A quantitative methodology to assess the process of service and infrastructure recovery in power systems

The paper proposes a quantitative methodology to simulate the process of restoring the electricity service and infrastructure with its uncertainties, highlighting the dependence of the main recovery characteristics (e.g. duration, energy not supplied) on different technical and environmental aspects (e.g. visibility, usability of roads, etc.).

Increasingly severe weather threats push system operators to apply a systematic approach to deal with emergencies. In this context, a good estimate of the time necessary to recover the electricity service and infrastructure plays an important role for restoration management. The paper proposes a quantitative methodology to simulate the process of restoring the electricity service and infrastructure with its uncertainties, highlighting the dependence of the main recovery characteristics (e.g. duration, energy not supplied) on different technical and environmental aspects (e.g. visibility, usability of roads, etc.). Simulations performed on a realistic HV (high voltage) network show that the results are consistent with operator experience and the approach can be used to improve the organization and management of the recovery process in the planning and emergency.
