Analyses of Smart Grid technologies and solutions from a system perspective

This paper consolidates the data, analysis and observations from a case study conducted in cooperation with the Smart Grid Gotland project. The analysis identifies how electrical power consumption interacts with distributed electricity generation such as wind and solar power and presents how it correlates to weather data and smart grid solutions. The analysis model developed based on the Gotland network is generic and hence can be functional in investigating other power networks of different size, voltage level and structures. The key observations from the study of smart grid solutions such as dynamic load capacity and energy storage solutions are specified. Based on the project, an overview of future risks and opportunities of smart grid systems is presented.
