Power Stabilizer Performance Based On Fuzzy Controller Compared To PID Controller

Electro-mechanical oscillations are produced in the machines of an interconnected power network, followed by a disturbance or due to high power transfer through weak tie lines. These  oscillations  should  be  damped  as  quickly  as  possible  to  ensure the reliable and stable operation of the network. To damp these  oscillations  different  controllers,  based  on  local  or  wide  area  signals,  have  been  the  subject  of  many  papers.  This  paper  presents  the  analysis  of  the  PID  of  Conventional  Power  System  Stabilizer  (PSS)  and  Fuzzy  Logic  Controller.
