The goal was to understand, what should one consider due to increasing wind energy production and changes in electricity infrastructures. The goal was also to explain, what kind of phenomena, actors or constructs wind power systems hold inside them. \n\nTheoretical part assessed system theory, critical infrastructure and its complexity, resilience, and change. The theoretical part also described energy systems being a part of both complex adaptive systems and critical infrastructure. The research problem was approached with constructive method, trying to solve real life problems while also producing value to scientific community. As a result, solution models were presented. Research methods included expert interviews, a systematic literature review and scenario analyses. \n\nBased on the results, the possible disturbance in terms of wind power systems can result from errors in voltage balance or converters, uncertainties in regard to prediction models, cyberattacks, minimal inertia in electric system, cyber vulnerabilities in smart grids, and, for example supply chain issues in critical materials. Three solution models were identified: cyber resilience, high quality electric system management, and organizational capabilities. According to the scenario analysis, serious disturbances may occur due to, for example, cyber activities, errors in electricity systems or due to so-called spallated dangers. Based on the results, especially by improving organizational readiness and capabilities, one can increase preparedness to all kinds of errors and mitigate effects of all three scenarios.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2024-09-25T06:10:02Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2024-09-25T06:10:02Z (GMT).
