Assembling of Decision Support System – Software Implementation

Start date or Starting Event: 14



This WP assemblies a prototype DSS, which is then refined after a series of trial applications (see WP 6 and WP 7). It receives as an input the system specification of WP 4.

The assembly operation is carried out and supervised by the software coordinator.

Output of WP5 that is used as input for WP6 and WP7:

  • Software implementation of DSS


Description of work

  • Task 5.1 – Prototype Software Implementation of DSS (Leading Partner: INDRA)
    The System Specification developed in WP 4 is implemented to an all inclusive prototype software tool.
    All the prototype software implementing activity is supervised and coordinated by the software coordinator.

  • Task 5.2 – Refinement of Software Implementation of DSS (Leading Partner: INDRA)
    The knowledge obtained from the trial applications is transferred to the DSS in this step.



This Work packages gives the Central Deliverable of this project:

  • Del 5 – Applicable Decision Support System software
    A prototype software Decision Support System is given, that allows the user to identify the most effective measures in order to secure a regional power infrastructure integrated in the European power grid against cascading effects through accidents or deliberate acts of terrorism.

    This Decision Support System enables the user:
    • to identify the vulnerabilities of the analyzed grid and production plants and to detect their origins,
    • to estimate the damage / impact of real or simulated network failures precisely,
    • to identify the possible measures for prevention of outages and acceleration of automatic restoration and
    • to rank these measures according to their effectiveness and their cost-benefit ratios,
    • to carry out contingency analyses of the transmission and distribution network and the generation facilities.

The DSS uses as input the configuration of the analysed grid. Furthermore the user defines scenario incidents of interest (attack on number of lines, attack on ICT, power plant break down, weather phenomenon…). This scenario definition also includes the level of capacity utilization of interest, or if some parts of the network is under maintenance. On the basis of this data input, the vulnerabilities of the network are identified and the probability that the scenario incidents lead to a large-scale interruption are quantified.
The DSS does then simulate the effects of the scenario incidents and gives full information on the impacts. The impact will be given for the infrastructure (cascading paths, effected regions, expected duration for restoration of network functionality, …) and for the economic / public effects (damage for businesses and households).
The DSS does also suggest effective measures to reduce or prevent the effects of the scenario incidents. The implementation of these measures is then simulated and the impact of the scenario incidents is re-calculated. Thereby, the effectiveness of the suggested measures is revealed.
The difference of the impact of the simulated incidents is then compared for the status-quo grid and for the protected grid (as suggested by the DSS). Thereof the benefit (i.e. the mitigated monetized damage and the number of affected individuals) of the countermeasures can be compared with the estimated costs of their implementation. Thereby a decision whether to implement the measure or not is rationalised.
