The concept of short-circuit power and the assessment of the flicker emission level

Abstract

Field experiences have demonstrated that existing flicker emission assessment approaches do not always lead to good results. The existing approaches (the simplified approach and voltage drop approach) suppose that active power variations and resistive component of power system impedance can be neglected. The present paper demonstrates that this hypothesis may lead in some cases to important errors and proposes a new assessment method the load current approach, which takes network resistance and active power fluctuations into account, to overcome this problem.
