• Cost efficiently increase the hosting capacity for wind power
• Improvement of the power quality
• Enable demand side participation in the electricity market
Smart Grid Gotland - objectives
• Subprojects within R&D-activities are responsible for the overall project objectives
• Research Platform subprojects are responsible for the physical installations in the grid that constitutes the actual research platform
• Smart Substations and Rural Grid as well as Energy Storage have installations in Smart Grid Gotland Part-2
• In communication outside the project, subprojects Market Test and Market Installations are presented together as Smart Kund Gotland (Smart Customer Gotland)

Smart Grid Gotland – current situation
System services from wind power• Study how and to which extent wind power
can produce necessary inertia in the system, in order to maintain frequency and voltage levels
Automatic curtailment during critical load situations
• Create a just and efficient way to curtail wind power, which is accepted by a lage diversity of owners and communication solutions.

Improvement of the power qualitySurveillance on low voltage network
• The low voltage grid is surveyed by customers own meters which traditionally only been used for billing
• The condition of the network is surveyed in real time and disturbances is visualized in the operations centre
• Individual, relevant and understandable outage alerts, based on the information from customers own meter, should be issued automatically
