UPFC Controller Design for 2 Area Power System Stability with Fuzzy & Genetic Algorithm

This project presents the genetic optimization of the parameters of a fuzzy PI controller for UPFC( Unified Power
flow controller) using an improved genetic algorithm to enhance the transient stability performance of power systems. The function based Takagi-Sugeno-Kang (TSK) fuzzy controller uses minimum number of rules(hvo rules) and generates the proportional action which by one-to-two inference mapping gives a variable gain PI controller. This single input function based scheme dispenses the gain dependency of the proportional or
integral gains and generates independent control actions.Computer simulation results on a 2-area 4-machine 12-bus power system with an UPFC installed between buses sand r confirm the efficacy of the new approach in damping the local-mode and inter-area mode of oscillations.

During running the UPFC Controller Design for 2 Area Power System Stability with Fuzzy & Genetic Algorithm,I'v found the following error
Failed to load library 'powerlib_models' referenced by 'upfcfuzzy4_by_indraneek_saki/G5/Voltage Measurement1/model'

Two area four machine power system kunder

Excellent work sir, could u send me the code for
multi-objective GA code for SMIB . thanking you

Hello Sir;
It is not working in my MATLAB.
@ lolo koko,,,####
Please guide me

lolo koko

great work...........
can you please provide a multi-objective GA code for SMIB system......for power oscillation damping.......

thanks a lot

Dear Sir
Do you have matlab file Two area four machine system installed with UPFC kundur model? pls upload the file sir

Sir, I simulate your model. Error occur in Fuzzy logic controller. How can I rectify sir?

Dear Sir
Do you have matlab file for Kundur(Two area four machine system installed with UPFC controller) and WSCC(three machine nine bus system installed with upfc). If you have the above system means can u please upload the file.

Dear khaled nusair

i am very glad to help u.already i was uploaded IEEE 30bus with STATCOM and SSSC.if u want IEEE 30 BUS with UPFC i will uploaded soon.
