smart grid gotland

During the Almedalen week in Visby, Gotland Energi (GEAB) and sub project market test arranged a seminar where representatives from GEAB and the project discussed customer solutions that will enable the smart grid in Gotland. The 1200 volunteering test pilots were specially invited and they and the other visitors asked questions to GEAB and the project.

The event was visited by approximate 220 persons and on site to answer questions were Jenny Larsson from GEAB, Christina Svalstedt och Johan Söderbom from the project and Vattenfall and Lars Ejeklint, energy advisor at Vattenfall. (2013-09-04)

Swedish Utility Creating Smart Electricity Network

Ventyx is joining an initiative to create a smart electricity network, part of a development project entitled Smart Grid Gotland. As part of the project, Ventyx will deploy a comprehensive Distribution System Optimization solution encompassing network control, demand response management, demand forecasting and business analytics to support the project, enabling large quantities of wind and other renewable and distributed energy sources to be integrated into the grid, while maintaining reliability and providing better operational performance.

Ventyx is working with several partners on the project, including Gotlands Energi AB (GEAB), the utility serving the Swedish island of Gotland. GEAB is 75 percent owned by Vattenfall, one of Europe's largest generators of electricity, which is also a major partner in Smart Grid Gotland.

The project was initiated in response to the European Union's climate change target to reduce carbon emissions by 20 percent by 2020. Sweden plans to increase its renewable electricity production primarily through wind power, as generated on the Island of Gotland – the largest island in the Baltic Sea 90 km from the Swedish mainland – providing customers with low carbon, sustainable power supplies. After this Gotland pilot, the solutions and ideas could be transferred to larger-scale projects on the Swedish mainland and in other European countries, providing citizens with more reliable power and an opportunity to control their energy consumption and costs.

The distribution management system (DMS) software by Ventyx, integrated with ABB hardware, will be used to address bottlenecks in the distribution network that may restrict the flow from the wind turbines to consumers.

"Wind power is produced out in the distribution grid and, like solar energy, is highly variable, presenting challenges when it comes to power quality, surveillance and control of the grid," said Veijo Huusko, Head of R&D Portfolio Management, Vattenfall Nordic. "Using industry-leading network management software from Ventyx to create a more intelligent and efficient grid, we can increase the use of renewable energy sources, improve power quality and create added cost-savings for customers over conventional grid technology."

Ventyx Network Manager SCADA systems will cover one of the island's substations and its associated network – managing daily operations and helping to reduce the duration and frequency of outages through the use of smart meters and other equipment in the field. The Ventyx business analytics solution will analyze data from the SCADA/DMS/OMS system, and potentially other sources to help boost operational efficiency and reliability while reducing costs.

Smart Grid Gotland is a cooperation project between Vattenfall, ABB, GEAB, Svenska Kraftnat, Schneider Electric and KTH, and is partly financed by the Swedish Energy Agency. The project was begun in September 2012 and will run to December 2015 and has three overall objectives: 1) cost efficiently increase the hosting capacity for wind power in an existing distribution system; 2) show that novel technology can improve the power quality in a rural grid with large quantities of installed wind power; and 3) create possibilities for demand-side participation in the electricity market, in order to shift load from peak load hours to peak production hours.
