first event occurred at 2 am at the Keadby 2 gas power plant in Lincolnshire. After this event there was an unexplained failure of the Viking Link interconnector, i.e. high voltage cables that connect Great Britain and Denmark. The second event was around 6pm, but it is not known what the frequency changed. The Neso spokesman did not provide details, but informed that now There is no indication that these problems were related to the Blackouts in Spain and Portugal. Presumably, problems in Great Britain could result from failures on the Danes side.
It could have happened in Spain
The cause of Blackout could be indirectly that Spain is very much about sun and wind farms – Jordi Sevilla, former president of the Spanish power network operator Red Eléctrica, said on Tuesday in “Cinco Días”. Renewable energy sources They do not generate so -called inertia (system inertia), which helps stabilize the frequency of energy systems. And it creates – how I'm writing Sevilla – The obvious problems that politicians ignored. However, his opinion is not shared by Michael Hogan, a senior advisor in the organization regulators Assistance Program (rap). “Universal power outages, such as this, were practically always caused by transmission networks, and not by generating energy from renewable or other sources” – he explains in information press released to our editorial office
However, this is not renewable energy?
Experts, however, agree on the need to invest in the power network. According to Jordie Sevilla, power networks must be adapted to the technical realities of the new energy mix. In this matter, Szymon Kardaś from the Think Tank European Council of Foreign Affairs agrees with him: “Blackout in Spain and Portugal makes us aware that energy security is much more than stable supplies of fossil fuels and the diversification of their suppliers. It is also properly developed and maintained in good condition power networks and the level of integrating with other countries, especially through other states, especially through other states, especially through other states, especially through other countries, especially Appropriately developed power interconnectors between EU Member States. ”
