IT and telecommunications
In 2015, IT and telecommunications continued to be a major factor in our activities and for the transmission system as a whole. We updated key systems, improved telecommunications, safety and security and brought new Energy Management System terminals into service.
Software system for the regulating power market
We started developing a new software system for the regulating power market during the year. The system will manage offers and bids and send control values to Landsnet’s Energy Management System to maintain balance in the electricity system. The project was tendered out in the European Economic Area and was won by the software company Kolibri. The aim is to bring the new system into service in the second half of 2016. Named Reskja, the new system will replace the “Regulation Display”, an important support system in Landsnet’s Control Centre.
We completed the implementation of the incident and disaster management system SAReye. This puts Landsnet in the ranks of the Civil Protection Department and the Icelandic Association for Search and Rescue (ICE-SAR), both of which use this system in their day-to-day activities. SAReye is a management system for all incidents in the electricity system’s operation and is accessible wherever there is internet access. Considerable adjustment work went into tailoring SAReye to Landsnet’s needs, with further development work scheduled for 2016 to further increase the usefulness of the Incident Management System for the company.
Classification system for operating disturbances
A new system for classifying the severity of operating disturbances in the electricity system was adopted during the year. The purpose of the system is to provide faster and more effective information delivery to customers, i.e. consumers and generators, not least when transmission constraints or curtailments are necessary following extensive power disturbances.
The classification system is based on definitions used by the European Network of Transmission System Operators (ENTSO-E) of the severity of disturbances, to which were added categories for circumstances specific to the Icelandic grid. The system was also adapted to other Icelandic response systems; for example, the severity level of disturbances in the electricity system are classified using the same colour codes as used by the Civil Protection Department: Green (0) means a minor incident, yellow (1) means a moderately serious incident, red (2) means a serious incident and black (3) means a very serious incident that can result in a total systemic collapse.
The development of the classification system began in late summer 2014 when it became clear that volcanic activity was likely in the northern Vatnajökull ice cap. The hope is that the system will improve disturbance management by Landsnet’s Control Centre and help co-ordinate the responses of different operators.
The POLG innovation project
In 2015, Landsnet became a sponsor of the innovation project Power On-Line Generator (POLG). The aim of POLG is to create an internationally marketable product that increases the operational security of transmission grids and distribution systems, simplifies surveillance and maintenance, increases employee safety and reduces the risk of personal injury.
Developed by the research and innovation company Laki ehf, which specialises in eco-friendly energy solutions, the central idea of POLG is to use the electromagnetic field surrounding transmission lines to generate electricity. It is a very eco-friendly solution and is planned to deliver enough power to operate any electronic equipment, such as communications or monitoring equipment.
Other software projects
Our previous outage scheduling system, Rof, was replaced by a new software solution named RoVi. The new system is used to manage all information relating to planned shutdowns for maintenance and works. A settlement system from the IT company CGI (previously Lettera) was upgraded during the year in co-operation with the reseller. A new employee travel system was also introduced at Landsnet. The settlement of business trips is now entered directly into the financial system.
Security and telecommunications
Landsnet places a major emphasis on ensuring the security of its software and IT systems, which play an ever more important role in the grid’s operational security. In 2015, we continued to implement the ISO 27001 information security standard and carried out the annual security audit of Landsnet’s operations.
Our Control Centre’s Wide Area Monitoring System (WAMS), named PhasorPoint, plays an ever more important role in the grid’s day-to-day management. The doubling of this system’s capability was completed during the year to enhance operational security. Work commenced to implement WAMS measurements and controls in the Reykjanes region. A separate WAMS was also installed for the Westfjord Power Company, which can now monitor measurements for the West Fjords,
Having previously used ISDN D-channels for telecommunications, our substations were transferred to 2 Mb leased lines connected to the system of the energy telecoms company Orkufjarskipti. These connections can be expanded to up to 24 Mb. Equipment can be installed to separate connections for office networks, the Control Centre’s WAMS and other operating units.
Landsnet’s Energy Management System
The scope of our Energy Management System (EMS) has been growing from year to year, with 2015 proving no exception in this respect. The EMS terminal units at the substations at Glerárskógar, Geiradalur, Laxárvatn, Hólar, Hryggstekkur and Sigalda were renewed. A new control system at Krafla was connected to the EMS and a new terminal unit was installed at Prestbakki. A possible upgrade of the EMS was also prepared.
