Abstract?This paper presents a particle swarm optimization (PSO) algorithm for solving economic load dispatch problem in thermal power plants. An additional inequality constraint, called real time efficiency of different generating units has been considered in order to calculate the economical generation shared by all the generating units. The effectiveness of the algorithm is validated by carrying out extensive test on a power system involving 6 and 8 thermal generating units. The results obtained are compared with the same system without taking efficiency in to consideration. The result shows that by taking efficiency as an additional operating constraint, a considerable reduction in total fuel cost is achieved. PSO approach is used as it is easy to implement and there are few parameters to adjust with high computational efficiency and high accuracy.
