Passivity Guaranteed Frequency Selective Time Domain Simulation of Very Large Linear Electric Power Systems

In this research, a new approach to efficiently simulate large RLC represent power systems will be introduced and implemented in RTDS. The new approach utilize principle component analysis to search the subspace of state space vectors corresponding to a customer designed frequency band excitations and using projection method to form the reduced order system. Unlike other frequency dependent network equivalent methods, the proposed method reserves all internal information of original system and also inherently guarantees the passivity of the equivalent network. The results of this study will provide a new module in RTDS. It can be used for efficiently modeling large RLC represented network. So, ultimately will enhance this part of the RTDS simulator.
