3. Harmony search algorithm for power system stabilizer tuning. Sayed Mojtaba Shirvani Boroujeni, Babak Keyvani Boroujeni, Hamideh Delafkar, Elahe Behzadipour and Reza Hemmati. Indian J.Sci.Technol. Vol.4, Issue 9, pp: 1025-1030.
Abstract The problem of tuning Power system stabilizers (PSSs) is commonly formulated as a nonlinear optimization problem with some constraints. In this paper a new optimization technique based on Harmony Search (HS) to solve the proposed optimization problem is presented. This is a very complex nonlinear programming problem. A constructive heuristic algorithm aimed at obtaining an excellent quality solution for this problem is presented. Results of the tests, carried out with a multi machine electric power system, show the capabilities of the method and also the viability of using the HS to solve the problem. Keywords: Multi Machine Power System, Power System Stabilizer, Low Frequency Oscillations, Harmony Search
