1 213 PDCI Probing Test Analysis JSIS Meeting Salt Lake City, UT June 11-13, 213 Dan Trudnowski

2 Testing Benefits Monitor Oscillatory Dynamics Base-line system modal properties Freq, Damping, Shape Model validation with respect to oscillations Data base for modal analysis software and research Wide-Area Oscillation Damping Control Evaluate the potential impact of modulation control on system dynamics Provide key base-lining transfer functions under varying operating conditions Provide comparative information to model-based studies Evaluate control-system robustness, scaling, and gain properties 2

3 Major WECC Modes Mode Shape Interaction Path(s) Controllability Grade Comments NS A.25 Alberta vs System. BC and PNW swing with Alberta Alberta Interconnect. COI. Cust. Alberta B An Alberta trip causes NSA and NSB to combine into one NS mode with reduced damping. Need to understand damping better. NS B.38 Alberta vs (BC + N. US) vs (S. US). Alberta Interconnect. COI. Cust. Boundary. Wide-spread. PDCI B This is the most wide spread mode in the system. Need to understand damping better. EW A.5 (SW US) vs (Mid W. - CO) Unkown Unkown D Need PMUs in west part of loop. MT.55 to.8,.8 typical MT vs system. Garrison. Colstrip C Sometimes MT swings against BC. BC.6 BC (Kemano) vs system. Ripples to S. Cal. Cust.? Kemano? C Strong interactions with PDCI and PNW. EW B.7 Unknown Unkown Unkown F NOTE: "Grade" is a measure of how well we currently understand this mode. 3

6 Modal Conclusions (as of 212) (1/3) NS Mode A (.25 Hz) Damping nearly always 1% or higher. Shape depends on Alberta connection impedance. By far the largest observability point is Alberta. Rarely controllable from PDCI with Alberta connected. Less excitable throughout the interconnect. By far the largest controllability point is Alberta (model study). Controllability/Observability depends on Alberta interconnection impedance? (Undrill). NS Mode B (.36 Hz) Damping typically less than NS Mode A (5% to 12%). Shape is very consistent. Wide spread observability. Very controllable from PDCI. Very excitable throughout the interconnect. Very wide-spread controllability (model study). Alberta participation is moving north of Langdon. This is the one that would likely go unstable with Alberta connected? 6

7 Modal Conclusions (as of 212) (1/2) With Alberta disconnected NS Mode A disappears NS Mode B to.32 Hz and is more lightly damped. Shape does not change much. Very controllable from PDCI (mostly simulation). 7

8 PDCI Control Conclusions (as of 212) PDCI can provide damping to NS Mode B and NS Mode when Alberta disconnnects. Very Robust (Consistent) Candidate feedback signals: (North of DC line)-(south of DC line) freq. (North of DC line)-(malin) freq (North of DC line) freq. 8

9 Three Viable Feedback Signals 1. N. PDCI S. PDCI freq. No robustness issues in MiniWECC studies. No robustness issues in PDCI probing tests. No transient stability issues. Does not interact with Speed gov. High-freq. gain issues (need new sensor approach or loop filtering). 2. N. PDCI Malin Non-minimum phase zero in MiniWECC new 1 Hz. No robustness issues in PDCI probing tests. No transient stability issues. Does not interact with Speed gov. High-freq. gain issues. Worse than N.PDCI-S.PDCI (need new sensor approach or loop filtering). 9

10 Three Viable Feedback Signals 3. N. PDCI freq. Requires washout filtering. Minor non-minimum phase zero in miniwecc studies. No robustness issues in PDCI probing tests. Destabilizes transient stability for a gen. trip in the south. Interacts with speed gov. High-freq. gain issues (need new sensor approach). 1

16 213 Testing Goals Start understanding EW Mode A. PMUs on the west side critical. Continue base-lining NS A, NS B, BC, and MT. Need Kemano PMU. Develop base-line Oscillation Detection RMS Energies for All major power plants (MW, kv) All major interties (MW, kv) All major load centers (kv) Tune Mode Meter applications. Test data for constructing PDCI damping control Feedback signal. Develop a set of linear parametric models (SysID). 16
