Reactive Power Flow over System Boundaries in the Distribution Grid

Abstract

The focus of this paper is the reactive power balance. The question, to what extent the reactive power flows at the system boundaries can be influenced, will be covered. On the one hand at the interface between transmission and distribution system operators. On the other hand, at the system boundaries within the distribution network. The challenge of the reactive power balance in the distribution grid in Salzburg is in the low load periods. During these time periods, the reactive power generation of the (cable) capacitances is not compensated by the reactive power consumption of the line and transformer impedances.
