Welcome to the After Project Website !
project addresses the challenges posed by the need for vulnerability
evaluation and contingency
planning of the energy grids and energy plants considering also the relevant ICT systems used in protection and control.
Project emphasis is on cascading
events that can cause catastrophic outages of the electric power systems.
The main addressed problems are related to high impact wide spread multiple contingencies, the most significant wide area criticality. This kind of contingencies and the following cascading effects can be caused by either natural threats (e.g. lightnings, storm, fires, floods) or human related threats
(e.g. deliberate acts of terrorism, sabotage, human errors) or even a combination of both.
In particular, two major objectives are addressed.
The first is to develop a methodology and tool for
the integrated, global
vulnerability analysis and risk assessment
of the interconnected Power Systems considering interdependencies
(Information Communication Technology) systems. The adoption of risk concepts leads to a more in-depth, quantitative evaluation of the security
of the electrical power system. Moreover, linking threats to system contingencies permits to dynamically change the set of (single and multiple) contingencies
under investigation according to current environmental conditions. This allows to fully exploit large set of data (big data
) coming from on-line monitoring systems available at TSOs’ control centers. A fundamental outcome of the tool consists in risk-based ranking list of contingencies, which can help operators decide where to deploy possible control
The second objective is to develop algorithms and tools supporting contingency planning in a two-fold approach:
- preventing or limiting system disruption, by means of physical security techniques and defence plans;
- re-establishing the system after a major disruption, by means of restoration plans.
A language to model defence plans functionalities and ICT architecture is developed. New defence plan concepts are also introduced to cope with emergency situations.
