There must always produce the same amount of power used. Today is the only power producers and a few large industrial customers who contributes flexibility power consumption is very high, or when network failures or power plants threaten the power supply.
But now tests Statnett new technology and consumption management also with smaller customers. The use of smart electricity meters will Statnett namely strained periods distribute available power for real needs, and thus could prevent the widespread power outages.
The testing takes place in Lofoten / Vesterålen / Harstad neighborhood cooperation with Lofotkraft, Trollfjord Kraft, Halogaland Kraft and Vesterålskraft, because this area has been plagued by failures and blackouts in recent years.

Customers notice little
The project was started a year ago.
Statnett and the underlying network operators in regional and distribution During the years developed functionality in processing facilities, and secure data communication between themselves and out of smart meters to customers who participate in the project were installed.
27 customers with the AMS-switching part of the project. Both public buildings, industrial and commercial buildings were, but no single households. Together they had an installed capacity of just over 20 MW.
The actual testing was conducted last week by Statnett disengaged consumption from their region in central Alta. At most, up to 5 MW was switched off.
The equipment was installed did that Statnett could disable only part of customers’ energy consumption, so that they will not notice it as much. Electric boilers, parts of ventilation systems and district heating systems are examples of plants that were switched off.

Successful test
Test logs will be analyzed to come, and the final report will not be ready until next year. But the results so far show that it is fully technically possible to control the consumption load in this way.
– It looks very positive. On our regional center in Alta had the full list of available cargo that was ready to be switched off. Switching worked mostly on all load objects. There was some debris in a few places, but the main block went as planned, says head of Statnett’s smart grid program, Stig Lövlund, to TU.
It took less than a minute before switching off the load among several Web companies’ customers had measurable power in the power system. Real-time monitoring of actual available flexible cargo is a new functionality in the operating system for both Statnett and regional utilities.
-The targeted disconnection here we have tested, gives us new tools compared to what we had previously . Instead darken an area to salvage as much as we can of the system, we here “gray out” an area using flexible spending loads and thus reduce the impact on the area, says Lövlund.

large scale
If the results prove to be as good as it may seem, looking Statnett for that technology in a few years will be used on a large scale.
– Do you see that Statnett should get the role to manage such a market for disconnection of power?
– AMS to be rolled out by 2019, and our motive is to investigate this further. The first step is to test a technical solution which demonstrates that this is actually possible to do. We have a lot to learn about how loads behave, both when connecting and out. Heat, for example, might get higher load when connecting in than out. It is also important that in future operate the system based on market solutions. It is a big job that we have not begun to look at, say Lövlund.
– You governs the already more markets for balancing power, then you may well also control this?
– It is important to first test the technology before we begin to think about solutions for market design. It is not long until 2019, and it is important that Statnett is to set some standards for how this is used.
The customers will be compensated
Lövlund want an interaction between Statnett and the underlying network operators.
– But Statnett must surely be able to override them in the use of lastutkoblingen?
– Statnett wants thorough dialogue with stakeholders, and it must be clear rules for who is using loads that can be disabled, so you do not sell the skin several times, says Lövlund.
In order to get customers on the load shedding in the future, they must according Lövlund achieve a gain of to be with. Moreover, he believes it should be simple and non-bureaucratic joining the scheme.
