Abstract

The monitoring and control of future power system are expected to be characterized by the distribution of functions and by the dependence on communications. Distributed monitoring and control appear because of the intrinsic features of new resources (generation and storage), because of the participation of loads in the energy management, and because of the need for fast, local reactivity for dynamic control and protection. Given the finer granularity of the controllable energy entities, and given the natural variability of some renewable sources, the sensitivity to individual load variation is greater than in traditional systems. Interactions between continuous dynamics and discrete events – that are an intrinsic part of power system behavior – are becoming more relevant due to the increasing number of power electronics converter and the use of networked control schemes. Furthermore, the future energy grid is expected to incorporate electrical, gas and heat networks, to achieve maximum usage of the available energy in every form, and storage capacity particularly in thermal form. In this context the design of each part (subsystem, component, algorithm, logic) is a challenge due to the interactions, and due to the dimensions of the problem. The presentation will focus on a review of current status and expected evolution of terrestrial power systems and on the system level challenges associated with that.
