AbstractAlthough major space weather effects on power systems are infrequent, modern societies' dependence on electricity means that any power interruption will have widespread impact. There is also concern that damage to a significant number of transformers during a space weather storm could take many years to replace and restore the integrity of the power system. Thus there has been renewed effort to understand the space weather impact on power systems and to examine the feasibility of various mitigation strategies. This chapter provides a description of what happens during a space weather storm to cause power system problems. An examination is then made of the key parameters influencing each stage of the process. Finally it is shown how these factors combine to determine the risk of problems to power systems and influence the forecasting of space weather for the power industry.
Summary(Plain Language Summary, not published)
Space weather refers to the dynamic conditions on the Sun and in the space environment, in particular, in the near-Earth environment, that can affect critical infrastructure. NRCan operates the Canadian Space Weather Forecast Centre and conducts research into space weather effects on power systems, pipelines, radio communications and GNSS positioning to help Canadian industry understand and mitigate the effects of space weather. This chapter provides a description of what happens during a space weather storm to cause power system problems. An examination is then made of the key parameters influencing each stage of the process. Finally it is shown how these factors combine to determine the risk of problems to power systems and influence the forecasting of space weather for the power industry.
