  2. levinbr@ee.bgu.ac.il Outline • Terms Definition • Theoretical Background • System Overview • Summary

  3. levinbr@ee.bgu.ac.il Control Definition Ability to force the system perform purpose it designed for, in spite of distortions. In practice this aid, unreachable, of course. So the demand is that system will perform it in average.

  4. levinbr@ee.bgu.ac.il Stability Definition BIBO Boundary In  Boundary Out It means that every boundary input will causes boundary output Pay attention!!! Boundary output doesn’t deny ripple

  5. levinbr@ee.bgu.ac.il Close Loop Control • The system is given and can’t be changed • Controller parameters can be changed in order to achieve wanted output

  6. levinbr@ee.bgu.ac.il FACTS FACTS is alternating current transmission systems incorporating power electronic-based and other static controllers to enhance controllability and increase power transfer capability FACTS=Flexible ACTransmission System

  7. levinbr@ee.bgu.ac.il Grid Code The Grid Code establishes the basic rules, requirements, procedures, and standards that govern the operation, maintenance, and development of the Transmission System

  8. levinbr@ee.bgu.ac.il Power • Power is defined as the rate of flow of energy past a given point • Active Power • Reactive Power • Complex Power S=P+jQ

  9. levinbr@ee.bgu.ac.il Active Power • Magnitude

  10. levinbr@ee.bgu.ac.il Reactive Power • Magnitude • Phase

  11. levinbr@ee.bgu.ac.il EDLC Ion An ion is an atom or molecule where the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge Cation Number of protons > number of electrons Anion Number of electrons > number of protons

  12. levinbr@ee.bgu.ac.il EDLC Electric Double-Layer Capacitor Discharging Charging

  13. levinbr@ee.bgu.ac.il EDLC ELDC Bank Equivalent Circuit

  14. levinbr@ee.bgu.ac.il EDLC ELDC Properties • Up to 1 million recharging cycles • Clean Power element • High rate charging/discharging • High efficiency • Non Polar element

  15. levinbr@ee.bgu.ac.il Space Vector

  16. levinbr@ee.bgu.ac.il Clarke Transform

  17. levinbr@ee.bgu.ac.il Park Transform

  18. levinbr@ee.bgu.ac.il Power Sensing

  19. levinbr@ee.bgu.ac.il STATCOM STATCOM=STATIC+COMPENSATOR VSC=Voltage Source Converter

  20. levinbr@ee.bgu.ac.il STATCOM/BESS STATCOM with Battery Energy Storage System Active Power Compensator BESS disadvantage • Based on chemical process • Low response speed • Short service life

  21. levinbr@ee.bgu.ac.il ECS ECS=Energy Capacitor System Energy capacitor system (ECS) composed of power electronic devices and electric double layer capacitor (EDLC)

  22. levinbr@ee.bgu.ac.il ECS ECS Block Scheme

  23. levinbr@ee.bgu.ac.il ECS ECS Proposed Topology

  24. levinbr@ee.bgu.ac.il Conventional Set • Crisp Set Crisp set is function that map a value, which might be a member of a set, to a number equal zero or one, indicating is it member or not 5 is member of {1,2,3,4} => 0(FALSE) 2 is member of {1,2,3,4} => 1(TRUE)

  25. levinbr@ee.bgu.ac.il Fuzzy Logic • Fuzzy Set Fuzzy set is function that map a value, which might be a member of a set, to a number between zero and one, indicating its actual degree of membership 5 is member of {1,2,3,4} => 0.9 (Almost the member) 2 is member of {1,2,3,4} => 1 (Member)

  26. levinbr@ee.bgu.ac.il Fuzzy Logic - Example • Is Saturday a weekend day? • 1 (yes, or true) • Is Tuesday a weekend day? • 0 (no, or false) • Is Friday a weekend day? • 0.8 (mostly yes, but not completely) • Is Sunday a weekend day? • 0.95 (Yes, but not quite as Saturday)

  27. levinbr@ee.bgu.ac.il Fuzzy vs. Conventional Logic

  28. levinbr@ee.bgu.ac.il Current Pump Control Block

  29. levinbr@ee.bgu.ac.il Simulated System

  30. levinbr@ee.bgu.ac.il Simulation Results
