Working on my PhD, title: "Policy-Based Communication for the Control of Power Systems". The basic idea is to use higher-level data formats in control communication, and to especially investigate the idea of policy-based communication that splits control communication into two distinct parts: agreeing on a behaviour to execute, and then executing this behaviour by responding to trigger signals.I also contributed significantly to the development of the software that controls the… Show more Working on my PhD, title: "Policy-Based Communication for the Control of Power Systems".
