Title: Safety and Security of Infrastructures.

Abstract: In the talk, I will discuss two subjects of crucial importance for critical infrastructures: safety and security.  Solutions provided by several ‘smart’ ideas: smart grids, smart cities, smart production, depend on exchange of data. Frequently, broadcasts of raw data is used, which is not secure at all. In the wrong hands data can reveal sensitive information and may also be supplanted with the intention of interrupting operation of the system. I will present an idea how to circumvent these problems by developing privacy-preserving estimation-, control- and fault detection- algorithms, which lean upon recent developments within secure computation. 

In the second part of the talk I will discuss safety. One of the questions, we wish to answer is about the probability of a fault or a malfunction in a system. I will sketch one particular technique which helps answering this question – the barrier certificate method. To create a barrier certificate, one re-formulates a safety enquiry into the language of optimization, here, semidefinite programming. Values of the barrier correspond to the safety level.

 

Title: Smart Laboratory for Water Infrastructures.

Abstract: This new laboratory will be able to reproduce water infrastructures such as district heating, water distribution and wastewater collection as well as their interconnection with the power grid. 

This modular laboratory will allow the users to configure different topologies and scenarios. Thus, it will make possible to test control strategies in a realistic environment before the real implementation. Therefore, the laboratory will facilitate the discovery and demonstration of solutions for common problems in the water cycle such as water leakages, transport delays in heat distribution or wastewater overflow.

Network elements like pipes, valves, pumps and tanks are scaled down to emulate the physical effects of any water network topology in a compact space, and the hardware architecture implemented will emulate the real data collection. This design process is validated first in a simulation environment that ensures that the laboratory modules maintain qualitative effects of a real water network.

This facility aims to be an open research environment for students and researchers and it will be ready by Q2 – 2019.
