A Hybrid Simulation Tool for Distributed Generation Integration Studies

• This work presents a hybrid simulation tool thatcombines fast analysis of quasi-static time series or transient stability programs and electromagnetic transients ones to evaluatethe dynamic behaviour of electric power systems with distributedgeneration sources. The interaction between the two programs isperformed by means of controllable current and voltage sources,which are used to interface external and detailed systems. Thedouble second order generalized integrator (DSOGI) is used toextract the positive-sequence phasor from the detailed systemto the external one. A local network server controls the datacommunication between the two simulation environments bymeans of the TCP/IP protocol. In the present paper, the proposedtool is used to simulate the integration of a wind power plant,based on a doubly-fed induction generator (DFIG), into a 29-bus electrical network. Results and computational timings arethen compared with the ones obtained with an electromagnetictransients program, which demonstrate the accuracy and speedof the proposed strategy.
