Electrical currents – seeing Spain and Portugal on Monday – can be caused by a number of reasons, but this event highlights the “weakness” of the Iberian Peninsula.

Why is the reason not yet determined?

Electrical network is a complex system of materials connected to thousands of each other.

“Network operators need to carefully analyze large amounts of data”, frequency changes, lines dysfunction and power plants condition to track the sequence of events. “

What are the common causes?

Due to the technical problem, electrical cuts are often caused by the lack of fuel to stop the product source (power station) or supply thermal power plants.

In recent years, natural disasters – hurricanes, earthquakes, forest fires, heat or extreme colds have sometimes worsened due to climate change – destroying infrastructure or increasing demand for heating and cooling.

Other causes of high loads on high tension lines, which lead to transmission of extra electricity to other lines, and at this stage, at this stage, it is possible to be excluded in Spain and Portugal, but it is a growing threat due to increasing computerized networks.

Imbalance between supply and demand?

In Spain, the power company reported Monday evening, “strong fluctuations in energy currents, lost a very large product.”

The electric frequency is measured at the network in Europe as per the 50 Hz standard. Any frequency of this level does not produce enough electricity compared to the frequency reunion, but if this level exceeds, there is a need to produce less current. Operators are the job of ordering power plants in real time to maintain the frequency of 50 Hertz, to increase the product depending on the demand.

“This frequency is the balance of balance to preserve the frequency regeneration.”

If the frequency deviation from 50 Hz is carried out, automatic protection systems are maintained to turn off the parts of the network and damage the equipment.

“After the power plants begin to work to protect himself, the situation can get out of control quickly,” Hogan explained. But it is very rare to reach the stage we see »Monday.

But how did everything start?

According to experts, it is very difficult to give a definite answer: “There is a weakness of relationships between the peninsula and the rest of the western European network in the most likely contributing factors.”

According to Hogan it is a worker and not the main cause, “The cause may be one or two major transport facilities; it extends to other parts connected to the network, but the cause of this first failure is still determined.”

What is the effect of reproductive forces?

Spain produces 40 percent of the power of solar energy and wind energy. By noon, this percentage had reached 70 percent.

However, unlike the gas stations, the company reported “Restad Energy”, “It takes a few minutes to start operating”, “sun and wind power, and often decrease.”

In Europe (April 18), the body, which connects the operators of electricity systems, has warned of the dangers of solar energy as summer.

According to the “Restad” company, two power outages are “alert” position; “Without strong flexibility at the national level and without good regional coordination, future network interruptions may have more dangerous consequences.”

“Without adequate elasticity measures such as storage, fast operating stations and strong connection, great fluctuations in renewable energy production can lead to destabilize the network,” said Pratka Ramdas.

The consultant and energy policy professor at the “Herti” college in Berlin, Leon Herth, “It is” a system that does not rely heavily on the generation of traditional energy (nuclear energy, gas, coal, electrical power …). “
