This paper is devoted to the development of a hybrid simulator which integrates the electromagnetic transients (EMT) simulator and transient stability (TS) simulator. It discusses how two very different simulators can be coordinated to work together and produce accurate solution. A new selection approach is presented to identify the interaction location for interfacing the EMT and TS simulators. Pseudo-transient caused by frequency mismatch during the interaction is discussed with remedy presented. Based on the interaction protocol proposed in the paper, case studies were performed on two test systems, 9-bus systems and 39-bus systems, to assess the performance of the integration on both EMT and TS aspects.
