Query: Extending the Dissipating Energy Flow Method to Flexible AC Transmission
  Systems   In recent years, the dissipating energy flow (DEF) method has emerged as a
promising tool for online localization of oscillation sources. In literature,
the mathematical foundations of this method are well-studied for networks with
synchronous generators. In this paper, we extend the analysis to flexible AC
transmission systems (FACTS). To that end, we derive the DEF-expressions for a
thyristor controlled series capacitor (TCSC) and a static synchronous
compensator (STATCOM) operating with conventional control strategies. Analyzing
their respective DEFs, we obtain the conditions for which these FACTS devices
could behave as the sources of oscillation energy. Our findings are structured
into propositions and are supported through numerical case studies on IEEE test
systems.
