A New Smart Grid Control and Operation Concept - Autonomic Power System

摘要

As the distributed energy resource (DER) penetrance increasing, future power system will be more large-scale with much complexity and uncertainty. Taking an active approach, active distribution network (ADN) can deal with future complex and uncertain challenges to some extent. However, too much re-lying on information exchange of each layer, ADN will lack global adaptability and stability. To make up for the deficiency, this paper proposes a new smart grid control and operation concept, namely autonomic power system (APS). Based on goal-directed mechanism, APS obtains global self-adaptive management. Meanwhile, under the concept of distributed coordination and autonomic control, autonomic units (AUs) in APS coordinate each other and make their own autonomic operation. APS takes not only an optimally and co-ordinately active control of power system, but also brings more intelligence with characteristics of self-configuration, self-optimization, self-protection and self-healing, i.e. self-management and overall self-adaption. Thus, APS completes real-time dynamic goals and makes the operation of future power system more intelligent, effective, safe and reliable.
