Evolving Intelligent Distributed Power Grids
Presentation, Power Systems

| In the
last half-century, we have witnessed wholesale and essential changes in the
ways we structure and conceive of generation, transmission and distribution
systems. - Generation systems have evolved from high-inertia, schedulable, large rotating machines to low-inertia, power-electronics-based, small and distributed non schedulable renewable energy systems; - Transmission systems have evolved from traditional ACtransmission circuits and local protection systems to AC-DC transmission networks equipped with fast power electronics controllers (FACTS). Sophisticated wide-area protection and control schemes and communication systems are both used to maximize security, and power transfer capability to reduce rights-of-way; -Distribution systems can no longer be represented bysimple passive and dynamic load equivalents. Distributed energy generation and storage systems may now be integrated anywhere on the grid, including at customer sites. Each customer can potentially become a de-centralized ‘prosumer’ of sorts, with photovoltaics (PVs), batteries, and plug-in electrical This presentation will discuss the expected flexibility and capability of simulation tools and “digital twins” that will be required to cope with the increasing complexity of our shared modern and evolving intelligent distributed power grids. |
