Intelligent Energy Systems: Introducing Power-ICT Interdependency in Modeling and Control Design

This paper introduces a novel control scheme for mitigating the cascading effects of a failure in the power transmission grid. Modern power systems include controller entities, which exchange information (measurement/control signals) with the grid through ICT (Information Communication Technology). Nevertheless, networking problems can generate observability/reachability issues that prevent the controller from correctly estimating the grid's state and timely applying the necessary actions. Thus, we present a control approach that explicitly takes into account the potential degradation of the ICT performance during power failure events. To this end, the power induced ICT deficiencies are modelled as additive communication latency, so as to quantify their impact on the controller’s effectiveness. Moreover, in order to overcome excessive/varying delays, a Model Predictive Control (MPC) architecture is proposed, which produces directives for both the safeguard cut of power lines and the load/generation regulation, in a manner that minimises the impact of the initial power failure on the overall grid.
