Incorporation of SVCs into energy function methods

Abstract

The incorporation of static VAr compensators (SVCs) into energy function methods is described. The consequences of SVCs encountering limits are of particular interest. At a limit point, the network description undergoes a change. System behavior is not smooth. This lack of smoothness is investigated. A valid energy function, which includes the effects of SVCs and their limits, is established. Stability assessment results, obtained for a real power system, demonstrate the effects of SVC limits. It is shown that the theory developed for handling limits can be applied to models of other power system components.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
