Abstract
A vital requirement of the power system is always to maintain a balance between the generation and the demand. To meet the increasing demand and simultaneously decrease the carbon footprint of the power grid, fossil fuel-based energy sources are being phased out and distributed renewable energy sources are being integrated into the power grid. These renewable energy sources increase the unpredictability of power generation, as they are dependent on factors such as the sun and the wind. This unpredictability can threaten the system's resilience in extreme cases where the generation and demand deviate excessively. A solution to tackling this unpredictability is using Information and Communication Technology (ICT) systems, in both a proactive and reactive sense, for power grid services. Proactively, forecasts of generation and demand can be used to schedule system operations to maintain the balance between generation and demand, thus making the system plannable. Reactively, in case of deviations from the planned schedule, certain generation flexibilities can be activated to ensure the generation meets the demand. However, imprecise generation prediction could lead to insufficient flexibility to restore a balance between generation and demand, leading to cascading impacts on the power system. This reliance of the power system on the ICT system introduces a mutual dependency, where the power system relies on ICT for monitoring, control and decision making and ICT relies on the power system for power supply. Consequently, issues such as incorrect and unavailable data and increased communication latency can lead to erroneous decisions being taken in the power system. These issues impact the resilience of the system since the erroneous decision taken may not remedy the existing challenge and, in fact, may exacerbate its impact. Protection systems are also affected by issues arising from ICT systems, where extended communication latency can lead to delays in isolating faults in a power system. Furthermore, incorrect data could lead to undetected power system faults, threatening power system stability. In extreme cases, such as in power system blackouts, an ICT system is essential to restoring the power system. Nevertheless, the power and the ICT system should be restored while maintaining a sufficient service level. In this case, imprecise data and predictions could lead to sub-optimal restoration of the power system, leading to economic penalties for the grid operator.

||
| Complex Systems and Computer Networks: Opportunities and Challenges Marcello Trovati (Edge Hill University, UK) |
||
Abstract
Complex systems are defined by their connected nature, their nonlinear dynamics, and emergent properties. These systems, often described as networks, consist of multiple nodes and large number of evolving connections.
As a consequence, there is a close relationship between complex systems theory and computer networks. In this talk, the common properties between these two research areas will be discussed, aiming to provide an overview of the underlying principles, as well as the related challenges and opportunities with a focus on the intersection of complex systems and computer networks, and potential future research directions Furthermore, the talk will also discuss how complex systems theory can be applied to analyse and investigate computer networks, including network resilience, traffic management, and overall security.
