2 Revisit hybrid simulation Theory & method First proposed for AC/DC system simulation [1] Frequency dependent network equivalent (FDNE) was introduced [2] Parallel interaction protocol [4] Real time -TS hybrid simulation [5] [6] Improved network equivalent [8]; interaction protocol [8] [9]; iteration [9] Develop ment Proof of concept DC & in-house TSP based [3] E-TRAN, the first commercial tool [7] ADPSS platform at CEPRI[5] SMRT: RDTS based Real time hybrid simulation by CSG and TH [10] OpenHybridSim: open source tool for hybrid simulation [8] 2

3 Status quote of hybrid simulation Targeted for transmission systems Typically two subsystems: one for, one for TS Mainly applied to HV AC/DC power systems Credit: The original figure was created by Prof. Xiaoming Yuan, HUST, China. Modified for this presentation Positive- or threesequence based TS : Electromagnetic transient TS: Transient stability 3

4 The power electronification trend in power industry Proliferation of renewable and distributed energy resources (DERs) PV, wind, storage, EV Connected to the edge of power grids through power electronic (PE) converters Power electronification Generations, transmissions and loads are increasingly moved behind the power electronic converters Hybrid simulation as-is is not designed for such power systems 4

8 Key features of the proposed approach A direct response to the simulation demands of the power electronification trend Flexible for different simulation scenarios Transmission system + power electronics (conventional hybrid simulation) Distribution system + power electronics Transmission + distribution + power electronics Suitable for both distributed and multi-core parallel computing 8

9 Open Implementation Open implementation approach Change from independent research to collaborative solution No funding sought at this starting stage Requirements and inputs from the power engineering community Open source the implementation (hosted at GitHub The following parties have shown their interests InterPSS development team ( Prof. Vijay Vittal s research group at Arizona State University Prof. Chen Shen / Yin Chen s research group at Tsinghua University The open approach has been successful in so many areas, we want to try it in the power system simulation software development. 9

10 Conclusions After 30+ years R&D, the -TS hybrid simulation has been commercialized and successfully applied for largescale applications The power electronification trend calls for extending the modeling and simulation domain boundaries of existing hybrid simulation approach A generalized piecewise algorithm based co-simulation approach is proposed An open implementation approach is proposed for the development More parties are welcome! 10
