OPTIMIZING THE PLACEMENT OF FACTS DEVICES USING EVOLUTIONARY ALGORITHM CS 448 Project By Radha Kalyani Professor Dr. Daniel R Tauritz
OUTLINE • Motivation • Problem Statement • EASQP Motivation • Specifications of EA • Experimental Setup • Experimental Results • Conclusion & Future Work
Motivation • Blackout in Power System – • Cascading Failure • Terrorist Attack • What can we do? • Install a fast reacting device to control the power flow • UPFC - Third generation FACTS device - Versatile - Controls various parameters of Transmission Line ( Real and Reactive Power ) • How can we use FACTS effectively? • Placement + Settings - Maximize System Performance - Economic use of device - Better coordination of devices
Problem Statement • EA Placement + SQP Settings (EASQP) EA Placement Black Box SQP Black Box Max Flow Algorithm • Max – Flow Control settings + Heuristic Placement (MFH) • Vs • EA Placement + SQP Settings
EA Motivation • Brute Force • 1 to 2 • 3 • 4 or More Fair • Evolutionary Algorithm • Power Flow Equations • Non smooth surfaces • Discontinuous functions • Non differentiable equations • Simple to Implement • Robust
Sequential Quadratic Programming Optimization
Specifications of EA • Fitness Function for the Settings (SQP) Maximize PI = - [SlineL/ Smax]2 SCLs lineL • Proposed Specifications of EA
Line 20 Line 28 Line 28 Line 22 Line 22 Line 20 FACTS Line 23 Line 23 Line 24 Line 24 Line 21 Line 21 FACTS Customized Specifications of EA • Initialization - Random Initialization ( Popsize – 1) + Best Solution of MFS • Mutation - Move FACTS device from the present line to its neighboring lines
Experimental Setup IEEE 118 BUS DATA 118 buses, 186 lines, 20 generators
Experimental Results • Number of FACTS devices Installed – • 2 FACTS • Parameter Sets
Experimental Results • For 2 FACTS devices Final Best Parameter Set - Parameter Set 3 Placement – ( 69, 158 )
EASQP Placement IEEE 118 BUS DATA
MFH Placement IEEE 118 BUS DATA
Conclusion & Future Work • EASQP performed better than MFH • Time performance of EASQP has to be improved • Increase FACTS devices • Compare Brute Force with SQP Vs EASQP
