Greek authorities are worried Prolonged blackout in Portugal and Spain. I still know Investigate the exact causesBut there are indications that the Energy produced by renewable sources It may have caused the destabilization and any collapse of the distribution system in the Iberian peninsula.
Vassilis Ziogas, director of operations and control of the independent operator of the Greek electricity transmission system, explains to “Euronews” that thereThe management of renewable energies is a challenge Also for Greece and requires the cooperation of regulators, producers and the Ministry of Energy.
“In general, accidents of this type can occur in the networks,” he explains. “We, for our part, that we are responsible for their operation, we are taking measures to deal with them. In the first place, we are strengthen the network and increase maintenance. We are improving the network, we are developing it and this means that it is becoming resistant, we are increasing resilience. “
Account that also intervene in Production control: “Today the penetration of renewable energies is very typical. This particular production, the green energy, This is very useful and very cheap and that we all want because it does not contamine, Has particular characteristics. We must respect these characteristics, identify them and act according to them. “
“I will quote Holy Week as an example, but also the days in which we live: the Ministry, the regulatory authority, the operators, the United States and the Deddie (the operator of the Greek electricity distribution system) and the producers are working together. We are in permanent contact by exchanging orders and giving indications and measures have been taken which in the end seems to cut, but they are a necessity. An uncontrolled quantity, if we let it produce too much, run the risk of unbalanced the system. “
Could this imbalance cause a blackout?
The expert confirms that the imbalance, if it swells, can also cause blackout phenomena: “This is what we try to limit. It is always a risk that we will face when there are new energy sources”.
In the Admie Energy Control Center (independent electrical transport operator) the production and demand for energy are balanced daily. At the same time, a system of Waxing which allows the network operator to identify and face the computer attack threats.
The increase in renewable energy penetration e Limited connection with neighboring countriesThese are some of the factors that are believed to have played an important role in the great blackout of Spain and Portugal, they are also elements of the Greek energy network.
Therefore, in recent years, the Hellenic authorities have Intensified your efforts to interconnect Greece With neighboring countries, not only from Europe, but also with the Middle East, in order to provide maximum energy safety to the country.
