An Integrated Assessment of Super & Smart Grids

Solutions for Smart and Super Grids with HVDC and FACTS

Deregulation and privatization are posing new challenges to high-voltage transmission systems. High-voltage power electronics, such as HVDC (High Voltage Direct Current) and FACTS (Flexible AC Transmission Systems), provide the necessary features to avoid technical problems in heavily loaded power systems; they increase the transmission capacity and system stability very efficiently and assist ...

Cybersecurity Risk Assessment in Smart Grids

Smart grids will make extensive use of information and communication technology (ICT) to enable the integration of renewable energy sources. Consequently, future power grids come with a much larger cyber-attack surface, which makes cybersecurity risk assessment a major concern. Due to their cyber-physical nature, risk assessment in smart grids is a challenging task. Moreover, the complex mix of...

Smart Grids

Smart - Grids

We build a system dynamics model to evaluate the potential dynamics of consumer adoption of “Smart Energy Behaviour”. Within this term we include different levels of: i) shift in electricity consumption towards less costly-less polluting and congestioning hours; ii) the reduction of mainly wasteful electricity consumption, that maintains similar levels of comfort; iii) the enrolment in demand r...

Cyber Risk Assessment of Transmission Lines in Smart Grids

The increasing use of information technologies in power systems has increased the risk of power systems to cyber-attacks. In this paper, we assess the risk of transmission lines being overloaded due to cyber-based false data injection attacks. The cyber risk assessment is formulated as bilevel optimization problems that determine the maximum line flows under false data injection attacks. We pro...
