Two Stage Approach for Economic Dispatch in Using Quasi-Oppositional Based Particle Swarm Optimization

This paper presents a practical approach to implement the economic power dispatch of the power system. The proposed economic dispatch method consists of two stages. The first stage involves the economic power dispatch with considering network loss using quasi-oppositional Based particle swarm optimization technique. The second stage involves economic dispatch considering network loss and security constraints, where two objectives are proposed for the second stage. One is loss minimization, and another is the minimum movement of generator output from the initial generation plan. For showing the effectiveness of the proposed two stage economic dispatch approach, the six unit system is used for testing. The test results show the two stage dispatch method can not only reduce the system losses and system fuel consumption. Citation: Dr.K.Gnanambal, K.L.N College of Engineering ; A.
