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

Field experiences have demonstrated that the existing flicker emission assessment approaches do not always lead to good results. The existing approaches (“the simplified approach” and the “voltage drop approach”) suppose that the active power variations and the resistive component of the 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 the network resistance and the active power fluctuations into account, to overcome this problem
