STRUCTURE OF AN ELECTRICITY NETWORK

ELECTRICITY NETWORK ASSUMPTIONS▪ Various cable types may have different

repair times for each damage.▪ If the number of damaged cables

exceeds a predefined value, then they would be replaced with emergency overhead lines.

▪ Priority would be given to the sensitive sites like hospitals, fire brigade offices, police stations and other emergency management centres.

7

REPAIR ASSUMPTIONS

ROAD NETWORK ASSUMPTIONS▪ Whole region is divided into different

roadzones▪ A matrix is developed that shows

probable number of days needed to have road access between different zones

▪ Road access time is helpful during the calculation of various damaged components of electricity network

REPAIR ASSUMPTIONS

Step 1 - Understanding the characteristics of infrastructure network Step 2 - Composition of fundamental models for componentsStep 3 - Dependency Identification Step 4 - Identification of common featuresStep 5 - Computation of Recovery timeStep 6 – Development of Outage Maps

ONGOING AND FUTURE WORK

DEVELOPMENT OF A DECISION SUPPORT SYSTEM AROUND THE SIMULATION FRAMEWORK

DSS BASED ON DESIGN SCIENCE

understanding of the real world

where DSS will be applied

Knowledge of basic components, processes

and tasks carried out by the users

Identify various classes of users that are

expected to work with the DSS

Analyse specific functions that the DSS is expected

to provide.

Design Cycle

Development and Evaluation Cycle

▪ Can model electricity and road networks of any region (water network model in progress).

▪ Customizable repair strategies.▪ Customizable network paths with option to add and

delete any link between sources and destinations▪ Batch processing of multiple damage models.

Corresponding outage maps will be generated for each damage model.

▪ A comparison of different outage maps could be helpful to select the best recovery strategy.
