Abstract

Current techniques for dynamic security assessment in power systems rely on direct methods. While they provide a useful screening tool, the operator needs fast simulation of the system dynamics on-line to select a wide range of operating options. In this paper we propose two approaches, one based on trajectory approximation and the other based on time scale separation in the system. Slow dynamics are separated from the fast dynamics to accelerate the simulation using the integral manifold approach. The final goal of the project is to make both techniques suitable for parallel processing. With the rapidly changing computer technology, it is not inconceivable that on-line dynamic simulation may become feasible just like on-line load flow.
