Abstract

Load representation has a significant impact on power system analysis and control results. In this paper, the interaction between static load, motor load and wind farm connected to a distribution network is described in the context of bifurcation analysis. The wind farm is represented considers both constant speed and variable speed inductions generators. Motor loads are assessed with respect to their mechanical loads. The network is represented by three models: a differential equations model (ODE), a differential-algebraic equations model (DAE) with a voltage dependent static load, and a DAE model with a fully dynamic load. A differential algebraic representation is developed; and the study is based on the determination of bifurcation points. The bifurcation analysis has indicated the occurrence of saddle-node and Hopf bifurcations. The bifurcation points indicated the load-generator dynamic interaction and the network permissible wind power penetration. Bifurcation analysis has shown the effect of the dynamic load on the dynamic stability of the network.
