Analysis & Visualization of Frequency in Power Systems Jessica - PowerPoint PPT Presentation

Analysis & Visualization of Frequency in Power Systems Jessica Wert Advisor: Dr. Héctor Pulgar-Painemal Mentor: Jonathan Devadason Final Presentation July 14, 2016 Knoxville, Tennessee

Application • Frequency stability • Frequency controls  Primary  Secondary  Tertiary • Inertial behavior 2

Application 3

Application • Fast-acting Energy Storage Systems (FESS)  Flywheels • Significance of center of inertia (COI) 4

36 Bus Test System – Description • Initially steady state conditions • Change to initial conditions applied • Results modeled 5

36 Bus Test System: Steady State 6

36 Bus Test System: delx0 = [0.02; 0.02; 0; 0; 0; 0; 0; 0;] 7

36 Bus Test System: delx0 = [0.03; 0; 0; 0; 0; 0; 0; 0.01;] 8

36 Bus Test System: delx0 = [0; 0.03; 0; 0; 0; 0; 0; 0.01;] 9

36 Bus Test System: delx0 = [0.02; 0; 0.02; 0; 0; 0; 0.02; 0;] 10

36 Bus Test System: delx0 = [0; 0; 0.02; 0.02; 0; 0; 0; 0.02;] 11

Conclusions • Impact of applied changes • Significance of COI • Necessity for FESS 5-12
