    1. Dynamic Performance of Distribution Systems with Distributed Generation Zhenyu Fan IEEE Student Member Adly A, Girgis IEEE Fellow Clemson University Electric Power Research Association

    2. OUTLINE • Introduction • Objectives • Modeling and System description • Simulation and Results • Conclusions Clemson University Electric Power Research Association

    3. Introduction • Fault Analysis: a symmetrical component-based approach • Induction Machine: widely used in the system • DG (Photovoltaics) Modeling: power electronics related Clemson University Electric Power Research Association

    4. Goals • Fault analysis in distribution system with IM and DG(PV) • The effects of DG(PV) in the faulted system • The correct operation of DG and loads under the fault condition Clemson University Electric Power Research Association

    5. Example system: Subsystem 2 5 6 7 4 1 2 Subsystem 1 3 Clemson University Electric Power Research Association

    6. System Description by PSCAD Clemson University Electric Power Research Association

    7. System Description by SIMULINK Clemson University Electric Power Research Association

    8. Fault Analysis 1. Normal distribution system Steady State Single phase A-ground fault (0.1-0.15 sec) Clemson University Electric Power Research Association

    9. Fault Analysis 2. With Induction Motor Single phase A-ground fault (0.1-0.15 sec) Disconnect IM after 0.45 secs Disconnect IM after 0.15 secs Clemson University Electric Power Research Association

    10. Fault Analysis 3. With Photovoltaics Single phase A-ground fault ( at 1.8 sec, PV disconnected from system at 1.9 sec) Clemson University Electric Power Research Association

    11. Fault Analysis 4. With IM + PV (case 1) Single phase A-ground fault ( at 1.7 sec, 1.73s(2 cycles) open breaker of Motor, 1.8s disconnect PV, 1.9s fault cleared ) Clemson University Electric Power Research Association

    12. Fault Analysis 4. With IM + PV (case 2) Single phase A-ground fault ( at 1.7 sec, 1.73s open breaker of PV, 1.8s disconnect Motor, 1.9s fault cleared ) Clemson University Electric Power Research Association

    13. Comparison of Matlab/Simulink and PSCAD Clemson University Electric Power Research Association

    14. Conclusions • The waveform of the fault current and voltage become worse because of the induction machine. • PV generated the harmonics into system, so some filters are needed. • During the fault, DG should be tripped before the fault is cleared. • The accurate operation and smart control of DG and loads can damp the oscillation and make the system stable.
