Abstract

This paper presents a particle swarm optimization PSO to solve hard combinatorial constrained optimization problems such as nonconvex and discontinuous economic dispatch ED problem of large thermal power plants. Several measures have been suggested in the control equation of the classical PSO by modifying its operators for better exploration and exploitation. The inertia operator of the PSO is modulated by introducing a new truncated sinusoidal function. The cognitive and social behaviors are dynamically controlled by suggesting new exponential constriction functions. The overall methodology effectively regulates the velocity of particles during their flight and results in substantial improvement in the classical PSO. The effectiveness of the proposed method has been tested for economic load dispatch of three standard test systems considering various operational constraints like valve-point loading effect, prohibited operating zones POZs, network power loss, and so forth. The application results show that the proposed PSO method is very promising.
