Motivated by projects in Sweden on voltage stability analysis and associated load modelling, a simple dynamic load model is proposed which captures the usual nonlinear steady-state behaviour plus load recovery and overshoot. The parameters of the model can be related to physical devices depending on the time zone following a disturbance. Some simple, but seemingly important dynamic voltage stability analysis is developed based on the model.
