Abstract :
This paper explores the interaction between dynamic loads and power systems. Based on a generic model of dynamic loads, the frequency response of such loads is discussed. Also, the frequency response of the system is investigated. It is shown that the dynamics of the load provide a feedback path which can influence the damping of the modal oscillations of the system. This influence is very dependent on load parameters as well as the system configuration. Under some circumstances damping can be improved, but under other conditions dynamic load may cause a decrease in damping
