Small signal stability analysis is an effective tool for analyzing system stability and performance. Disturbances of small magnitudes are very common and low frequency oscillation is a major problem in large scale interconnected systems. Power System Stabilizers are used to generate auxiliary control signals to the generator excitation input and have a great impact in damping out low-frequency oscillations...
In this paper, a novel meta-heuristic technique named Symbiotic Organisms Search has been applied to solve different economic dispatch problems while satisfying various inequality and equality constraints. The proposed technique describes the interactive behaviour of various organisms in nature. Symbiotic relationship means two organisms rely upon one another for survival. To validate the performance...
This paper presents a Differential Search (DS) algorithm to solve the complex economic load dispatch (ELD) problems. DS algorithm utilizes the Brownian-like random-walk movement used by an organism to migrate. Prime focus of ELD is minimization of fuel costs of thermal generators, involving different constraints such as power balance, ramp rate limits and prohibited operating zone etc. The performance...
