Design for Resilience in Infrastructure Distribution Networks

چکیده
The recognition that resilience is a critical aspect of infrastructure resilience has caused the national and homeland security communities to ask “How does one ensure infrastructure resilience?” Previous analysis methods have primarily focused on system recovery activities following the occurrence of a disruptive event. In this report, we expand on those methods by including pre-disruption investment options, in addition to post-event recovery activities, as means to infrastructure resilience. The report describes a stochastic optimization model for designing network infrastructure resilience to a variety of uncertain potential disruptions. The model seeks investment-recovery combinations that minimize the overall cost to a regional distribution network. A set of numerical experiments illustrates how changes to disruption scenarios probabilities affect the optimal resilient design investments.

Hybrid Key pre-distribution scheme for wireless sensor network based on combinatorial design
Key distribution is an important problem in wireless sensor networks where sensor nodesare randomly scattered in adversarial environments.Due to the random deployment of sensors, a list of keys must be pre-distributed to each sensor node before deployment. To establish a secure communication, two nodes must share common key from their key-rings. Otherwise, they can find a key- path in which ens...

Events with low probability and high impact, which annually cause high damages, seriously threaten the health of the distribution networks. Hence, more attention to the issue of enhancing network resilience and continuity of power supply, feels more than ever, all over the world. In modern distribution networks, because of the increasing presence of distributed generation resources, an alternat...
متن کاملPrioritizing Resilience Enhancement Measures for Electric Distribution Networks Against Hurricanes
In recent years, climate change and increasing occurrence rate of high-impact rare (HR) natural events such as hurricanes have made it difficult to supply uninterrupted power to end-user customers. The extensive geographic area of electric distribution networks, as the last ring of the energy supply chain in power systems, has increased the vulnerability of these networks against natural events...
متن کاملImproving the resilience of active distribution networks by optimal charging/discharging management of electric vehicles in parking lots
In the event of a severe incident with a high impact and low probability of occurrence, distribution networks may be separated from upstream networks and several feeders may be disconnected simultaneously within the distribution networks. In such circumstances, to maximize the resilience of the distribution networks and to prevent long-term global outages, they are reconfigured and islanded to ...
متن کاملA New Index for Quantitative Assessment of Distribution Network Resilience in the Presence of Distributed Generations
Resilience is defined as the system ability to keep an acceptable performance level against a sever disturbance and to return to a stable condition in a suitable time. Occurrence of inconvenient weather conditions and natural disasters, which are growing in number and severity during the last years, has always led to damages and wide outage throughout the distribution network. Therefore the ass...
