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.
