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

• verhead lines.

▪

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

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 components Step 3 - Dependency Identification Step 4 - Identification of common features Step 5 - Computation of Recovery time Step 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.
