Abstract :
As power electronic devices are widely used in recent years, the dynamic behaviors of power systems become much more complicated, which are composed of electromechanical transient and electromagnetic transient. Therefore, a hybrid simulation tool for multi-timescale power systems is highly demanded. In this paper, a new hybrid simulation algorithm is proposed based on the energy balance of boundary buses. The energy balance is formulated as a boundary equation expressed in implicit function and solved in an iterative manner. A modified IEEE 9-bus system is used for case studies and test results are compared to PSCAD, which validates its accuracy.
