Analysis
Lessons learnt from recent power emergencies and blackout incidents
Information from Cigr�
Large disturbances which interrupt supply to customers over wide areas occur every now and then despite best practices and efforts in planning and operating the power grid. Click here to read the full article
These disturbances are usually unpredictable, and they often result in interruptions to customers and damage to power system infrastructure followed by a lengthy restoration process, with serious social impact and loss in business productivity activities.
In recent years, Large Disturbance Workshops were held during the Cigr� Paris Sessions to share information on causes and impacts of large disturbances, and a transmission system operator's (TSO's) experience in managing the disturbances. Owing to the limited time allocated to each event, the information is often presented at a very high level.
To investigate the main causes of large disturbances in more depth and to develop lessons learnt in greater detail, a separate, focused exercise is needed to fully analyse these events with an objective to identify trends and develop possible remedies. Working Group (WG) C2.21 has completed a series of event analyses to pursue this objective.
This article presents the key findings of the working group, focusing on the main causes and possible remedies to prevent the occurrence or mitigate and minimise the impact of large disturbances, and an assessment of control centres' performance in managing these disturbances... (more)
